In the middle of the picture below is Bill Arnold, a familiar face to many lithographers. He was head of lithography at AMD for many years, become the head of a technology development group (TDC) at ASML, as well as Chief Scientist (I think I have the title right) at ASML. He always gives some of the best talks at the SPIE Advanced Lithography conference, and is a senior editor at JM3. In the field of lithography, he is one of the smartest guys around.
To Bill’s right is his sister, Frances Arnold, and to his left is Donna Strickland, former president of OSA who Bill got to know while he was president of SPIE. The occasion for the fancy attire? They are all in Stockholm last month at the Nobel Prize Award Ceremony, where Frances Arnold received the Nobel Prize in Chemistry, and Donna Strickland received the Nobel in Physics.
Smart definitely runs in the Arnold family.
