Alexander Marble (February 2, 1902 – September 13, 1992)[1] was an American diabetologist who spent the majority of his career at the Joslin Diabetes Center.
[2] He was awarded a traveling fellowship in the early 1930s to study in Austria, Germany and England, including at the laboratory of Henry Hallett Dale.
His research subjects at this time included pentosuria, glycosuria, xylose metabolism, and vitamin D.[1] Upon his return to the United States in 1932,[3] he was recruited by Elliott P. Joslin to join his diabetes clinic in Boston, where Marble was given his own laboratory and was appointed Director of Research.
[2] During the Second World War, Marble served in the United States Army Medical Corps, first at Cape Cod and later as Chief of Medicine at Harmon General Hospital.
After the conclusion of the war, he remained a consultant to the Army Reserve for another three decades, eventually being promoted to the rank of Brigadier General.
