Hans R. Camenzind, 1934 - 2012, resident of Los Altos, born and raised in Zurich, Switzerland, Hans came to the US in 1960 with his wife for an adventurous few years. As a young linear electronics engineer, he enjoyed being part of the growing semiconductor industry and they decided to make the US their permanent home. He worked for several of the important semiconductor companies of the era, including Transitron, Tyco Semiconductor, P.R. Mallory's Research Lab, and Signetics. In 1971, as the father of four young children, he left the security of stable employment to found InterDesign, a company specializing in semi-custom integrated circuit design. One of the circuits he designed was the 555 timer, which turned out to be the most successful integrated circuit ever produced and is still widely used. After selling InterDesign in 1978, he founded Array Design, where he continued his passion for designing a variety of circuits. In addition to the many articles he authored, he published 4 books on integrated circuit design, Circumstantial Evidence, a book on God and religion under the pseudonym John Penter, and Much Ado about Almost Nothing, a history of electricity and electronics. Hans also enjoyed remodeling houses, working with wood, and doing projects with his grandchildren in his workshop. He is survived by his wife Pia, his daughter Sue (Erol Kirelik), his sons Robert (Amy), Peter (Lisa), Tim (Marie) and nine grandchildren, Christopher, Danielle, Katie, Tommy, Emilee, Hannah, Sean, Corianna, and Cassandra whom he all loved and was very proud of. A private family service was held on August 17th. A remembrance of Hans' life will be held at 2 pm on September 9th, in the Shoup Park Garden House in Los Altos. Friends and colleagues are welcome. In lieu of flowers, the family would prefer donations in Hans' memory to the Computer History Museum. To RSVP and for information on donations, please see camenzind.org/hans/.
