Transistor and is ubiquitous in modern electronic systems. Julius Edgar Lilienfeld patented a field-effect transistor in 1926 but it was not possible to actually construct a working device at that time. The first practically implemented device was a point-contact transistor invented in 1947 by American physicists John Bardeen, Walter Brattain, and William Shockley. The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things. The transistor is on the list of IEEE milestones in electronics, and Bardeen, Brattain, and Shockley shared the 1956 Nobel Prize in Physics for their achievement.
General Electric Research Laboratory bulb filament, providing a more durable and long-lasting light filament than the existing technology. "The invention secured GE's technological leadership in the market and epitomized the role of the GE research lab — bringing innovation to the marketplace." But, that work was still an improvement on existing technology and nothing entirely new. In the coming years, GE scientists earned two Nobel Prizes in chemistry and physics. In 1932, Irving Langmuir won the Nobel Prize in chemistry for his work on surface chemical reactions which helped him develop the gas-filled light bulb in 1916. After patenting many inventions, Langmuir developed his
