Taking secrets to the grave is nothing new and eventually we will all most likely have a few secrets we take with us – perhaps to protect others or maybe to protect our own reputation or legacy. Some secrets, because of the historic consequences, or the attention given to them over the years, turn into a kind of mystery. This list consists of 10 such secrets that have been taken to the great beyond.
Erlandson started as an alfalfa farmer and started grafting and shaping tree trunks as a hobby. He would later over a period of decades train trees to grow into shapes of his own design. He experimented with birch, ash, elm and weeping willows, making loops, hearts, chairs, spiral staircases, zigzags, rings, birdcages, towers, picture frames and ladders. Erlandson found his trees to be a popular amusement and decided to create his “Tree Circus”. Erlandson would not tell anyone the secrets of his techniques and would carryout his graftings behind screens to protect against spies. Erlandson died in 1964 along with his amazing secret procedure used to propagate his trees.
Interesting Fact: In 1985, after the Tree Circus went out of business the trees were bought by millionaire Michael Bonfante and were transplanted in his amusement park Gilroy Gardens in Gilroy, California.
On Sept. 8, 1863 a fair-skinned stranger believed to be in his 20s was found by two fishermen at Sandy Cove in Digby County Canada. Both of the man’s legs had been freshly amputated and a jug of water and some bread had been placed nearby. The man was unable or unwilling to speak and is said to have uttered no more than two or three words after being found. One of the words was thought to have been Jerome and he was soon given that name. Jerome was filled with rage when certain words were spoken which led many to believe Jerome was carrying some kind of secret that he was not allowed to say. Jerome conducted himself with dignity and when offered money he would appear humiliated. There are many theories to who Jerome really was but no story has ever been proven. Jerome died April 19, 1912.
Interesting Fact: Jerome continues to be part of the collective psyche of the community where he was found. A residence for the handicapped has been named after him, songs have been written about him and he has also been depicted in paintings and a film.

During the fall of 1816 in Alexandria Virginia two people, a man and his wife walked into the Gadsby’s Tavern Hotel. The woman was ill and it was thought she was suffering from Typhoid fever. The woman’s condition continued to deteriorate despite being attended by one of Alexandria’s doctors. The husband then summoned the doctor and hotel staff and even the owner’s wife to the room to ask a very unusual request: He asked that everyone present swear an oath never to reveal their identities. All agreed and each took the secret to the grave. Several days after the oath was taken the Female Stranger died and to this day no one knows their identity. Before disappearing, her husband commissioned an extravagant headstone and buried her at St. Paul’s Cemetery in Alexandria Virginia.
Interesting Fact: The engraving on the headstone reads:
To the Memory of a
FEMALE STRANGER
whose mortal sufferings terminated
on the 14th day of October 1816
Aged 23 years and 8 months.
This stone is placed here by her disconsolate
Husband in whose arms she sighed out her
latest breath and who under God
did his utmost even to soothe the cold
dead ear of death.
How loved how valued once avails thee not
To whom related or by whom begot
A heap of dust alone remains of thee
Tis all thou art and all the proud shall be
To him gave all the Prophets witness that
through his name whosoever believeth in
him shall receive remission of sins.
Acts.10th Chap.43rd verse
The Leather Man was a wandering vagrant who traveled in an endless 365-mile circle between the Connecticut and Hudson rivers. He was Fluent in French but communicated mostly with grunts and gestures and dressed in crudely stitched leather from his hat to his shoes. He picked up cigar butts along his way and gratefully accepted offerings of fresh tobacco or cigars that townsfolk would give him as he walked silently through their villages. When asked of his background he would abruptly end the conversation. He was so reliable in his rounds that people would have extra food ready for him at a certain time every 34 days. It is unknown how he earned money, although one store kept a record of his order: “one loaf of bread, a can of sardines, one-pound of fancy crackers, a pie, two quarts of coffee, one gill of brandy and a bottle of beer.” After a blizzard in March 1889 the Leather Man’s body was found in his Saw Mill Woods cave in Sing Sing, NY. He died from cancer of the mouth most likely due to tobacco use. His bag was found next to him and contained leather working equipment such as scissors, awls, wedges, a small axe and a small prayer book which was in French.
