Biography

Erwin Chargaff is recognized among Jewish contributors to Science & Medicine — Biochemist who formulated Chargaff's rules of DNA base composition, a key step toward the double-helix model.

How & why

Chargaff was a biochemist whose analysis established 'Chargaff's rules' — that in DNA the amount of adenine equals thymine and guanine equals cytosine — a key clue that guided Watson and Crick to the double-helix model. He was born into a Jewish family in Czernowitz and emigrated to the United States, working for decades at Columbia University.
