Lithography lost one of its own on July 12 with the death of Frits Zernike Jr. to Parkinson’s disease. Here is his obit from the New York Times:

Born and educated in Groningen, the Netherlands. A physicist with Perkin-Elmer Corp., Silicon Valley Group and Carl Zeiss, and first manager for Dept. of Energy’s Extreme Ultraviolet Lithography Program. Survived by his wife of 49 years, Barbara Backus Zernike, children Frits III, Harry, and Kate, daughter- and son-in-law Jennifer Wu and Jonathan Schwartz, and three grandchildren: Frits and Nicolaas Schwartz and Anders Zernike. Memorial service will be 3pm Thursday, July 28, at Essex Yacht Club, Novelty Lane, Essex, CT. Donations in his memory may be made to Dance for Parkinson’s, c/o NMS, 100 Audubon St, New Haven, CT 06510, or Community Music School, P.O. Box 387, Centerbrook, CT 06409.

Here is an excerpt from a post I made to this blog on February 27, 2009 concerning Frits:

“It was seven years ago that SPIE approached me with the idea of creating a major SPIE award in microlithography. I agreed to head up the effort, and gathered together a committee of other lithographers to establish the award process. Someone on the committee suggested naming the award after Frits Zernike, for three reasons. First, no major optical award had been named in his honor, even though the scientific contributions of this Nobel prize winner are legion. Second, the name has high recognition in the optical lithography community due to the ubiquitous use of the Zernike polynomial for describing lens aberrations. The third reason is more personal – Zernike’s son, Frits Zernike Jr., worked for many years in the field of lithography at Perkin-Elmer and later SVG Lithography before retiring. Some of us on the committee knew him, and when contacted he was very supportive of an award named for his father.”
