Joshua Lederberg, who won the Nobel Prize in 1958, died last Saturday from pneumonia. While in graduate school, he discovered that bacteria could reproduce sexually and he named the rings of DNA that E. coli exchanged "plasmids." He also led the way for molecular biology and biotechnology: "Josh was one of the most creative scientists of our times," Stanford's Stanley Cohen tells the Los Angeles Times. Lederberg was 82.
