Soviet theoretical physics titan who founded the 'Landau school' and pioneered quantum fluid dynamics

He rated physicists on a logarithmic scale by achievement: class 1 was Bohr, Heisenberg, Dirac. Einstein alone was class 0.5. He once placed himself at 2.5, later promoting himself to 1.5.

Soviet theoretical physicist. He founded the 'Landau school' in Kharkov, selecting disciples through his rigorous Theoretical Minimum exam, and pioneered condensed matter physics with his theories of superfluidity and Fermi liquids. His Course of Theoretical Physics with Lifshitz set the global textbook standard.

The long-hidden manager of crewed spaceflight

On April 12, 1961, Yuri Gagarin slept soundly before humanity's first spaceflight. Kerimov, monitoring the cosmonaut's sleep via bed sensors, spent a far more anxious night than the man about to ride the rocket.

His career began in World War II inspecting Katyusha rockets and gathering intelligence on the German V-2. He served on the State Commissions for Sputnik 1 and the Vostok programme, then chaired the State Commission for crewed flights from 1966 to 1991, twenty-five years in which he gave the final launch approval for every Soviet crewed mission. He was the administrative gatekeeper of Soviet crewed spaceflight's golden age, from Salyut and Soyuz-Apollo to Mir, yet his identity was kept strictly secret until perestroika.
