    Description

    John Bardeen - Co-Inventor of the Transistor/The Only 2x Nobel in Physics/Signed Card
    John Bardeen (1908-1991) - American engineer and physicist. He is the only person to be awarded the Nobel Prize in Physics twice: first in 1956 with William Shockley and Walter Brattain for the invention of the transistor; and again in 1972 with Leon N. Cooper and John Robert Schrieffer for a fundamental theory of conventional superconductivity known as the BCS theory.
    The transistor revolutionized the electronics industry, making possible the development of almost every modern electronic device, from telephones to computers, and ushering in the information Age. Bardeen's developments in superconductivity—for which he was awarded his second Nobel Prize—are used in nuclear magnetic resonance  spectroscopy (NMR) and medical magnetic resonance imaging (MRI).
    5” x 3” index card signed in ballpoint pen, adding the date “2/3/79”. Very fine.
    This is from an extensive 50 year collection covering all categories, that was built from the 1940’s through the 1980’s.
