Gennady Gorelik (born 1948, Lviv) is a research fellow at the Center for Philosophy and History of Science, Boston University. A physicist by education and historian by occupation, he published ten books and many articles on popular science and history of science, including in-depth biographies of 20th-century Russian physicists, Matvei Bronstein, Andrei Sakharov, and Lev Landau.
In his biography of Sakharov, he provides the documentary explanation of Sakharov's metamorphosis from a secret father of the Soviet H-bomb to most prominent advocate of human rights in the Soviet Union.
In 1995, he received a Guggenheim Fellowship.
