Isaak Pomeranchuk
The family moved from his birthplace, Warsaw, first to Rostov-on-Don in 1918 and then Donbas in the town of Rubizhne in 1923, where his father worked at a chemical plant.In 1943, he transferred to Laboratory No.2 under Igor Kurchatov as part of the Soviet project to develop nuclear weapons.Rudolf Peierls was consoled by the fact that it was "very clever Pomeranchuk" – and no-one else – who corrected his 1/T law for heat conduction in high-temperature condensed matter physics.His work in the 1940s was dominated by neutron research and his manuscript with Akhiezer was the basic guide for Soviet nuclear reactor construction.[1] In 1950, Pomeranchuk received an order from Joseph Stalin to go to Arzamas-16, located in the closed city of Sarov, Nizhny Novgorod region, to work on Soviet nuclear weaponry.
