"Marvin H. Albert, the author of more than 100 westerns, mysteries, spy novels and works of history, died on March 24 in Menton, in the south of France. He was 73 and lived in Mont Segur-sur-Lauzon.

The cause was a heart attack, said his daughter, Jan.

Mr. Albert was born in Philadelphia and served as a radio officer in the Merchant Marine during World War II. After working as the director of a children's theater troupe in Philadelphia, he moved to New York in 1950 and began writing and editing for the magazines Quick and Look. He turned to writing full time after the success of his novel "The Law and Jake Wade" (1956).

In addition to popular westerns, mysteries and novelizations of Hollywood films, he wrote "The Long White Road," a biography of the Arctic explorer Ernest Shackleton, "Broadsides and Boarders," a history of great sea captains, and "The Divorce," about Henry VIII. He wrote novels under his own name and under the pseudonyms Albert Conroy, Al Conroy, Nick Quarry, Anthony Rome, Ian MacAlister and J. D. Christilian."
