  • Emory Leon Chaffee was an American physicist and a former professor at Harvard University from 1911 to 1953. 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. 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 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. Chaffee was awarded the IEEE Medal of Honor in 1959. He was best known for his work on thermionic vacuum tubes. In 1911 he invented the concept of the Chaffee Gap which was a way of producing continuous oscillations for long-distance telephone transmissions and in 1924 he started to work on controlling weather, using aircraft to break up clouds with electrically charged grains of sands. Chaffee died in Waltham, Massachusetts.
  • Emory Leon Chaffee war ein US-amerikanischer Physiker. Chaffee studierte Elektrotechnik am MIT und erhielt 1907 seinen Bachelor. Anschließend setzte er sein Studium in Harvard fort, wo er seinen Master erwarb und 1911 promovierte. Während seiner Doktorarbeit fand er erstmals eine Methode kontinuierliche, kohärente elektromagnetische Oszillationen von mehr als 100 MHz zu erzeugen und zur Radiotelefonie anzuwenden. Er wurde Übungsleiter, stieg 1917 zum Assistenzprofessor auf, 1923 zum Associate Professor und 1926 schließlich zum ordentlichen Professor. 1924 wurde er Pionier auf dem Gebiet der Wetterkontrolle. Er versuchte vom Flugzeug aus Wolken mit geladenen Sandkörner zu impfen. 1940 übernahm er die Rumford Professur für Physik, 1946 die Gordon McKay Professur für Vakuumphysik. Er wurde Direktor des Cruft Laboratoriums und Kodirektor des Lymanlaboratoriums. Von 1949 bis 1952 war er Vorsitzender der Fakultät für Ingenieurwesen und Angewandte Physik. Er arbeitete auch auf den Gebieten der Vakuumröhren und der Optik. Er war Autor zweier Bücher und Koautor eines anderen.
