Biography
He was born on 19 April 1880 in Southington, Connecticut.[1]
He majored in Greek and after taking one undergraduate course in physics, graduated from Yale University. He taught languages at
In 1914 Hull joined the General Electric Research Laboratory (GERL) in Schenectady, New York and remained there until his retirement in 1949.[1]
During 1916, Hull began investigation into the use of magnetic control of
He died on 22 January 1966 at the age of 85 in Schenectady, New York.[1][2]
Dynatron
He invented the
Magnetron
By 1920 his research led to his invention of the
Gas-filled electron tubes
During the 1920s, Hull also was a major contributor to the development of gas-filled electron tubes at the GERL. He discovered how to protect thermionic cathodes from rapid disintegration under ion bombardment. This discovery enabled the successful development of hot-cathode thyratrons (gaseous triodes) and phanotrons (gaseous diodes).
