Kremer promoted products owned by General Mills, including Lionel Trains, and was an early pioneer in recognizing the potential of an unknown hobby kit made by Craftmaster, called "Paint by Number."
Born in Philadelphia, Kremer graduated from Simon Gratz High School and earned a bachelor's degree from Temple University. He attended Temple Law School for one year.
At one time, he was ranked No. 1 on Temple's Table Tennis Team. He soon became a nationally ranked table-tennis player -- achieving the rank of 17th in the country. In later years, he became an avid tennis player and was a member of the Logan Tennis Club for more than 50 years.
A veteran, he served in the Army Air Corps as a cryptographer and meteorologist during World War II from 1941 until 1945, stationed in Alaska and the Aleutian Islands. During his military service, he survived an airplane crash in Alaska.
Kremer worked for the Department of Public Assistance in Philadelphia after the war. He took extensive courses at Penn State University to learn as many languages as possible.
Kremer is survived by his wife of 43 years, the former Gloria Lorch; daughter Randi Kremer Saunders; sons Richard Haaz and Robert Haaz; sister Edith Steele; and five grandchildren.
