Robert Battey Greenough (November 9, 1871 - February 16, 1937) was a leading American cancer specialist in the early 20th century.
He was an Assistant Professor of Surgery at Harvard Medical School from 1909 until 1932, and was a surgeon at Massachusetts General Hospital for most of his career.
He surveyed surgeons in an attempt to develop best practices for cancer diagnosis and treatment, publishing guidelines on it in 1917.
Greenough's 1937 Associated Press obituary described this address as a "turning point" because bodies such as this one had previously been opposed to such plans.
[5] Greenough died of a heart attack on February 16, 1937, at age 65, survived by his wife and four daughters.
