Today is the birthday of Thomas Alva Edison, prolific American inventor whose ideas and inventions including the lightbulb, the phonograph, and motion pictures, changed the world forever. I don't know who said it, but the home page of a website dedicated to Edison has a great and fitting quote about this remarkable man:

"He led no armies into battle, he conquered no countries, and he enslaved no peoples... Nonetheless, he exerted a degree of power the magnitude of which no warrior ever dreamed. His name still commands a respect as sweeping in scope and as world-wide as that of any other mortal - a devotion rooted deep in human gratitude and untainted by the bias that is often associated with race, color, politics, and religion."

Happy birthday to the Wizard of Menlo Park!!

Les Paul, inventor of the first solid body electric guitar died today in New York. His guitars and musical inventions influenced entire generations of musicians, including the Beatles, U2, and Led Zeppelin. Paul, who was considered a country and jazz guitarist continued to play music well into his nineties, playing Monday nights at the Iridium club on Broadway in New York City. Paul invented a number of technical innovations - such as multitrack tape recording and overdubbing - that are still used in the music industry today. Listen to the above YouTube clip of one of Paul's first uses of multitrack recording on a 1950 song called "How High the Moon" in which he recorded and overdubbed 12 guitar tracks with 12 tracks of his wife Mary Ford's singing. Legend has it that Mary sang into a microphone hanging over the kitchen sink at home.

Tesla's birthday

by mdr on Jul. 10th, 2009

Nikola Tesla, inventor, mechanical engineer, and electrical genius was born on this day in 1856 in the village of Smiljan, Croatia. We had a recent posting about Tesla here on the Buzz if you want to learn more about him. And you should want to learn more. Life today just wouldn't be the same without his ideas and inventions. And I can't think of a more fitting way to honor his genius than this video of two Tesla coils playing the Super Mario Brothers theme song. Happy birthday Nikola!

I recently (and literally) stumbled upon a web page about this remarkable man from the 17th century. His name was Matthias Buchinger, and despite being born without hands, legs or thighs, this guy managed to live a full and amazing life with no less than 4 wives (!?), and fathering something like 11-14 children depending on the source. But even more incredible was how - despite his severe physical deformations - Buchinger was able to rise above Nature’s challenges and become an accomplished musician, inventor, artist, model-in-a-bottle builder, and magician.

Born in Anspach, Germany in 1674, he was the youngest of nine children, and became widely known as “The Little Man from Nuremburg” performing his feats of wonder across much of Great Britain and Europe. Buchinger was only 29 inches tall, and for hands had "two excrescences which grew from his shoulder-blades, like fingers without nails" but his skills in magic, marksmanship, and music were legendary. He played several musical instruments, some of which he invented himself, was accomplished at skittles (bowling), and could dance a hornpipe as well as anyone. He was also a talented calligrapher. His engraving skills are evident by the self-portrait to the right. Hidden within his curls are seven psalms and the Lord’s Prayer written in tiny letters. Buchinger lived much of his adult life in England and Ireland, and performed before King George and many of Europe’s royalty. He died in Cork, Ireland in 1732.

I don’t know about you but I find Buchinger quite inspiring. You can read more about this human marvel in the links below.

In 1901, inventor and electrical visionary Nikola Tesla began building a laboratory near New York’s Long Island Sound complete with a gigantic 18-story radio tower that he hoped would not only broadcast wireless communications to the world but also supply free electricity for everyone. His grand schemes, however, never really got off the ground. Before the year was out Guglielmo Marconi (using seventeen of Tesla’s patents) would claim to send the first radio signal across the Atlantic, and soon after, Tesla’s investors - including steel magnate J. P. Morgan - began to lose faith in the project and withheld further funding. Eventually mounting debts, lawsuits and loss of patent income began to take their toll on Tesla and his visionary plans.

Known as Wardenclyffe, the site was designed by noted architect Stanford White. It operated for a few years in the early 1900s, even serving as the inventor’s main laboratory for a time. But by mid-decade Tesla himself abandoned the site, and for years it sat unoccupied falling to ruin. Inner machinery and equipment were salvaged and sold to satisfy monetary obligations, and the massive tower was dismantled for scrap during World War I leaving only its foundation. But the main building still stands today and, despite its dilapidated state, has the distinction of being the only remaining worksite of the brilliant Gilded Age inventor.

Now a group of Tesla devotees are pushing for the site to be preserved and designated as a historical site and memorial to a man they say is worthy of a monument.

