Lan Jen Chu was born on August 24, 1913, in Huai'an in the Jiangsu province of China.cite-ref-mtt-bio-1-0[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.cite-ref-mtt-bio-1-1[1] Chu was with the Radiation Laboratory at MIT from 1942 to 1946 and with the Department of Electrical Engineering from 1947 to 1973.cite-ref-museum-nom-2-0[2] He died on July 25, 1973, in Lexington, Massachusetts, and was survived by his wife Grace Feng and three children.cite-ref-nytimes-3-0[3]cite-ref-4[4]

During World War II, Chu supervised research at MIT of many special antennas for use in radar and telecommunication applications.cite-ref-mtt-bio-1-2[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.cite-ref-nytimes-3-1[3] He has also authored three technical books, two of which were with Richard Adler and Robert Fano in the area of electromagnetics.cite-ref-mitpress-5-0[5] Lan Jen Chu was a fellow of the American Physical Society and the Institute of Radio Engineers,cite-ref-mtt-bio-1-3[1] as well as a member of Academia Sinica.cite-ref-6[6]
