Abraham is an entrepreneur in the pharmaceutical and diet food businesses. Shortly after returning from a tour in Europe as a member of U.S. Army in 1947, he purchased Thompson Medical Company, which had annual sales of $5,000. It is now a privately held company distributing a variety of products. His interest in the weight loss industry led him to develop the now-independent SlimFast Foods. Abraham is dedicated to many causes, including improving health care and nutrition, encouraging Middle East peace, and broadening educational opportunities. His gift to the Mayo Clinic created the Dan Abraham Healthy Living Center; he also endowed the S. Daniel Abraham Chair in Middle East Policy Studies at Princeton University and a chair in nutritional medicine at Harvard University Medical School. Additionally, he has funded the Dan Abraham School for Business Administration and Economics at Bar-Ilan University in Israel, the S. Daniel Abraham Israel Program at Yeshiva University, and the S. Daniel Abraham Honors Program at Yeshiva University’s Stern College for Women. Abraham and his wife Ewa reside in Palm Beach with their two children. He also has four grown daughters, 27 grandchildren, and four great-grandchildren. He holds honorary doctorates from Ben-Gurion University, Bar-Ilan University, and Yeshiva University.