Interesting Fact: The Leatherman’s tombstone reads, “Final resting place of Jules Bourglay of Lyons, France, “The Leather Man”. However the story published in the newspaper that claimed to know his real name was later retracted. According to researchers his identity still remains unknown.
Arne Beurling was a Swedish mathematician and professor of mathematics. In 1940 the mathematician broke the German code used for strategic military communications. This accomplishment is considered by many to be one of the greatest achievements in the history of cryptography. Using only teleprinter tapes and cipher text, he deciphered the code that the Germans believed impossible to crack in just two weeks. Beurling created a device that enabled Sweden to decipher German teleprinter traffic passing through Sweden from Norway on a cable. When Beurling was asked how he broke the code he replied, “A magician does not reveal his secrets”.
Interesting Fact: Beurling code breaking allowed Swedish authorities to know about Operation Barbarossa (The codename for Nazi Germany’s invasion of the Soviet Union) before it occurred.
James Black was an Arkansas blacksmith and the creator of the original Bowie knife designed by Jim Bowie. Bowie was already famous for knife-fighting from his 1827 sandbar duel. But his killing of three assassins in Texas and his death at the Battle of the Alamo made him, and the blacksmith’s knife, legends. Black’s knives were known to be exceedingly tough yet flexible. Black kept his methods for creating the knife very secret and did all of his work behind a leather curtain. Many claim that Black rediscovered the secret to producing Damascus steel which is a type of steel used in Middle Eastern sword making from 1100 to 1700 that could cut through lesser quality European swords. The original techniques to make James Black’s knife cannot be duplicated even today. Black died on 22 June 1872 in Washington, Arkansas.
Interesting Fact: In 1839 shortly after Black’s wife’s death, he was nearly blinded when his father-in-law and former partner broke into his home and attacked him with a club, having objected to his daughter having married Black years earlier. After the attack Black was no longer able to continue in his trade.
Edward Leedskalnin was a Latvian emigrant to the United States and amateur sculptor. Leedskalnin single-handedly built the monument known as Coral Castle in Florida and is also known for his unusual theories on magnetism. Leedskalnin was only 5-ft. tall and weighed 100-lbs and aligned many of his stones astronomically and integrated them into a grand architectural plan based on mathematical and astronomical data. Leedskalnin used only simple tools to cut, trim and assemble over 3 million pounds of dense coral blocks to build his castles. When asked, “How did you build the Castle?” he replied, “It’s not difficult really the secret is in knowing how.” When Leedskalnin moved his Coral Castle ten miles away to Homestead Florida he asked the trucker to look away when it came time to load and unload the coral stones. Leedskalnin died from malnutrition due to stomach cancer in 1951 at the age of 64 without ever revealing his secret.
Interesting Fact: Billy Idol wrote and recorded the song “Sweet Sixteen” and filmed the video in the Coral Castle. The song was inspired by the story of Leedskalnin’s former love, Agnes Scuffs, who is believed to be the main reason Leedskalnin built the Coral Castles.
Johann Bessler was born in Zittau, Germany and built a machine that he claimed was self-moving. By 1717, he had convinced thousands of people, from the ordinary to the most prominent that he had indeed discovered the secret of a self-sustaining mechanism. The machine underwent numerous tests and passed rigorous inspections. It was made to do heavy work for long periods, and in an official test it ran continuously for 54 days. The internal design of the machine was always closely guarded by its inventor. Plagued by paranoia and a nasty temper and with no patent laws to protect him Bessler destroyed the machines in a fit of anger and took his secret to the grave. The true motive power behind Bessler’s demonstrations, and the energy source which moved the wheel’s internal weights still remain unexplained. Obviously a machine like this violates the law of conservation of energy, which states that energy can never be created or destroyed but it should then be asked how did Bessler fool so many people for so many years?
