TV and LCD pioneer
Life Fellow, 82; died 11 April
Lechner made pioneering contributions to the development of LCD and advanced television technology.
He was an electrical engineer for 30 years at RCA’s David Sarnoff Research Center (now SRI International), in Princeton, N.J. Lechner joined the company in the late 1950s, devoting much of his first decade with RCA to the development of home video-recording and TV cameras. In the mid-1960s, Lechner worked with another RCA researcher, IEEE Fellow George Heilmeier, to develop the first active-matrix LCD television screen. (Heilmeier died in May.)
When RCA sold its LCD interests in 1976, Lechner shifted his research focus to advanced TV systems and high-definition TV. He retired in 1987 as vice president of RCA’s advanced video systems group and became a consultant, serving on standards committees and as an expert witness in patent litigation cases.
He received the 1996 David Sarnoff Gold Medal and the 2001 Progress Medal from the Society of Motion Picture and Television Engineers, both for contributions to the technologies essential to modern TV systems. In 2000, the Advanced Television Systems Committee established the Bernard J. Lechner Outstanding Contributor Award in his honor. He was also honored with the 2011 IEEE Jun-ichi Nishizawa Medal for conceiving the principle of active-matrix LCDs.
He received a bachelor’s degree in electrical engineering from Columbia University.
