Menachem was born on April 1,1927 in Berlin  Germany to  Bilha and Anshel. His father escaped the Nazis 1935 and immigrated to Israel; in 1936 his mother escaped with  Menachem and Tova. The family resided in Tel-Aviv. Menachem studied at ‘Tel-Nordau’ School and graduated 1943. After studying agriculture with the “Youth Aliyah”, he returned to Tel-Aviv working as an intern in vehicle electronics, studying Theoretical Electronics at ‘Montifiori High-School’ night-school. He joined Lehi’s ranks 1945.

Menachem was active in the Youth Department, circulating info-material. During one of the night operations he took part in replacing Tel-Aviv English street-name signs, with Hebrew ones. He participated in  “Brit-Hachashmona’im” youth, recruiting youngsters for Lehi. Following the UN decision, and the increase of Arab hostilities, he worked  with members of his cell safeguarding Tel-Litvinsky and region. He joined the IDF’s 89th Battalion’s First Company, under  Dov Granek. He took part in the liberation of Lod and Ramla, all the Battalion’s Negev battles and  liberation of Beer-Sheba. He was injured in Rafiach from a direct mortar-shell hit upon his armoured track-vehicle, and remained hospitalized a long  time. After discharge from the army 1950 and his rehabilitation, he settled in Beer-Sheba, where he built his home. He was involved in distribution of schoolbooks and stationary, very active in immigrant absorption and assistance to needy families. He donated and fundraised for school-libraries.

Following the Six-Day War he was active in the Settlement Movement. Menachem worked many years commemorating Lehi soldiers in Beer-Sheba, naming streets after them. He worked relentlessly for the dedication of the memorial plaque at the old train station  commemorating the fallen soldiers of the 8th Brigade who took part in the conquest of Beer-Sheba, but he passed away prior to its unveiling. He was elected ‘Esteemed Citizen of Beer-Sheba’ but could not attend the ceremony. Menachem passed away following a long illness on January 20,1996. He left behind  wife Rachel, two sons – Arieh and Ilan, and two grandchildren. His love for his country and  people was expressed by Yitzhak Shamir  writing about Menachem posthumously: “Menachem was a loyal and dedicated Freedom Fighter”.
