From an AP story by Jimmy Golen headlined “Bill Russell, NBA great and Celtics legend, dies at 88”:

Bill Russell, the NBA great who anchored a Boston Celtics dynasty that won 11 championships in 13 years — the last two as the first Black head coach in any major U.S. sport — and marched for civil rights with Martin Luther King Jr., died Sunday. He was 88.

His family posted the news on social media, saying Russell died with his wife, Jeannine, by his side.
