General Lafayette Mabry, retired superintendent of transportation for the Bureau of Engraving and Printing, died Tuesday of a heart attack at Georgetown University Hospital. He was 69.

A native of Dinwiddie, Va., Mr. Mabry studied two years at Virginia State College in Petersburg before moving to Pittsburgh, where he worked in a steel mill for five years.

In 1930, he moved to Washington. After working as a sexton for the East Washington Heights Baptist Church, he went to work for the Bureau of Engraving and Printing. He began as an armored car driver and worked his way up to superintendent of transportation.

While he worked at the bureau, Mr. Mabry also held down a second fulltime job as an engineer at the Annapolis Hotel here.

A man who liked to spend his spare time fishing along the coast from Delaware to Norfolk, Mr. Mabry retired from government service in 1971. Until his death, he worked as a volunteer for the "Meals on Wheels" program, which provided hot meals to elderly shut-ins. He also volunteered his time driving senior citizens to clinics and other facilities.

Mr. Mabry was a big man, said a son, Lafayette General, and people didn't make remarks about his name. "I guess my grandmother figured if she named her sons after great men, they'd be great, too," said Lafayette Mabry. "I think in my father's case, she was right."

Mr. Mabry is also survived by his wife, Gertrude, of Washington, and another son, William Richard, also of Washington; two sisters, Alma Wyatt, of Dinwiddie, and Elsie Mabry of New York City; three brothers, Ulysses Grant Mabry, of Washington, Norman, of Baltimore, and Henry, of Pittsburgh; five grandchildren, and one great-grandchild.
