The team toured the world, including a series of games in Moscow in 1959 during the height of the Cold War.
"A Soviet audience of 14,000 sat almost silently, as if in awe, through the first half of the game," according to a United Press International report. "It warmed up slightly in the second half when it realized the Trotters are more show than competition."
During one outdoor game in Europe, they played in the rain while holding umbrellas, Mitchell said. "They were that good," he said.
After his basketball career, Mr. Washington joined Pepsi-Cola, working in advertising, then sales, and rising to the position of community relations manager.
Mr. Washington is featured in a mural, sponsored by Pepsi-Cola, on Chelten Avenue near Wayne Avenue.
He was born and raised in Germantown and graduated from Germantown High School.
Before joining the Navy, he played one season for the New York Renaissance. Several other players on the "Rens" came from Philadelphia and had played with Mr. Washington at the Christian Street YMCA, the hot spot for the city's best youth players.
Mr. Washington played basketball while in the Navy and his skills caught the eye of Abe Saperstein, who ran the Globetrotters - and who, Mr. Washington later complained, kept most of the money. Mr. Washington played briefly with the Washington Bears before joining the Globetrotters.
"I had a good career with the Globetrotters," Mr. Washington told the Philadelphia Tribune last year. "I enjoyed it. If it had not been for the Globetrotters, there would not have been an NBA as we know it."
He is survived by his wife, Barbara Merriweather; son Frank Jr.; sister Eunice Green; and three grandchildren.
Funeral services will be at 11 a.m. Thursday, Jan. 31, at Salem Baptist Church, 610 Summit Ave., Jenkintown.
