From The New York Times:
"Gertrude Neumark Rothschild, whose research helped improve light-emitting and laser diodes now used in many cellphones, flat-screen televisions and Blu-ray disc players, and who waged a successful patent-infringement battle against some of the world’s biggest electronics companies that yielded tens of millions of dollars in settlements and licensing fees, died on Nov. 11 in Rye, N.Y. She was 83."
From The Fu Foundation School of Engineering and Applied Science at Columbia University:
"Gertrude Neumark graduated summa cum laude from Barnard College in 1948, received a Master of Science degree in chemistry from Radcliffe in 1949, and, in 1951, received a Ph.D. in chemistry from Columbia’s Graduate School of Arts and Sciences. Prior to joining the Columbia faculty, Dr. Neumark worked in industry at Sylvania Research Laboratories (1952-1960) and at Philips Laboratories from 1960-1985. She was elected a Fellow of the American Physical Society in 1982. From 1982-1985 Dr. Neumark was also an Adjunct Professor at Columbia. She started teaching and conducting research here full-time from 1985. She was appointed Howe Professor of Materials Science and Engineering in July 1999. In 2005, the Henry and Gertrude Rothschild Professorship was established at Columbia University in recognition of her contributions to science."
