  1. Audio Timeline By: Eric Sutton Teacher: Mr. Hardin

  2. 1877 • Thomas Alva Edison, working in his lab, succeeds in recovering Mary's Little Lamb from a strip of tinfoil wrapped around a spinning cylinder.

  3. 1878 -1887 • 1878 The first music is put on record: cornetist Jules Levy plays "Yankee Doodle." • 1888 Edison introduces an electric motor-driven phonograph

  4. 1881 • Clement Ader, using carbon microphones and armature headphones, accidentally produces a stereo effect when listeners outside the hall monitor adjacent telephone lines linked to stage mikes at the Paris Opera

  5. 1887 -1888 • 1887 Emile Berliner is granted a patent on a flat-disc gramophone, making the production of multiple copies practical. • 1888 Edison introduces an electric motor-driven phonograph.

  6. 1895 • Marconi successfully experiments with his wireless telegraphy system in Italy, leading to the first transatlantic signals from Poldhu, Cornwall, UK to St. John's, Newfoundland in 1901.

  7. 1898 • 1898ValdemarPoulsen patents his "Telegraphone," recording magnetically on steel wire

  11. 1912 -1913 • 1912 Major Edwin F. Armstrong is issued a patent for a regenerative circuit, making radio reception practical. • The first "talking movie" is demonstrated by Edison using his Kinetophone process, a cylinder player mechanically synchronized to a film projector

  12. 1916 • A patent for the superheterodyne circuit is issued to Armstrong. • The Society of Motion Picture Engineers (SMPE) is formed. • Edison does live-versus-recorded demonstrations in Carnegie Hall, NYC.
