Office of Science and Technology, Executive Office of the President (now the White House Office of Science and Technology Policy). MacLeod was the first person to hold the position of deputy director of OST and remained there until 1966, serving as an advisor to President Lyndon B. Johnson after Kennedy's assassination. It has not been possible to find documents that confirm who conceived of a collaborative medical research enterprise between the United States and Japan. However, the idea is often attributed to MacLeod, who became chairman of the first U.S. delegation to the USJCMSP in 1965. MacLeod was an elected member of the American Academy of Arts and Sciences and the American Philosophical Society. He was named President of the Oklahoma Medical Research Foundation in 1970. He remained in that position until his death in 1972.
