Margaret Graham Moore of Greenwich, Conn., a passenger on the Titanic when the ship sank on her maiden voyage in April 1912, died in Greenwich Hospital yesterday. She was 83 years old.

The 882-foot luxury liner, crowded with celebrities, was en route from Southampton, England, to New York City, when she struck an iceberg off Newfoundland and sank within about three hours. The loss of life was reported as 1,517 persons.

Mrs. Moore, who was then 19 years old, “was nibbling at a chicken sandwich” with her governess, Elizabeth Shutes, when the accident occurred, according to the book, “A Night to Remember,” by Walter Lord. The women made their way to a lifeboat and were among those picked up by the Cunard liner Carpathia. Miss Graham’s mother, Mrs. William T. Graham, also was saved.

Mrs. Moore was the widow of Eugene Moore, a senior executive of the law firm of Manning, Maxwell & Moore, in Stratford, Conn.

Survivors include a daughter, Mrs. Margaret Clucas; 2 sons, Eugene M. and William G. Moore; 12 grandchildren and 4 great-grandchildren.
