Osip Minor

On 22 March 1889 he participated in a prisoners' uprising in Yakutsk and was condemned to death by hanging, but the sentence was commuted to hard labour for life.

He was affiliated with the mainly Jewish Socialist-Revolutionary Workers' Party for the Political Liberation of Russia, organised by Mark Natanson.

During the First World War Minor took a Defencist position, which put him at odds with the PSR leader Viktor Chernov and with his old associate Natanson.

Among his close friends was Ilya Fondaminsky ('Bunakov'), a veteran SR who later converted from Judaism to Orthodox Christianity and was murdered in the Auschwitz concentration camp in 1942.

He wrote his memoirs, Eto Bylo Davno (It was Long Ago), covering the pre-war period; they were published posthumously in 1933.
