Abram Ioffe

After graduating from Saint Petersburg State Institute of Technology in 1902, he spent two years as an assistant to Wilhelm Röntgen in his Munich laboratory.

[citation needed] After 1906, Ioffe worked in the Saint Petersburg (from 1924 Leningrad) Polytechnical Institute where he eventually became a professor.

Ioffe organized this conference, then published a journal report, disclosing to researchers throughout the world the science and technology that would ultimately be called radar.

[6] When the Soviet atomic bomb project began in 1942, Ioffe was asked to lead the technical effort, but refused the job on the grounds that he was too old.

Ioffe asked Ernest Rutherford to accept Pyotr Kapitsa to Cavendish Laboratory at the University of Cambridge.
