magazine as "Cancer Man Ewing"; the accompanying article described his role as one of the most important cancer doctors of his era. He worked at the Memorial until his retirement, in 1939. Under his leadership, Memorial became a model for other cancer centers in the United States, combining patient care with clinical and laboratory research, and it was said of him that "the relationship of Ewing to the Memorial Hospital can best be expressed in the words of Emerson, 'Every institution is but the lengthening shadow of some man.' Dr. Ewing is the Memorial Hospital". Memorial Hospital and the Sloan Kettering Institute (1934–1980) In 1934, John D. Rockefeller Jr. donated land on York Avenue for a new location. Two years later, he granted Memorial Hospital $3,000,000 and the hospital began their move across town. Memorial Hospital officially reopened at the new location in 1939. In 1945, the chairman of General Motors, Alfred P. Sloan, donated $4,000,000 to create the Sloan-Kettering Institute for Cancer Research through his Sloan Foundation, and Charles F. Kettering, GM's vice president and director of research, personally agreed to oversee the organization of a cancer research program based on industrial techniques. The originally independent research institute was built adjacent to Memorial Hospital. In 1948 Cornelius P. Rhoads became the director of Memorial. Rhoads had run chemical weapons programs for the US army in World War II, and had been involved in the work that led to the discovery that nitrogen mustards could potentially be used as cancer drugs. He fostered a collaboration between Joseph H. Burchenal, a clinician at Memorial and Gertrude B. Elion and George H. Hitchings at Burroughs Wellcome, who had discovered 6 MP; the collaboration led to the development and eventual wide use of this cancer drug. From the mid-1950s to the mid-1960s Chester M. Southam conducted pioneering clinical research on virotherapy and cancer immunotherapy at MSK; however he conducted his research on people without their informed consent. He did this to patients under his care or others' care, and to prisoners. In 1963 some doctors objected to the lack of consent in his experiments and reported him to the Regents of the University of the State of New York which found him guilty of fraud, deceit, and unprofessional conduct, and in the end, he was placed on probation for a year. Southam's research experiments and the case at the Regents were followed in
