Holbrook Mann MacNeille (May 11, 1907–September 30, 1973) was an American mathematician who worked for the United States Atomic Energy Commission before becoming the first Executive Director of the American Mathematical Society.

He was born in New York City and was raised in Summit, New Jersey. He graduated with highest honors from Swarthmore College in 1928, and was a Rhodes Scholar at Balliol College, Oxford, England 1928–1930 receiving a B.A. in 1930 and an M.A. in 1947. He received a Ph.D. in Mathematics from Harvard University in 1935, was a Sterling Fellow at Yale University in New Haven, Connecticut 1935–1936 and a Benjamin Peirce Instructor at Harvard between 1936–1938. During this period his work resulted in the Dedekind-MacNeille completion theorem (see Dedekind cut), a generalization of Richard Dedekind's construction of real numbers from the ordered set of rationals. In summers he was also a partner in the Dave Richardson Laboratories in Bailey Island (Maine), which produced dogfish prepared for dissection at school laboratories.

He taught mathematics at Kenyon College in Gambier, Ohio as an associate professor (1938–1941), full professor (1941–1947) and chairman of the department (1945–1947).

World War II

During several of the years at Kenyon College he was on leave as Scientific Liason Officer (1944–1945) and Head of Mission (1945–1946) London Mission of the Office of Scientific Research and Development, American Embassy in London, England. During (1946–1948) he was Scientific Director of the London Branch Office of the U.S. Office of Naval Research and then during (1948–1949) spent more than a year as chief of the fundamental research branch of the Atomic Energy Commission in Washington, D.C. In 1948 he received the President's Certificate of Merit from President Truman.

After World War II

In November 1949 he became executive director of the American Mathematical Society where he served until 1954. From 1954-1961 he was professor and chairman of the Department of Mathematics at Washington University in St. Louis, Missouri, and then from 1961 professor and chairman of the Department of Mathematics at Case Western Reserve University in Cleveland, Ohio until his death.

During this latter period he became interested in teaching, and directed several educational movies as part of the Calculus Film Project of the Educational Media Committee of the Mathematical Association of America.
