Bernard Roizman

Roizman's research interests focused on the herpes simplex virus, particularly on regulation of viral genes and on the use of site-specific mutagenesis to study viral gene function. In 1999 he was involved in an inventorship dispute with a member of his research group, whose lawsuit was ultimately successful.

Roizman joined the faculty at Johns Hopkins after graduation, and later spent a year as a visiting scientist at the Institut Pasteur in Paris. When he returned to the United States he joined the faculty at the University of Chicago in 1965. He served as department chair from 1985 to 1988. He was one of several prominent virologists involved in the founding of the American Society for Virology and organized a key meeting in Chicago that led to the society's establishment.

Bernard Roizman (born April 17, 1929) is an American scientist born in Romania. He is the Joseph Regenstein Distinguished Service Professor of Virology in the Departments of Microbiology and Molecular Genetics and Cell Biology at the University of Chicago.

Roizman was born in Chisinau, Romania in 1929. As he later recalled, his early life was "shaped by World War II" and the hardships his family endured as war refugees after being displaced in 1941 by the German invasion of the Soviet Union. The family eventually made their way to the United States in 1948, where they settled in Philadelphia. Roizman received a scholarship to attend a Pennsylvanian college and enrolled at Temple University, from which he received his bachelor's and master's degrees. He subsequently attended the Johns Hopkins School of Public Health where he received his Sc.D. in 1956.
