The Rev. Laurence McHugh, SJ, 69, a retired professor of philosophy and theology at Georgetown University, died Wednesday at Georgetown University Hospital. He had cancer.

Father McHugh was born in Worchester, Mass. He grew up in Washington and graduated from Gonzaga High School. He entered the society of Jesus at the seminary at St. Andrews-on-Hudson in Poughkeepsie, N.Y., in 1927. He studied there until 1931, when he transferred to the old Woodstock Theological College at Woodstock, Md., to continue his education. He was ordained at Woodstock in 1940 and returned to Washington two later.

He joined the Georgetown faculty in 1942 as an assistant professor of physics. He also taught at Gonzaga High School during that period.

When World War II ended in 1945, Father McHuch became the veterans counselor at Georgetown in addition to his teaching duties. From 1948 to 1958, he was a professor of philosophy, and in 1953 and 1954 was a regent of the Georgetown School of Nursing.

From 1958 to 1962, he was an associate editor of America magazine, a Jesuit publication, in addition to his teaching duties. He was a professor of theology from 1967 until his retirement in 1974.

Father McHugh was well known as a preacher and as a leader of retreats during his years at Georgetown. He lived at the Jesuit Community at the university.

Survivors include his mother, Mrs. Charles McHugh, of Washington, and two sisters, Mary Corridon, of Bethesda, and Emily Carr, of Memphis, Tenn. CAPTION: Picture, THE REV. LAURENCE McHUGH
