Milislav Demerec

Milislav Demerec (January 11, 1895 – April 12, 1966) was a Croatian&mdash;American geneticist, and the director of the Cold Spring Harbor Laboratory (CSHL) from 1941 to 1960, recruiting Barbara McClintock and Alfred Hershey.

Demerec was born and raised in Kostajnica (then Austria-Hungary, now Croatia). He attended College of Agriculture in Križevci, graduating in 1916. He worked at Krizevci Experiment Station, and then attended the College of Agriculture in Grignon, France after World War II. He emigrated to the United States for graduate studies in 1919.

In 1919 he statred his PhD at Cornell University, his work was on maize genetics and was supervised by Rollins A. Emerson. He completed his PhD in 1923 and took up a research position at the Carnegie Institution of Washington's Department of Genetics Cold Spring Harbor Laboratory. He completed work from his PhD, showing that ten different alleles could cause albinism in maize kernels, the at the advice of C. W. Metz he began work on the genetics of the plant Delphinium and the fruitfly Drosophila virilis studying mosaicism.

He became a prominent Drosophila researcher and established the Drosophila Information Service newsletter in 1934 with Calvin Bridges. In 1936 he was made the assistant directory of the Department of Genetics, and the director in 1941 following the retirement of Albert Blakeslee, he was also made director of the Biological Laboratory of the Long Island Biological Association making him the director of both Cold Spring Harbor laboratories.

In the 1940s the direction of Demerecs research changed to the genetics of bacteria and their viruses after a symposium given by Max Delbrück. During World War II ha used his knowledge of bacterial genetics to increase the yield from the Penicillium bacteria. Following the war he continued to work on bacterial genetics and the problem of antibiotic resistance in E. coli, Salmonella, and Staphylococcus. In 1946 he was elected to the National Academy of Sciences, and in 1947 became the founding editor of Advances in Genetics, the first journal to review the finding of modern genetics. In the 1950s he served on the genetics panel of the National Academy of Sciences' Committee on the Biological Effects of Atomic Radiation. In 1952 he elected to the American Philosophical Society.

Following his retirement from CSHL, he took a position at the Brookhaven National Laboratory, working there until 1965. In 1966 he served briefly as research professor at Long Island University, until he died on April 12 1965.
