Chu is noted for his work on the fundamental limitations for small antennas, also known as [Chu–Harrington limit](/source/Chu%E2%80%93Harrington_limit). ==Biography== Lan Jen Chu was born on August 24, 1913, in [Huai'an](/source/Huai'an) in the [Jiangsu](/source/Jiangsu) province of [China](/source/China).{{cite journal | title = Biography - Lan Jen Chu | journal = IRE Transactions on Microwave Theory and Techniques | volume = 6 | issue = 3 | pages = 249 | publisher = IEEE | date = July 1958 | doi = 10.1109/TMTT.1958.1124553 | bibcode = 1958ITMTT...6..249.}} He graduated from [Shanghai Jiao Tong University](/source/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. Chu was with the [Radiation Laboratory](/source/Radiation_Laboratory) at MIT from 1942 to 1946 and with the Department of Electrical Engineering from 1947 to 1973.{{cite web | title = MIT Museum Nomination | publisher = [Massachusetts Institute of Technology](/source/Massachusetts_Institute_of_Technology) | url = http://museum.mit.edu/nom150/entries/1297 | accessdate = 16 January 2014 | archive-date = April 21, 2018 | archive-url = https://web.archive.org/web/20180421165809/http://museum.mit.edu/nom150/entries/1297 | url-status = dead}} He died on July 25, 1973, in [Lexington, Massachusetts](/source/Lexington%2C_Massachusetts), and was survived by his wife Grace Feng and three children.{{cite news |title=Dr. Lan Jen Chu, 59, M.I.T.
