Hans Reichenbach

Born in Hamburg in 1891, Hans Reichenbach studied philosophy, mathematics, and physics in Germany and became one of the central figures in the movement later known as logical empiricism. He taught in Berlin, where he was associated with the Berlin Circle, and wrote on topics ranging from relativity and probability to causation and the direction of time.

After leaving Nazi Germany, he continued his career abroad and eventually taught at the University of California, Los Angeles. His books and essays aimed to connect philosophy closely with the methods and findings of modern science, and he became especially known for clear, rigorous thinking about how scientific knowledge works.

Reichenbach died in 1953, but his influence has lasted well beyond his lifetime. Readers interested in the foundations of science, the meaning of probability, or the logic behind physical theories often find his work both historically important and surprisingly fresh.
