In 1968, Mr. Leslie joined John E. Allen Jr. to expand a theater group Allen had started two years earlier. They formed the New Freedom Theatre, more commonly known as just the Freedom Theatre.
Though Mr. Leslie wrote plays and directed a little, he focused more on the theater's administration and, at one time, served as general manager, said his daughter Gail Leslie, director of operations at New Freedom Theatre.
She said her father took great pride in New Freedom's training program, which he developed and oversaw for a period.
Mr. Leslie had worked for 20 years as a circulation manager for the Evening Bulletin, supervising drivers and newsstand sales. When he retired in the late 1970s, he devoted all of his time to the theater, Gail Leslie said.
"Through many tough times when others might have wavered, Bob fought indefatigably for the theater to pull through," said Derek Hargreaves, president of the New Freedom board.
Sandra N. Haughton, executive director of the theater, said Mr. Leslie "insisted that the arts be taken seriously."
