 Julius Marmur

Julius Marmur (March 22, 1926 – May 20, 1996, aged 70) was an American molecular biologist who made significant contributions to DNA research.His discovery, while working in the laboratory of Paul Doty at Harvard University, that the denaturation of DNA was reversible (DNA hybridization) and depended on salt- and GC-content, had a major impact on how scientists thought about DNA, and how DNA could be handled "in vitro."
