The Rev. Francis A. Marks, 71, a retired administrator and editor at the Catholic University of America, died at Surburban Hospital in Bethesda on Tuesday following a heart attack. He lived in Rockville.

Mr. Marks was born in Brooklyn and grew up in Rochester. In 1926, he entered St. Bernard's Seminary in Rochester and was ordained in 1932. He taught at the Aquinas Institute and at St. Andrew's and St. Bernard's seminaries in Rochester until the 1950s. He then became pastor of a church in Trumansburg, N.Y.

Mr. Marks joined the faculty of Catholic University here as an assistant professor of English in 1960. He also was assigned to the staff of the New Catholic Encyclopedia, which is published by the university.

In 1962, Mr. Marks was named an assistant to Bishop William J. MacDonald, then the rector of the university. In 1969, he became editor of the Catholic University of America Bulletin. A year later, he was named editor of the Office of Publications. In that position, which he held until his retirement in 1974, Mr. Marks was responsible for all of the university's publications.
