Lev Petrovich Pitaevskii

An obituary for theoretical physicist Lev Petrovich Pitaevskii who died on Aug 23, 2022 in Rovereto, Italy, from the consequences of a fall, compounded by age-related health issues is presented. He was known across the physics community for his encyclopedic scientific knowledge; important discoveries in low-temperature physics; contributions to the understanding of superfluidity in helium-3 and helium-4; and the theories of Bose-Einstein condensates, van der Waals forces, and low-density ionospheric plasma. Pitaevskii will also be remembered as a coauthor, with Lev Landau and Evgeny Lifshitz, of the world-famous 10-volume series Course of Theoretical Physics.
