Emory Leon Chaffee

Emory Leon Chaffee ( born April 15, 1885 in Somerville, Massachusetts, † March 8, 1975 in Waltham, Massachusetts ) was an American physicist.

Chaffee studied electrical engineering at MIT and received his bachelor's degree in 1907. He then continued his studies at Harvard, where he earned his master's degree and doctorate in 1911. During his doctoral work, he was first a method continuous, coherent electromagnetic oscillations of more than 100 MHz to generate and apply for radio telephony. He was instructor, rose in 1917 as Assistant Professor in 1923 and to Associate Professor in 1926, to full professor.

In 1924, he became a pioneer in the field of weather control. He tried to vaccinate clouds with charged sand grains from an airplane.

In 1940 he took over the Rumford Professor of Physics, 1946, the Gordon McKay Professor of vacuum physics. He became director of the Cruft Laboratory and co-director of Lymanlaboratoriums.

From 1949 to 1952 he was chairman of the Faculty of Engineering and Applied Physics. He also worked in the fields of vacuum tubes and optics.

He was the author of two books and co-author of another.
