I ran across this photo with the caption "Churchill, Roosevelt, & Stalin: Freemasons." It is well known and accepted that both Winston Churchill and Franklin D. Roosevelt were Freemasons. Churchill was a member of Studholme Lodge No. 1591, England and Roosevelt was a member of Holland Lodge No. 8, New York. So the question is whether Joseph Stalin, the Premier of the Soviet Union who allied with the United States and Great Britain during World War II was also a member of the fraternity.
Since the 1950s, Stalin has frequently been cited as a Freemason. However, there is no record that Stalin was a Mason. It would not have been possible for Stalin to join a regular lodge even if he had desired admission. As a condition for membership, Masons must profess a belief in a Supreme Being, and Joseph Stalin was an avowed athiest.
