Pasch was 91 years old.
Pasch started his career in advertising in firms such as Kenyon & Eckhardt and Ogilvy & Mather on Madison Avenue in New York City, working for well-known companies' advertising campaigns like Clearasil, Scotts Lawn and the United Nations.
He left the business in the 1970s while retiring to Babylon Village. He later became the commodore of the Babylon Yacht Club, where he had taken a family sloop to the seas often.
His advertising work helped in efforts to save the Conklin House, home of one of the village's earliest known settlers – Nathaniel Conklin. The home had fallen into disrepair during the 1980's before Pasch and other residents pursuaded the village to purhcase and restore the home in 1990.
Pasch was also a founding member of the Babylon Youth Project in January 1981, a group that works with children during afterschool hours from simple entertainment to further learning.
Pasch, a Brooklyn native, is survived by his wife, Fran, and three children and numerous grandchildren and great-grandchildren.
