Drahoslav Lím : biography

September 30, 1925 - August 22, 2003

Drahoslav Lím (born September 30, 1925 in Czechoslovakia; died August 22, 2003 in San Diego, California)US Social Security Death Index, reported at http://ssdi.rootsweb.ancestry.com/cgi-bin/ssdi.cgi was a Czech chemist. He invented polyhydroxyethylmethacrylate, the synthetic material used for contact lenses (hydrogel).

This work was later published in NatureWichterle O, Lim, D. "Hydrophilic gels for biological use".

When he returned to Czechoslovakia he was persecuted for political reasons and was not allowed to work in his specialisation. In 1979, he was allowed to emigrate to the United States. There Lím worked on materials for artificial kidneys and continued with research on polymers. He was both a professor at the University of California, San Diego and the de facto founder of the Revlon Materials Research Center. At the latter he led a team of scientists who researched tinting technologies for hydrogel contact lenses, materials for intraoccular lenses, and formulations for nail enamel. He was awarded over 150 patents.

Although the academic community recognises the importance of his inventions, the Czech public almost never hears his name.
