Franklin W. Stahl Biography
Franklin W. Stahl, in collaboration with Matthew Meselson, discovered direct evidence for the semiconservative nature of deoxyribonucleic acid (DNA) replication in bacteria. In experiments, Stahl and Meselson showed that when a double stranded DNA molecule is duplicated, the double strands are separated and a new strand is copied from each "parent" strand forming two new double stranded DNA molecules. The new double stranded DNA molecules contain one conserved "parent" strand and one new "daughter" strand. Therefore, the replication of a DNA molecule is semiconservative: it retains some of the original material while creating some new material. The understanding of the semiconservative nature of DNA in replication was a major advancement in the field of molecular biology.
Franklin William Stahl, the youngest of three children, was born on October 6, 1929, in Boston, Massachusetts, to Oscar Stahl, an equipment specialist with New England Telephone and Telegraph, and Eleanor Condon Stahl, a...

Franklin "Frank" Stahl was born in Boston. He received a B.A. from Harvard University in 1951. Stahl then went to the University of Rochester for graduate work.
While finishing up his Ph.D., Stahl attended a molecular biology course at Woods Hole. The course was being taught by James Watson and Francis Crick, and it was here that Stahl met Matthew Meselson. As they both tell it, during a break in the course, Meselson introduced himself to Stahl who was sitting under a big tree drinking and selling gin and tonics. At the time, Meselson was a graduate student at the California Institute of Technology; he was interested in exploring new methods of experimentation. Stahl had the experience and the math to help Meselson design these experiments. They hit it off right away and made plans for Stahl to do post-doctoral work at Caltech.
In 1957, Stahl and Meselson developed the technique of density gradient centrifugation and used it to prove that DNA was replicated in a semi-conservative way, as predicted by Watson and Crick in their 1953 paper. Meselson and Stahl's paper appeared in 1958.
In 1959, Stahl accepted a position at the University of Oregon where he is now a distinguished professor of Molecular Biology. His current research interest is on the mechanisms of g
