Gertrude Neumark
Gertrude Fanny Neumark , also: Gertrude Neumark Rothschild (born April 29, 1927 in Nuremberg ; † November 11, 2010 in Rye (New York) ) was an American physicist and pioneer in the development of light emitting diodes (LEDs).
Life
In 1935 the family fled the Nazi persecution of Jews to the United States . Gertrude Neumark began her studies at Barnard College and then studied chemistry at Radcliffe College , where she received a Masters , and then at Columbia University , where she earned her Ph.D. in 1951. received his doctorate.
From 1952 she worked in research for companies in the electrical industry, first in the Sylvania Research Laboratories in Baysie, NY and from 1960 to 1985 in the research department of Philips in Briarcliff Manor, New York. In 1982 she was elected a Fellow of the American Physical Society . From 1982 to 1985 she was visiting professor for material sciences at Columbia University and received the chair for materials science here in 1985. In 1990 she received the endowed professorship Howe Professor of materials science and engineering .
Patents
Neumark has been researching the optical capabilities of certain semiconductors since the 1980s . Her results led her to hold patents in semiconductor technology ( wide-bandgap semiconductor technology ) that enable the development of LEDs. In 2006 a settlement was reached with a number of LED manufacturers that they had sued for infringing their patents.
In 2008 she filed a complaint with the United States International Trade Commission to prohibit the import of devices that were equipped with unlicensed LEDs according to her patent. After the commission began an investigation, the companies concerned reached an agreement with Neumark on a license and approximately US $ 27 million in royalties.
She was married to Henry Rothschild, but used her maiden name in academic circles and for publications.
