Meir-Haim was born on March 30, 1930 in Tel Aviv, to Sonia and Israel. He studied in Neve Shaanan Elementary School. At age sixteen, he began working as an electrician in order to support the family, as his father had fallen ill. After two years of work, he attended the Max Pine School to complete his studies, but he had to drop out relatively soon, because in the meantime a number of important developments occurred in the Land of Israel: the underground was fighting the British, the Partition Plan had been announced and riots had erupted in the Arab community. Meir-Haim could not sit on his hands, so he joined Lehi to fight the enemy on two fronts: the British, to expel them from the Land of Israel; and the Arabs, to quell the attacks on the Yishuv. When the IDF was established after the establishment of the State, he went to enlist along with his fellow Lehi members, although his mother tried to dissuade him, as he was not yet of draft age.
Meir-Haim fought in the 8th Brigade, Battalion 82, in all of its battles: in the center of the country, Ramleh, Beit Naballah, Beersheba, Iraq Suwaydan, Auja el-Hafir, all the way to the alleys of el-Arish. He always volunteered for the most dangerous and difficult missions, and he was fearless.
After the War of Independence, the fighters were given the opportunity to join agricultural settlements at strategic points in the Negev, and Meir-Haim was inspired. A number of Lehi members joined the program, Meir-Haim among them. They established Kibbutz Neve Yair. Meir loved nature and animals, raising pigeons and shepherding. His colleagues describe him as a very sociable young man, friendly and eager to help, ready for every task. He assisted in construction and hooking up the electricity throughout the settlement.
However, even the kibbutz, a locale expected to be quiet and pastoral, was far from tranquil. The southern border was constantly infiltrated by malefactors coming from Egypt, bent on terrorism, murder and destruction. They would steal, shoot civilians and lay mines on the roads. The farmers experienced great stress, staying up at night to perform guard duty and patrol the area. Of course, Meir also went out on patrol, often under very dangerous conditions. On one of these occasions, on August 23.8.1949, he was killed by one of these infiltrators.,
Meir was buried in the Nahalat Yitzhak Cemetery of Tel Aviv.
