Louis J. Incognito, 72, of Mt. Airy, a retired computer programmer and community activist, died of renal cell cancer Jan. 25 at the Hospital of the University of Pennsylvania.

Because of his illness, Mr. Incognito was forced to retire in 1998 from Professional Partners Group, where he had been a consultant to the General Accident Insurance Co. Prior to 2000, he had been involved in rewriting and installing the company’s Y2K program. Other programs that he had written earlier are still in use today.

He began his career as a programmer with the General Electric Co., and had worked for Merck, Sharp & Dohme, and for Union Fidelity and Reliance insurance companies.

He had been active in his community for many years and had served as vice president of East Mt. Airy Neighbors. He was a regular volunteer at Mt. Airy Day until he became too ill to continue.

He was a member of several peace organizations for more than 40 years and participated in numerous marches and demonstrations. He wrote frequently on political and social issues for local newspapers and was an advocate for public education.

Born and raised in Philadelphia, he was a graduate of LaSalle College High School and what is now LaSalle University, where he was a mathematics major.

Mr. Incognito is survived by his wife, the former Sheila Kilian; sons Louis, Paul, David and Andrew; a daughter, Jodi Haasz; his mother, Angela; a brother, James, and nine grandchildren.

A memorial service will be held at 2 p.m. Saturday, Feb. 25, at the Unitarian Society of Germantown, 6511 Lincoln Drive, in Mt. Airy. Memorial donations may be made to East Mt. Airy Neighbors, 7301 Germantown Ave., Philadelphia, PA 19119. – WF