Interesting Fact: Recently, a series of coded features has been discovered among various papers published by Bessler. He constructed a variety of codes from very simple to very complex which would in time could be collected together to reveal his secret. Some of these codes have been solved but many others remain un-deciphered.
Benjamin Franklin is one of the most well known Founding Fathers of the United States. Other talents included author, printer, satirist, political theorist, politician, scientist, inventor, civic activist, statesman and diplomat. In 1730 Franklin acknowledged an illegitimate and only son William. He was raised by his father Ben and his common-law wife Deborah Rea. Some of the many theories speculated is that the reason for not disclosing William’s mother is the couple was not married when William was born and Franklin wanted to take all of the blame so as not to allow any dishonor to come to Deborah. Other evidence suggests his mother was a prostitute. William’s mother official identity still remains unknown.
Interesting Fact: In 1752 when William was 21 he assisted his father in the famed kite experiment. William later became a steadfast Loyalist throughout the Revolutionary War despite his father’s role as one of the most prominent Patriots during the conflict, a difference that tore the two apart.
Stradivari was an Italian crafter of stringed instruments such as violins, cellos, guitars and harps. For centuries scientists and historians have tried to figure out Stradivari’s secret to his instrument making. Recently modern research tools and devices such as scanning lasers are aiding researchers in testing the theory that the careful shaping of belly and back plate, in order to “tune” their resonant frequencies could be an important factor. Glues and varnishes used by Stradivari have also been analyzed extensively and could also attribute for the sound and quality of his instruments. Experts concede there remains no consensus on the single most probable factor to explain the superior sound of the Stradivarius and most likely it is some combination of all, and something not yet recognized.
Interesting Fact: It is estimated that Stradivari made around 1100 instruments. Today only 650 instruments remain, including approximately 500 violins.

Great list! It seems like such a waste and loss that some of these great secrets for metal, stone and wood working should be lost to all of humanity due to one person’s stubborn nature. Think of the good that a perpetual motion machine (if that’s what it truly was, and I’m dubious) would be.
Very cool list!
This site has pics of #4 lifting the coral with a “tripod”.

Whoops! Here’s the proper link…

Awesome list Blogball, I love these mystery ones! I love them even though they drive me nuts because we don’t know the answers… *sigh* haha..
great list
Very interesting list, though a little maddening. I’ll be wondering about them all day, especially #9. On #8, though, unless I’m mistaken, the mystery is who she was? The man made them promise not to tell? It’s an odd one to me, because if they had been just anybody, you’d barely remember them now. The second the guy says “swear not to tell”, it becomes this huge mystery. It’s one of those things that you know for a fact would be a complete disappointment if you learned the truth.
Wonderful list, Blogball. I learned some things, and found some things to delve into. That makes a perfect list for me.
Congratulations!
Probably the best list published on this site in a while.
Very well done. Thank you.
Fascinating list, but the genius of Nikola Tesla has been overlooked, yet again. Much of his work with electricity and magnetism is still not understood by today’s scientists. His mysterious “black box” is one of his most interesting experiments that has never been explained. This is a very interesting list, but it is incomplete without the enigmatic genius Tesla.
I agree that Tesla is missing. Thomas Edison saw his as a threat and a rival but could never equal nor replicate much of Tesla’s work. We always hear about Edison, while Tesla is often thought of as the name of a bad 80′s hair band.
