On 22 Oct 1925, Julius Edgar Lilienfeld (a Polish1 professor in Germany) patented the field-effect transistor (FET). [ARN98][ROS95] The much later point-contact transistor (Bell Labs, 1948) was a dead end: [LIL4] today, almost all of the billions of trillions of transistors in our computers and smartphones are FETs of the Lilienfeld type. [EMM13]Before the above issues became widely known, three Bell Labs researchers shared the Nobel Prize for the transistor, which should have been awarded to Lilienfeld. [ARN98]As of 2025, there is no reasonable doubt that the inventor of the transistor is Julius Edgar Lilienfeld. Since the invention of the transistor, computers have become much faster through integrated circuits (ICs) gathering many transistors on the same microchip.
