Joel Jacobson, AAI co-founder, dies


Joel M. Jacobson, a retired vice president of the Martin Marietta Corp. and one of the founders of the AAI Corp., died Sunday at Johns Hopkins Hospital of complications after surgery.

Mr. Jacobson, who was 83 and lived in Pikesville, retired in 1976 as vice president for development of Martin Marietta's Aerospace Group, a post he had held since 1968, when he left AAI.

After helping to start what was then known as Aircraft Armaments Inc. in 1950, he was the company's president and then chairman of the board before returning to Martin Marietta.

He had been chief structural test engineer and director of technical engineering when he first worked at what was then the Glenn L. Martin Co.

Also, he had worked for what is now Fairchild Industries and for the General Aviation Corp. He wrote many papers on aircraft structure and design. Mr. Jacobson held several patents on aircraft and electrical equipment.

Born in Leeds, England, but reared in Chicago, he earned bachelor's and master's degrees from what is now the Illinois Institute of Technology. In the 1930s he was a reserve officer in the Army Corps of Engineers.

He is survived by his wife of 62 years, the former Sally Cooper; a daughter, Susan J. Bautz of Pikesville; and three grandchildren.

Private services are planned, but the family suggested memorial contributions to The Montessori School on Falls Road in Brooklandville.
