## Summary
Tadeusz Reichstein was a Polish-Swiss chemist (1897–1996) who co-discovered vitamin B2 (riboflavin) and developed the Reichstein process for steroid synthesis, revolutionizing pharmaceutical research. He was a pioneer in biochemistry and a recipient of the Nobel Prize in Physiology or Medicine (1950).

## Biography
- Born: July 8, 1897, in Wrocław, Poland
- Nationality: Polish, Swiss
- Education: Doctorate from the University of Basel (1921)
- Known for: Co-discovery of vitamin B2 and development of the Reichstein process for steroid synthesis
- Employer(s): ETH Zurich, University of Basel
