Avraham  was born in Warsaw  1898 to Rabbi Chaim Ya’acov Weintal and Tsipora, sixth of ten children. His father, a wealthy button maker was sole manufacturer for the Czar’s Army, took Avraham along on a business trip. On their way, WWI began,  and they couldn’t return. Drawn to Chovevay Zion,  the father desired to make Aliyah, therefore took his son to Israel via Egypt, to visit holy places, and find land for acquisition. Fifteen-year-old Avraham refused to return to Poland and was lodged with a Jerusalem family. He Hebraized his name to Gafni, and went to study Construction Engineering in Beirut. After graduating he returned, married Jenya Krasnitsky and they settled in Petach-Tikva, where daughter Tsipora was born. He worked as a teacher, surveyor, and as an engineer, although dreamed of farming. He joined a nucleus of Dutrch immigrants and in 1925 established a Moshava north of Petach-Tikva, Ramatayim. They built their home, established a poultry farm and planted an orchard. In the late 1920s, Chaim Ya’acov liquidated his businesses and made Aliyah with the rest of his family and property. Settling in Herzliya, they acquired lands and planted orchards. Avraham fiercely fought Left-wing/Histadrut pressure to take over the Ramatayim labour market and public services. He withstood harsh pressures and  recurring “bait” to join the Left, until  bitter confrontation erupted. To safeguard the settlers’ independence, he laboured hard to establish a school and healthcare clinic, separate from the LABOURWorkers Movement. During the 1936-1939 riots he objected to the Establishment’s non-retribution policy; when WWII broke out he enlisted in the British Army without preconditions. From there, his way to the underground was short. Yerachmiel Ahronson turned to him on behalf of Lehi, Avraham acquiesced immediately and became a major Lehi backer/supporter in Ramatayim. He hid ‘wanted’ Lehi members in his house, recruited supporters, and obtained a  training hut. A weapons stache-site was dug in his yard, and his equipment served members who were writing instruction manuals. His eldest, Tsipora, joined the underground soon afterwards, then second daughter Michal, and  son Giora, who although too young to join,  helped in various ways. In old-age, he loyally donated funding to the Scholarship Foundation and his books to Beit-Yair. Avraham had eleven grandchildren. He passed away on December 12,1987.
