Menachem Ratzon (5 August 1919 – 12 November 1987) was an Israeli politician who served as a member of the first Knesset for Mapam.
Born in Petah Tikva shortly after the end of World War I, Ratzon worked in orchards, industry and as a tour guide.[1] He joined the Socialist League, which later evolved into Hashomer Hatzair Workers Party and then Mapam. He served on the actions committee of the Histadrut trade union, and was also a member of Petah Tikva's Workers Council, and director of its planning department.[1]
He was placed twenty-first on the Mapam list for the 1949 elections,[2] but missed out on a seat as Mapam won 19 mandates. However, he entered the Knesset on 10 April 1951 as a replacement for Dov Bar-Nir,[3] who resigned his seat. For the July 1951 elections he was placed seventeenth on the party's list,[4] but lost his seat as Mapam was reduced to 15 seats. He was twenty-third on the Mapam list for the 1955 elections,[5] but again failed to win a seat.
He died in 1987 at the age of 68. A street in Petah Tikva is named after him.
