Joseph (Yosef) Sagol (1913–2000) was a Turkish-born Israeli industrialist and founder of Keter Group, a leading global manufacturer of plastic consumer products. Born in Istanbul, Turkey, to a Sephardic Jewish family, he immigrated to Mandatory Palestine in 1943 amid World War II. In 1948, Sagol and his three brothers—David, Zvi, and Meir—established Keter Plastics in Kibbutz Sde Eliyahu in Israel's Beit She'an Valley. Starting with simple plastic items like buckets, sieves, and dustpans using rudimentary machinery, the company expanded rapidly under his visionary leadership into a multinational enterprise producing household goods, outdoor furniture, storage solutions, garden products, and more, achieving significant growth through innovation and exports. Sagol served as CEO of Keter Plastics and Chairman of Keter Group until his death on October 22, 2000, at the age of 87. He was married to Miriam Sagol, with whom he had children including son Sami Sagol, who succeeded him as leader of the family business. The Keter Group, now employing over 10,000 people worldwide with factories in Israel, Europe, and the US, and partnerships such as with Home Depot, exemplifies Sagol's entrepreneurial success in building a global brand from post-independence kibbutz roots. Known for his contributions to Israeli industry and kibbutz life, Sagol was a self-made entrepreneur who built an industrial empire from modest beginnings. No major controversies, legal issues, or political involvements are documented in public records.