Tesla contributions were certainly monumental. The Serbian-born inventor held over 700 patents and introduced to the world such things as fluorescent lighting, the first remote controlled robot, x-ray photographs, and wireless communications. One invention, the Tesla coil, is still used in today’s radios and television sets and other electrical devices. One of his greatest contributions, the development of alternating electrical current (AC) technology, went against his former employer Thomas Edison's big push for direct current (DC). The threatened Edison went so far as to hire a man to electrocute dogs, old horses, and even a rogue elephant(!) to show the public the dangers of AC current. But AC’s superior technology proved more efficient and cheaper, and near the end of his life, Edison admitted Tesla had been right.

Tesla was a bit of a showman when it came to promoting his inventions and theories, often portraying himself in composite photographs sitting peacefully in a display of electric current. During the height of his career he was a wealthy and dapper household name who hobnobbed with the scientific, artistic, and political elite of his day, and had several laboratories in the New York area. In the late 1890s he set up a lab in Colorado Springs to supposedly “transmit a radio signal from Pikes Peak to Paris”. With funding from Colonel John Jacob Astor (who later went down with the Titanic), Tesla built an 80-foot tower on the prairie for that very purpose. Whether or not he achieved his objective remains a mystery, but he and his assistant did manage to put on quite a lightshow for Colorado Springs residents. Reportedly, the tower discharged a high-voltage flurry of 145-foot sparks in every direction that subsequently blew out the power for the entire town. After nine months of experiments, he abandoned the lab and returned to New York to continue his experiments at Wardenclyffe. The Colorado Springs facility was eventually torn down and sold for scrap and no sign of it remains today,

A consortium of science enthusiasts, preservationists, and plain old fans of Tesla’s genius want the Wardenclyffe facilities preserved as a national monument and museum. The group includes Tesla biographer Marc Siefer who helped pen a letter to President Obama asking for the necessary funds to purchase the 10,000-square foot brownstone structure and surrounding acres from the Belgium-based Agfa Corp, which is eager to sell the property to soften the effects of the present economy.

But Siefer and his colleagues think Tesla’s many accomplishments warrant its preservations. For one thing the group contends it was Tesla - not Marconi - who was the true inventor of wireless radio. The issue of who owned the patents for radio broadcast has gone back and forth since the early 20th Century. In 1904 the US Patent Office ruled in favor of Marconi for the patents even though it had ruled in Tesla’s favor in the prior year. Marconi’s many powerful investors may have been the reason for this. After Marconi won the Nobel Prize in 1909 the furious Tesla sued him for infringement and lost again. But in 1943, the US Supreme court proclaimed Tesla was the inventor (probably because the Marconi Company was suing the US government for infringement of the same patents). Unfortunately, for Tesla, this final designation came two months after his death.

Even today, Tesla still seems to elude proper recognition, but Marc Seifer and his colleagues hope to change that by acquiring and preserving Wardenclyffe, a site they say has great historic significance as the last remaining trace of the eccentric inventor’s once grand vision.

“It’s hugely important to protect this site,” Seifer said. “He’s an icon. He stands for what humans are supposed to do — honor nature while using high technology to harness its powers.”

French engineer and chemist Georges Claude died on May 23, 1960. In 1902, he invented the neon light (obviously near and dear to our hearts!) by applying electricity to a sealed tube of neon gas. Used to promote a Packard car dealership in Los Angeles, the first neon signs in the US cost $24,000.

Engineer James B. Eads, known for his bridge over the Mississippi at St. Louis, was born on May 23, 1820. The bridge wasn't his only claim to fame, though. He also invented a boat and diving bell that allowed him to run a salvage operation and made him a fortune. He also built ironclad warships for use during the Civil War, and a year-round navigation channel for New Orleans.

Elijah McCoy
Elijah McCoy

It's an annual tradition here at The Science Museum. Every February for Black History Month we roll out a panel honoring Black Americans in science. And every February, Gene complains that the panel contains an error.

Part of the panel pays tribute to Elijah McCoy. The son of runaway slaves, McCoy studied engineering and went on to invent many devices, including a lubricator for railroad engines.

The panel also cites Elijah's invention as the origin of the phrase "the real McCoy." Unfortunately, that does not seem possible:

  • The phrase first appears in Scotland, in the form "the real McKay," in 1856, when Elijah was only 12 years old.
  • The phrase changed from "McKay" to "McCoy" around 1908 — more than 30 years after Elijah patented his invention.
  • The lubricators were not sold under the McCoy name until 1920, well after the phrase had become established.
  • Elijah's name was not connected to the phrase until 1985.

Make no mistake — Elijah McCoy's inventions were a boon to railroading. It's only right that we honor his contribution to engineering. But, as a science museum, we really need to be more careful with the facts. It's a small thing, but as a label writer, mistakes like this bug me.

(NOTE: I am writing this post from the wilds of mid-Michigan. I haven't seen the panel this year — it's possible that the error has been corrected. If so, I will amend this post.)
