On Wednesday, August 15th, the inventor of the 555 timer Hans Camenzind passed away. Camenzind was a Swiss emigre analog guru who invented one of the most successful circuits in electronics history and introduced the concept of phase-locked loop to IC design. The 555 timer was commercialized by Signetics in 1972, and" it went on to become one of the most successful in the industry's history. The device, used in oscillator, pulse-generation and other applications, is still widely used today. Versions of the device have been or are still made by dozens of major semiconductor vendors, including Texas Instruments, Intersil, Maxim, Avago, Exar, Fairchild, NXP and STMicroelectronics." -Brian Fuller, EE Times

Camenzind was 78 years old and was an emeritus professor of electrical engineering at San Francisco State University.
