Biography
Lan Jen Chu was born on August 24, 1913, in Huai'an in the Jiangsu province of China.[1] He graduated from Shanghai Jiao Tong University in 1934 with a Bachelor of Science degree in electrical power, and went on to receive Master of Science and Doctorate of Science degrees in electrical engineering from MIT in 1935 and 1938, respectively.[1] Chu was with the Radiation Laboratory at MIT from 1942 to 1946 and with the Department of Electrical Engineering from 1947 to 1973.[2] He died on July 25, 1973, in Lexington, Massachusetts, and was survived by his wife Grace Feng and three children.[3][4]
During World War II, Chu supervised research at MIT of many special antennas for use in radar and telecommunication applications.[1] In 1945, he acted as a United States Secretary of War and headed the advisory specialist group to United States Armed Forces in China. For his services, he received the President's Certificate of Merit.[3] He has also authored three technical books, two of which were with Richard Adler and Robert Fano in the area of electromagnetics.[5] Lan Jen Chu was a fellow of the American Physical Society and the Institute of Radio Engineers,[1] as well as a member of Academia Sinica.[6]
