1890–1975
A Berkeley physicist and philosopher of science, he was remembered for sharp logical thinking and a deep commitment to teaching. His work moved between physics, philosophy, and the history of science, giving him an unusually wide intellectual range.

by Victor F. (Victor Fritz) Lenzen, Robert P. Multhauf
Born in San Jose, California, on December 14, 1890, he studied first in engineering before turning toward philosophy and theoretical questions at the University of California. Sources from the Online Archive of California and the American Institute of Physics describe a career shaped by both physics and philosophy, along with an early interest in marine engineering that hints at the curiosity behind his later academic work.
He spent much of his professional life at the University of California, Berkeley, where he became known as a professor of physics with a strong interest in the philosophy of science. An in memoriam notice from the University of California remembers him as a rigorous thinker and devoted teacher, and archival records show the breadth of his papers, including lectures, manuscripts, and research notes.
Lenzen died in Oakland on July 18, 1975. I could confirm the main outlines of his life and career from university and archival sources, but I could not verify a suitable portrait image from the pages available during this search, so no profile image is included.
