Fermilab News, Feb. 11, 2020, by Steve Koppes

“Fermilab has lost one of its giants. Award-winning engineer and physicist Alvin Tollestrup, who played an instrumental role in developing the Tevatron as the world’s leading high-energy physics accelerator at Fermi National Accelerator Laboratory and founding member of the Collider Detector at Fermilab collaboration, died on Feb. 9 of cancer. He was 95.

“Alvin Tollestrup, who passed away on 9 February at the age of 95, was a visionary. I joined his group at Caltech in 1960. Alvin had helped build Caltech’s electron synchrotron, the highest energy photon-producing accelerator at the time. But he thought more exciting physics could be performed elsewhere, and managed to get approval to run an experiment at Berkeley Lab’s Bevatron to measure a rare decay mode of the K+ meson.”

Alvin Virgil Tollestrup
From Physics Today, June 2020, by Chris Quigg and Mel Shochet

“Alvin Virgil Tollestrup, a key figure in the development of Fermilab, notably the creation of the Tevatron, succumbed to cancer on 9 February 2020 in Warrenville, Illinois. Born on 22 March 1924 in Los Angeles, Alvin moved with his family when he was six to Logan, Utah, where his grandfather’s position as a psychology professor helped them weather the Depression.”
There young Alvin had a basement laboratory with a chemistry set and electronic components.
