Mosze Klaynboym (later Sneh) attended high school in Poland before studying natural sciences, mathematics and medicine at the University of Warsaw, gaining an MD in 1935. Whilst a student, he was a member of the Yardinia Zionist student organisation, becoming its chairman in 1926, and was also chairman of the Medical Jewish Students Union.
He became the editor of the Nowe Słowo newspaper in 1931, and the political editor of Haynt in 1933. In 1932 he was elected to the central committee of the Zionist Federation of Poland, and was a leader of the radical Zionists. In 1935 he also became a member of the Zionist Executive Committee.
Upon arriving in Mandatory Palestine, he joined the Haganah, and was head of its general staff in 1941–1946.
In 1944 he joined the Jewish National Council, and became a member of the Assembly of Representatives. Between 1945 and 1947 he sat on the board of the Jewish Agency, heading its immigration department. In 1946 he became head of the Agency's political department for Europe. Sneh's name was on the British Police's wanted list in Operation Agatha, but he avoided arrest by fleeing to Paris.
Sneh was a member of the General Zionists party. In 1947, he joined Mapam and was appointed deputy editor of the party's newspaper, Al HaMishmar, a position he held until 1953. In 1949 he was elected to the first Knesset. Re-elected in 1951, he was part of the group that split from the party in 1953, when false accusations against its envoy during the Prague Trials led to the party renouncing its support for the Soviet Union. Sneh initially formed the Left Faction, before joining Maki in 1954.
He returned to the Knesset on Maki's list in the 1955 elections, but narrowly missed winning seat in 1959. However, he entered the Knesset six weeks later as a replacement for Meir Vilner. Re-elected in 1961, Sneh remained in Maki when two of the party's MKs broke away to form Rakah in 1965. He lost his seat in the 1965 elections when Maki was reduced to one seat (most of its vote having gone to Rakah), but returned to the Knesset again in 1969, remaining the sole Maki MK until his death in March 1972.
