Lee De Forest - Wikipedia, the free encyclopedia

Lee de Forest (August 26, 1873 – June 30, 1961) was an American inventor with over 180 patents to his credit. De Forest invented the Audion, a vacuum tube that takes relatively weak electrical signals and amplifies them. De Forest is one of the fathers of the "electronic age", as the Audion helped to usher in the widespread use of electronics. He is also credited with one of the principal inventions that brought sound to motion pictures.

He was involved in several patent lawsuits and spent a substantial part of his income from his inventions on the legal bills. He had four marriages and 25 companies. He was defrauded by business partners and he defrauded business partners. He was indicted for mail fraud, but was later acquitted.

He was a charter member of the Institute of Radio Engineers. DeVry University was originally named DeForest Training School by its founder Dr. Herman A. DeVry, who was a friend and colleague of De Forest's.

This was supposed to go in the lee de forest article but this website seems to be a bit on the slow side anyways lee de forest is considered one of the fathers of the electronics age because he invented and patented his design of the vacuum tube

Deforest also filed the first patent for "sound on film."

J. J. Thomson - Wikipedia, the free encyclopedia

Sir Joseph John "J. J." Thomson, OM, FRS[1] (18 December 1856 – 30 August 1940) was a British physicist and Nobel laureate. He is credited with discovering electrons and isotopes, and inventing the mass spectrometer. Thomson was awarded the 1906 Nobel Prize in Physics for the discovery of the electron and for his work on the conduction of electricity in gases.

Joseph John Thomson was born in 1856 in Cheetham Hill, Manchester, England. His mother, Emma Swindells, came from a local textile family. His father, Joseph James Thomson, ran an antiquarian bookshop founded by a great-grandfather from Scotland (hence the Scottish spelling of his surname). He had a brother two years younger than him, Frederick Vernon Thomson.[2]

His early education took place in small private schools where he demonstrated great talent and interest in science. In 1870 he was admitted to Owens College. Being only 14 years old at the time, he was unusually young. His parents planned to enroll him as an apprentice engineer to Sharp-Stewart & Co., a locomotive manufacturer, but these plans were cut short when his father died in 1873.[2] He moved on to Trinity College, Cambridge in 1876. In 1880, he obtained his BA in mathematics (Second Wrangler and 2nd Smith's prize) and MA (with Adams Prize) in 1883.[3] In 1884 he became Cavendish Professor of Physics. One of his students was Ernest Rutherford, who would later succeed him in the post. In 1890 he married Rose Elisabeth Paget, daughter of Sir George Edward Paget, KCB, a physician and then Regius Professor of Physic at Cambridge. He had one son, George Paget Thomson, and one daughter, Joan Paget Thomson, with her. One of Thomson's greatest contributions to modern science was in his role as a highly gifted teacher, as seven of his research assistants and his aforementioned son won Nobel Prizes in physics. His son won the Nobel Prize in 1937 for proving the wavelike properties of electrons.

Joseph John Thomson invented the vacuum diode which has greatly improved the field of electronics and using his work will give more insight into the people who made great changes in the field

Thomson also discovered the electron which is a key part to the fundamentals of electronics