66) I think a lot of the mystery is why the heck did they care so much about their identities not being revealed?
oops that was for flibbertigibbet I didn’t make that clear
Number 1 has ALWAYS interested me. I am a Luthier and used to work for a family owned luthier buisness in Hilo Hawaii called Melody and Harmony Creations. Though now retired we sold Ukuleles and guitars world wide. Some of the ones I created have even been used in live concerts in Japan which I think is pretty cool. ^_^ We made the Pulelehua Ukuleles and guitars. We also fixed a wide range of stringed intstruments. I can say from experinece in crafting such tings from blocks of wood that the shape, density, glue and laquer all play a vital part in sound quality. As does wood choice, bone choice, strings and virtually ever part of the stringed instrument help it to produce a different and unique to that 1 instrument kind of sound. It baffles me at the quality produced and time involved in making these instruments in his life (1644-1737). It may take YEARS for 1 instrument to be finished to the masters liking. Not to mention they did not have the benifit of power tools!! It is time honored labours of love like those in the arts that are slowly wilting out of our societies. I feel everyone should learn how to create something they never thought they could at least once in thier life. You will appreciate the learning of it more then you can anticipate right now. ^_^ Whod’a thunk an Alaskan girl would make Ukuleles after all? See ANYONE can be ANYTHING if the try hard enough….. well almost anything…. I still haven’t sprouted a cats tail. **giggles**
I read this list expecting Tesla to come in at #1. Needless to say I was a bit disappointed. Nevertheless a nice little list.
Thank you Listversers for all the positive comments! I really learned a lot of neat stuff from doing the research on these people and some others that I left off. Yan Ohayon , Festus , Tickles & Ben, believe it or not I almost included Tesla but the more I read about the “black box” to power his car the more it seemed like it was more of a tall tale than fact. http://en.wikipedia.org/wiki/Tesla_electric_car
There may be other Tesla secrets that are legitimate but I couldn’t find anything particular that still remains unknown from all of his great work.
Poor Tesla …he seems to always get left off of the Listverse lists.
Very interesting list. I wondered about Tesla as well but did he take his secrets with him or did someone take his inventions and papers after his death?
Some pretty interesting people…
But where on earth was Fermat?
Once again, Blogball comes through with a fascinating and well-researched list. Nice job.
brilliant list…so compelling…so enlightning
My violin professor plays a Stradivari and it is one of the most beautiful things i have ever heard in my life! One interesting explanation I have heard is that the mini ice age that was going on during that time period caused trees to grow slower and thus yield denser wood.
I already knew about the Ben Franklin thing, considering “William” is thought to be my greatx7grandfather on my mom’s side, William Hewson’s wife’s son with Ben Franklin. This would make Ben Franklin my greatx8grandfather, or however you say that. I think that’s pretty cool.
I’m happy to see Edward Leedskalnin made the list. Of all the mysteries I know of, his intrigues me the most. This man more than likely knew the secret to how the pyramids were really built.
Fascinating list!
8 and 5 are the best in my opinion. Number 8 could involve a woman of very high status. I would have liked to know James Black’s secret too. Always wanted to cut through other people’s swords. But really, would be awesome to know.
Ok, ok already. This is a good list but not the best list ever. I admit the last few list have been a little bland but just because a bunch of some weird stuff is printed doesn’t make blogball a genius.
dole, just for that I’m taking the secret I used to create this list to the grave.
This list is awesome, I think the most interesting one was Arne Beurling.
But you missed one HUGGGGGGGGE one:
Grigori Rasputin. I mean how did he heal Alexi? How did he not die after consuming enough cyanide to kill 4 men, shot 4 times, thrown into an icy river, stabbed and beaten?
The way he lived and the way he died to day is still a mystery
Fascinating list!
blogball,
That was funny. Have you been waiting for just the right time to use that line. You know that “kill ‘em with kindness” bit gets me every time. Perhaps you are smarter than I thought.
Rasputin might not have known.
7 and 9 don’t belong on this list. they are potentially not even secrets taken to the grave at all if the person allegedly holding the secret has no recollection of who he or she was. The rest of the list was interesting though.
Actually, the strativari instruments were believed to have been made with wood that had breen preserved from the ice age.
