Today at Berkeley Lab

In Memoriam: Steve Lewis

Steve Lewis, formerly with the Lab’s Engineering Division, passed away on May 26 after a three-year battle with cancer. He was 70 years old. Lewis worked at the Lab from 1979 to 1984, then again from 1986 to 2002. He was the lead for control system upgrades at the Bevatron, and also worked on BaBar and the Spallation Neutron Source Injector System. He is survived by his wife, two brothers, two sons and two daughters, and four grandsons. A memorial will be held on Saturday, June 11, from noon to 5 p.m. at the Lewis home (2 Biehs Court, Oakland, 94618).


  1. I’ve known Steve professionally, as a fellow cyclist and as a friend just about my whole career at the laboratory. Although he graduated with a PhD in physics from Yale in 1969, it was while working at the Indiana University Cyclotron facility that Steve was drawn to accelerator control system engineering which was to become his career. He talked fondly about those days and the opportunity he had to work on all aspects of the cyclotron controls from hardware to software. From Indiana, to the Bevatron, to SNS, to NIF and finally LCLS Steve loved using new technology to solve problems. Steve was a strategic thinker and mentor in his field becoming a key innovator and teacher in an international collaboration for accelerator software know as EPICS (Experimental Physics and Industrial Control System). When I visited during his illness his lifelong enthusiasm still came through when he talked about his work.

    At the Bevatron in the 1970’s Steve developed his passion for bicycling. Along with Roger Dwinell and other folks from the Bevatron, he was part of the core group of LBL noon-time cyclists. When I joined the group I always looked forward to our conversations on these rides through the Berkeley Hills. After he left LBNL, Steve would often bike over from his house in Oakland on his new bike to meet the group (except on Fridays when he visited his grandkids).

    When I talk to people at the laboratory that knew him, it’s that energy and passion which he brought to his work and the rest of his life that everyone mentions first. Steve will be missed.
