An obituary in Tuesday's editions of The Washington Post about retired Rear Adm. Richard Robert McNulty, 81, who died Saturday in Gloucester, Mass., stated incorrectly that he was superintendent of the U.S. Merchant Marine Academy at Kings Point, N.Y., from 1946 to 1953. Adm. McNulty held that post from 1946 to 1948.

Retired Navy Rear Adm. Richard Robert McNulty, 81, a former superintendent of the U.S. Merchant Marine Academy who later taught at Georgetown University, died Saturday in a retirement home in Gloucester, Mass. He had arterioschlerosis.

He also worked for a New York shipping line before being called to active duty in the Navy during World War II.

In the war, he earned the legion of Merit as supervisor of the U.S. Merchant Marine Cadet Corps. He was superintendent of the U.S. Merchant Marine Academy at Kings Point, N.Y., from 1946 to 1953.

He then joined the staff of Georgetown University as director of the international transportation program in the Foreign Service School. He held this post for nine years before retiring.

He lived in Bethesda before returning to New England in 1973.His wife, the former Sue Alice Collins, died in 1969. Adm. McNaulty's suvivors include a brother and two sisters, all of Gloucester.