You forgot James Smithson, the British scientist who, in his will, awarded his entire estate and fortune to become the Smithsonian Museum. The mystery is why he left his fortune to America. He had never traveled to the United States and had no correspondence with anyone there.
Interesting list. You should have included the man in the Iron mask perhaps :3
great list jfrater..more! more! ü
The story of Jerome creeps the hell out of me.
Great list! As others have said, this kind of list is what attracted me to listverse in the first place.
I would add Lee Harvey Oswald. Only he knows if he acted alone.
Very similar to #5 was F.J. Richtig, the village blacksmith of Clarkson Nebraska. He had a method of making knives that allowed him to hammer them through nails, pieces of an anvil, parts of rail road ties, etc. and they would still remain razor sharp. This was featured in a Ripley’s believe it or not book.
Since he had no apprentice and his son was uninterested in his fathers craft the secret died with Richtig.
There are still a lot of his knives floating around the midwest still in use. His kitchen knives were rather crude in appearance but his custom made hunting knives are considered quite valuable and sought after.
Great list.
Fascinating list, really makes you wonder about how much information has been lost to humanity over the centuries. It’s a little sobering to think that there are still some relatively simple concepts and ideas out there that we still have no idea about.
My favourite entry was the perpetual motion machine. I’m naturally sceptical about the existence of such a device, but IF it did exist…wow. The amount of theory regarding conservation of energy that would be rendered invalid is simply mind boggling.
“The original techniques to make James Black’s knife cannot be duplicated even today.”
If this is implying that modern steel still can’t compare to James Black’s steel he created, it is completely false. The tensile strength and ductility of today’s steel is not even a comparison.
i wish i’d read this when we did a crossword the other day. I could for the life of me remember who was considered to make the best violins!
My favorite list ever…
Bootlicker: Some would say if Lee Harvey Oswald acted at all. It was never published, but my US history teacher in high school wrote a book that talks about all the theories that surround JFK’s death. I never got a chance to read it but would have liked to.
Cool list! I think I saw one of the remaining Stradivari violins in a museum when I visited Spain over the summer. It was a beautiful instrument (from what I could tell on the other side of the glass), but I had no idea it was so shrouded in mystery.
This is an awesome list! I have three to contribute:
1) Who was Beethoven’s Immortal Beloved. Maynard Solomon, in his wonderful biography, makes a convincing argument that it was Antonie Brentano…but it is something we will never know for certain.
2)Mozart’s death. His cause of death is still disputed by scholars and historians. One fact is known, Salieri had nothing to do with it (The play and movie, great as they are, Amadeus, are not historically accurate).
3)Tchaikovsky’s death. It was always believed that he died of cholera…but there is much evidence to support that he committed suicide because he was blackmailed to do so. Apparently evidence of his homo*****uality had leaked to some important figures in Russia and he was given two choices…death or exile from the land that he adored so much. His brother, Modest, was his biographer and is believed to have created the scenario for his brother’s death…although there are over 10 extremely different accounts of when Tchaikovsky drank the so-called fateful glass of unboiled water. Clearly there was a cover up!
I hope there will be a part 2 of this list soon!!
Nice list, what about the man who could turn water into wine.
What a completely fabulous list. I love a good enigma.
Great list. Very interesting
Angelo Faticoni never did reveal the secret in how he became the Human Cork and he received his buoyancy.
Agatha Christie never told anyone about her missing 11 days.
Alexander Hanos from Craig, Colorado never told anyone his secret recipe for the salad dressing.
Thomas Jefferson Beale’s remaining two ciphers remains a mystery.
James Michener’s heritage remains unknown (he could be part Jewish or part African-American or part Muslim or part Russian or part Irish or part Native American or part Mexican or part Puerto Rican or part Spanish or part Portugese, or part Greek or probably not Oriental or part German or part French or part Swedish or part Norwegian or part Finnish or part Danish or part Bulgarian or part Belgian or part Dutch.)
Absolutely Fascinating!
