Robert Raymond Moser, 86, an aerospace engineer for General Electric, died Thursday, May 2, of pneumonia at the nursing skilled facility at Shannondell in Audubon.

Mr. Moser's first job was as a design engineer for Baldwin-Lima-Hamilton Corp. in the mid-1950s.

A longtime friend referred Mr. Moser to General Electric, where he worked from July 1956 until retiring in 1990. Sometimes his office was in Philadelphia; at other times, in King of Prussia.

His family said that engineering was a passion for Mr. Moser and that he was "loyal and passionate about the company that employed him" for so many years.

Born in Philadelphia to William Weiser Moser and the former Lucille Salem, Mr. Moser was a longtime member of the Boy Scouts and spent many summers as a counselor for the Pennsylvania Society for Crippled Children and Adults in White Haven, Pa.

He graduated in 1945 from Germantown High School, where he ran track. He attended his 50th reunion in 1995.

Mr. Moser enlisted in the U.S. Army in World War II and was honorably discharged as a corporal in 1946.

He graduated from Pennsylvania State University in June 1950 with a bachelor's degree in mechanical engineering. During his college years, he closely followed the Nittany Lions.

At GE, he held many engineering and managerial positions, including project quality and test engineer for the military space program.

He participated in the Mercury Program and other projects during the late 1950s.

Mr. Moser traveled widely and was a passionate amateur photographer. During one trip to British Columbia, he met Beatrice Elaine Westlund from Minneapolis.

He flew back and forth between Philadelphia and Minneapolis for one year, courting her, before they married in 1963. The two lived in Wayne for 46 years.

He loved family gatherings and watching the Phillies.

Surviving, in addition to his wife, are a son, David W.; a daughter, Judith Moser Gunther; three grandchildren; and many nieces and nephews.

Services were Monday, May 6.
