Frisch, Otto Robert
The Austrian Otto Robert Frisch (1904 - 1979), son to a painter, was a nuclear physicist.
During the Christmas holiday in 1938, he visited his aunt Elise Meitner in Sweden. While there, his aunt received the news that Otto Hahn and Friedrich Wilhelm Strassmann in Berlin had discovered that the collision of a neutron with a uranium nucleus produced barium as one of its byproducts. He and his aunt hypothesized that uranium had split in two, and estimated the energy released. He coined the term fission to describe the process.
During World War II he worked on the Manhattan Project.
