Steinberg, formulations of phage growth, recombination and mutation. Foss and others, the demonstration of two functional pathways for genetic recombination in wild-type budding yeast. These studies utilized the method of density gradient centrifugation that was developed for the test of the semiconservative model of DNA replication. Stahl and others, the mutual dependence of DNA replication and genetic recombination.

Stahl and others, the discovery and analysis of the genetic element, Chi, that stimulates nearby genetic recombination in bacteria. Murray and others, the determination, by genetic methods, of the direction of mRNA synthesis on cotranscribed pairs of genes. Foss and others, demonstrations of genetic linkage circularity and its relation to genetic heterozygosis. Meselson, the demonstration of semiconservative DNA replication. With his partner, Jette, he shares five children (plus spouses) and eight grandchildren, of whom five are adopted. Surviving are Andy Stahl, a forester and political activist, and Emily Morgan, a hairdresser and shop owner. Stahl and his wife Mary (married in 1955) raised two boys and a girl. Since his retirement in 2001, he lives with Jette and four llamas in Eugene, where he continues to submit research papers and participates in University of Oregon governance. Stahl's research was undertaken in association with numerous colleagues, especially his long-tem associates Jean M. He undertook sabbatical studies in Cambridge, UK, Edinburgh, Jerusalem, and Cambridge, Massachusetts. He taught various genetics courses at Oregon and presented phage courses in America, Italy and India. In the succeeding years, his research involved the phages T4 and Lambda and the budding yeast, Saccharomyces cerevisiae, with his primary focus on genetic recombination. įor one year, Stahl served on the zoology faculty at the University of Missouri in Columbia, Missouri before accepting, in 1959, a position in the new Institute of Molecular Biology at the University of Oregon in Eugene. That study produced strong support for the semiconservative model proposed by Jim Watson and Francis Crick. With Meselson, he studied DNA replication in Escherichia coli. With Steinberg, he undertook mathematical analyses of T4 growth, mutation, and genetic recombination. He subsequently turned his attentions to collaborations with Charley Steinberg and Matt Meselson. In 1955, he undertook postdoctoral studies with Giuseppe Bertani (in the Phage group) at Caltech ( Pasadena) with the aim of learning some bacterial genetics. In 1956, he received a PhD in biology for his work with Doermann on the genetics of T4 phage. (Gus) Doermann at the Cold Spring Harbor Biological Laboratory. His interest in genetics was cemented in 1952 by his introduction to bacterial viruses ( phages) in a course taught by A. In 1951, he was awarded an AB degree in biology from Harvard College, and matriculated in the biology department of the University of Rochester. Stahl, like his two older sisters, graduated from the public schools of Needham, a Boston suburb.
