at the Pneumoconiosis Research Unit in Penarth, Wales. He became involved in Zionist activities as chairman of the Friends of the Jerusalem University in Cardiff and chairman of the Zionist organization in Queensbury, London. Hadassah Director General Mann returned to Jerusalem with his wife and two children in 1949 to accept a medical post at Hadassah Hospital. That year, however, the campus on Mount Scopus was cut off from the rest of Jerusalem by the 1949 Armistice Agreements, and hospital departments and clinics had taken up residence in a series of derelict buildings in western Jerusalem. Mann was instead offered an administrative position as deputy to the director general of Hadassah, Eli Davis, which he accepted. The hospital sent him to Rochester, New York to receive training in hospital administration from Dr. E. M. Bluestone, former medical director of Hadassah. In early 1951, when Davis announced his resignation to return to general practice, Mann was named his successor. Mann proved to be a visionary director and successful fund-raiser, turning Hadassah from an institution crippled by war to one of the world's leading centers of medicine, teaching, and research. One of his first efforts was to locate a new campus for the hospital and raise the millions of dollars necessary to build it. The 600-bed hospital at Ein Kerem opened in May 1961. Mann also opened four out of the eventual five professional schools on that campus: pharmacology, dentistry, occupational therapy, and public health. On June 6, 1967, a day after Israel gained Mount Scopus in the Six-Day War, Jerusalem Mayor Teddy Kollek called Mann and told him, "If you want your hospital, come and get it". Over the next eight years, Mann supervised the renovation of the Mount Scopus campus into a 300-bed medical center. He also developed a "community based outreach health centre" at Kiryat Yovel. Over his three decades of leadership, Mann managed a budget that increased from $2.3 million to $93 million. He collected most of the funds for his projects from Hadassah, the Women’s Zionist Organization of America. Yad Sarah Mann retired from Hadassah on September 1, 1981, making him the longest-serving director general of the HMO; he served under ten presidents. He immediately undertook a full-time position as chairman of the Yad Sarah medical equipment lending organization, with which he had been involved on a volunteer basis since 1977. Mann's advice and expertise helped grow
