During the 1940s, the funds and bank transactions made during the Philosophers' pact to end World War II, known as the Philosophers' Legacy, was stored on a microfilm by Boris Volgin, the Philosophers' main accountant, as a means to ensure that the Soviet Union got the vast sum of money. By the 1960s, Boris' son, GRU colonel Yevgeny Borisovitch Volgin, obtained the microfilm containing the Philosophers' Legacy, which the governments of China and America attempted to steal for themselves. Eventually, in September 1964, the microfilm made its way to America, with the Chinese gaining a fake microfilm from their agent.
