Frank John Kerr (8 January

1918 – 15 September 2000) was made contributions to human understanding

of the galactic structure of the Milky Way. Born in St Albans to Australian parents, Kerr returned with his

family to Australia after the completion of World War I. He received degrees in physics at the University of Melbourne and

an MA in astronomy from Harvard University (1951).

In 1940, Frank had joined the Commonwealth Scientific and Industrial Research laboratory in Sydney, Australia under the mentorship of Joseph Lade Pawsey. He pioneered the use of the magnetron, and also studied superrefraction. In Australia in late 1951, Kerr used a specially

built 36-foot transit telescope, the largest dish of its kind in

Australia, and started mapping the Magellanic Clouds, discovering considerable amounts of neutral hydrogen and an extended envelope around both

clouds. From 1954 to 1955, Kerr was a member of the team that determined the

rotation of the Magellanic Clouds and their masses. Kerr coined the term

"galactic warp" to refer to the distorting effect of the Magellanic Clouds' gravity on the shape of our own galaxy. Over the years he

worked with various astronomers, including Colin Gum and Gart Westerhout. From 1966 to 1979, he was a visiting, then

full, professor of astronomy at the University

of Maryland, College Park. Kerr was the Director of the Astronomy

Program during the mid-1970s. From 1978-1985, Kerr then acted as the Provost

of the Mathematical and Physical Sciences and Engineering Division at the

University of Maryland. He

died of cancer at Silver Spring, Maryland.
