'''Emory Leon Chaffee''' (April 15, 1885 – March 8, 1975) was an American [[physicist]]. He was a professor at [[Harvard University]] from 1911 to 1953.<br />
<br />
Chaffee was born in [[Somerville, Massachusetts]]. He studied [[electrical engineering]] and received his bachelor's degree from [[MIT]] in 1907. Afterward he made further studies at the [[Harvard University]] and took his master's degree and his [[Ph.D.]]<br />
<br />
He was made an instructor in electrical engineering in 1911 and got a position as assistant professor of physics in 1917. In 1923, he became an [[associate professor]] and a professor in 1926. He was appointed [[Rumford Chair of Physics|Rumford Professor of Physics]] in 1940, and Gordon McKay Professor of [[applied physics]] in 1946. Chaffee became chairman of the Department of Engineering Sciences and Applied Physics from 1949 till 1952.<br />
<br />
Chaffee was awarded the [[IEEE Medal of Honor]] in 1959. He was best known for his work on thermionic [[vacuum tube]]s. In 1911, he invented the concept of the [[Chaffee Gap]] which was a way of producing continuous oscillations for radio transmissions, and in 1924, he started to work on controlling weather, using aircraft to break up clouds with electrically charged grains of sands.<br />
<br />
Chaffee died in [[Waltham, Massachusetts|Waltham]], [[Massachusetts]].<br />
