This was an experiment by William Dickson to put sound and film together either in 1894 or 1895. Unfortunately, this experiment failed because they didn't understand synchronization of sound and film. The large cone on the left hand side of the frame is the "microphone" for the wax cylinder recorder (off-camera). The Library of Congress had the film. The wax cylinder soundtrack, however, was believed lost for many years. Tantalizingly, a broken cylinder labeled "Violin by WKL Dickson with Kineto" was catalogued in the 1964 inventory at the Edison National Historic Site. In 1998, Patrick Loughney, curator of Film and Television at the Library of Congress, retrieved the cylinder and had it repaired and re-recorded at the Rodgers and Hammerstein Archive of Recorded Sound, Lincoln Center, New York. Since the Library did not possess the necessary synchronizing technology, Loughney - at the suggestion of producer Rick Schmidlin - sent multi-Oscar winner Walter Murch a videotape of the 17 seconds of film and an audiocassette of 3 minutes and 20 seconds of sound with a request to marry the two. By digitizing the media and using digital editing software, Murch was able to synchronize them and complete the failed experiment 105 years later. This 35mm film was generously made available to the Internet Archive by Walter Murch and Sean Cullen. Dec 18, 2011 4:08 PM

He is frequently cited as one of the most important contributors to the birth of commercial electricity and is best known for his many revolutionary developments in the field of electromagnetism in the late 19th and early 20th centuries. Tesla’s patents and theoretical work formed the basis of modern alternating current (AC) electric power systems, including the polyphase system of electrical distribution and the AC motor, with which he helped usher in the Second Industrial Revolution. Alpha waves in the human brain are between 6 and 8 hertz. The wave frequency of the human cavity resonates between 6 and 8 hertz. All biological systems operate in the same frequency range. The human brain’s alpha waves function in this range and the electrical resonance of the earth is between 6 and 8 hertz. Thus, our entire biological system – the brain and the earth itself – work on the same frequencies. If we can control that resonate system electronically, we can directly control the entire mental system of humankind. Nikola Tesla was born on July 10, 1856 in Smiljan, Lika, which was then part of the Austo-Hungarian Empire, region of Croatia. His father, Milutin Tesla was a Serbian Orthodox Priest and his mother Djuka Mandic was an inventor in her own right of household appliances. Tesla studied at the Realschule, Karlstadt in 1873, the Polytechnic Institute in Graz, Austria and the University of Prague. At first, he intended to specialize in physics and mathematics, but soon he became fascinated with electricity. He began his career as an electrical engineer with a telephone company in Budapest in 1881. It was there, as Tesla was walking with a friend through the city park that the elusive solution to the rotating magnetic field flashed through his mind. With a stick, he drew a diagram in the sand explaining to his friend the principle of the induction motor. Before going to America, Tesla joined Continental Edison Company in Paris where he designed dynamos. While in Strassbourg in 1883, he privately built a prototype of the induction motor and ran it successfully. Unable to interest anyone in Europe in promoting this radical device, Tesla accepted an offer to work for Thomas Edison in New York. His childhood dream was to come to America to harness the power of Niagara Falls. Young Nikola Tesla came to the United States in 1884 with an introduction letter from Charles Batchelor to Thomas Edison: “I know two great men,” wrote Batchelor, “one is you and the other is this young man.” Tesla spent the next 59 years of his productive life living in New York. Tesla set about improving Edison’s line of dynamos while working in Edison’s lab in New Jersey. It was here that his divergence of opinion with Edison over direct current versus alternating current began. This disagreement climaxed in the war of the currents as Edison fought a losing battle to protect his investment in direct current equipment and facilities.
