Thus, four years after the founding of Kfar Yehezkel, the second workers' settlement in the Land of Israel, the Ptolemy (formerly Smilansky) family, who immigrated from Ukraine in 1925, joined its ranks: the parents Moshe and Leah, teachers of Hebrew, their daughter Tahia, about ten years old, and their toddler son, Yigal, less than one year old. On the ship that arrived from Odessa to Jaffa there were two more families of teachers, but they stayed in Tel Aviv, which seemed quite pioneering to them. Yigal grew up in Moshav at the foot of the Gilboa, in the heart of the Jezreel Valley, and studied until the XNUMXth grade at the school in the village that his father ran (one of his students, Azaria Alon, wrote highly of Moshe Ptolemy). The XNUMXth grade was in the Geva group, and Vigal and four other boys walked to the Geva every morning. When it rained and water flowed in the wadi between the settlements, crossing was not possible. Prof. Yigal Ptolemy. Contributed a lot to shaping the image of the Weizmann Institute
