| Biochemist, born in Czernowitz, S Czech Republic. He studied at Vienna, Yale, Berlin, and Paris, and worked at Columbia University, New York City, from 1935. His pioneer work on nucleic acids showed that the DNA of an organism has a composition characteristic of the organism; and his work on the ratio of bases present in DNA (the Chargaff rules) provided a fundamental contribution to the double helix structure for DNA advanced in 1953. |