Great list! But like a pp mentioned, I won’t be able to stop thinking about these for a while … frustrating! But in a good way ^_~
As an addendum to number 7, Eddie Vedder of Pearl Jam wrote a song about The Leatherman, appropriately entitled “Leatherman”. It never made it onto any album, but was B-side of a single released in 1998.
They play live from time to time and has become a fan favorite of sorts among the more loyal followers of the band.
Here’s a link to one of the live performances of the song:
http://listverse.com/history/top-10-fascinating-secrets-taken-to-the-grave/
And here’s the lyrics:
I heard about a man to whom I may be related.
He’s leatherman.
Died a long time ago in the 1880′s. Leatherman. Leatherman.
Covered with leather but it wasn’t tight.
Underneath a moon in the woods at night.
Making the rounds ten miles a day. Once a month they’d spot him and here’s what they’d say.
“Here he comes. He’s a man of the land. He’s leatherman
Smile on his face. Axe in his bag.
He’s leatherman. Leatherman. Leatherman.”
Comes out of the caves once a day to be fed.
He wasn’t known to stay much but, “Thanks for the bread.”
So, modern day I walk my way with my jacket faded just like a man of leather to whom I may be related.
Rolled cigarette for which he’d ask for a light.
Appear to be an animal. Yet, so polite.
Making the rounds ten miles a day. Once a month they’d spot him and here’s what they’d say
“Here he comes he’s a man of the land. He’s leatherman
Smile on his face. Axe in his hand.
He’s leatherman. Leatherman. Leatherman.”
Leatherman. Leatherman.
Shake his hand. He’s leatherman. Bake some bread. He’s leatherman.
Shame he’s dead. I saw his bed.
It’s all that’s left of leatherman. Leatherman.
Give me some skin Leatherman.
Sorry, try this link for the song:

Re: Johann Bessler
Perpetual motion machine solution? There was a GUY inside the machine!
what about einsteins last words? he might have revealed the secrets of the universe and we’ll never know cause his nurse didn’t speak german
Ahh Jerome. Growing up in Nova Scotia, where Digby County is located (and the province should have been listed in the fact), we’ve all heard about this story.
I went from the most recent list (top badasses), hit the stumble button, and here I am! What a coinci-dink.
This is really an excellent list with “secrets” I didn´t know.
Here is another secret:
Naples’ Cappella Sansevero is a Baroque explosion mourning the body of Christ, who lies on a soft pillow under an incredibly realistic veil. It’s also the personal chapel of Raimondo de Sangro, an eccentric Freemason. The monuments to his relatives have a second purpose: to share the Freemason philosophy of freedom through enlightenment.
Giuseppe Sammartino’s Veiled Christ.
Giuseppe Sammartino’s Veiled Christ.
Study the incredible Veiled Christ in the center. Carved out of marble, it’s like no other statue I’ve seen (by Giuseppe “Howdeedoodat” Sammartino, 1753). The Christian message (Jesus died for our salvation) is accompanied by a Freemason message (the veil represents how the body and ego are an obstacle to real spiritual freedom). As you walk from Christ’s feet to his head, notice how the expression of Jesus’ face goes from suffering to peace.
Raimondo de Sangro lies buried at the far (altar) end. An inventor, he created the deep-green pigment used on the ceiling fresco. The inlaid M.C. Escher-esque maze on the floor around de Sangro’s tomb is another Freemason reminder of how the quest for knowledge gets you out of the maze of life.
To the right of the altar, the statue of Despair struggles with a marble rope net (carved out of a single piece of stone), symbolic of a troubled mind. The Freemason symbolism shows how knowledge — in the guise of an angel — frees the human mind. On the opposite side of the altar from Despair, a veiled woman fingers a broken plaque, symbolizing…something.
It was never found out how the veil – whioch covers the completed marble figure – nor the net were done. some think it could have done by draping a real veil over the figure and petrifying it with chemicals, but the sculptor never revealed his secret.
