Question: A point-contact transistor was the first type of solid-state electronic transistor ever constructed, it was developed by which American physicist, electrical engineer, and research scientist?
Sentence (from "John Bardeen"): John Bardeen ( ; May 23, 1908 – January 30, 1991) was an American physicist and electrical engineer, the only person to have won 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.
Relevant evidence: Yes
