He had congestive heart failure, said his son Marc Funn.
Mr. Funn, an Alexandria native who taught in the District and several Northern Virginia school systems over a 38-year career, began working in classrooms during an era when racial segregation was being forcefully challenged.
While teaching a history class to Alexandria seventh graders in 1957 — three years after the U.S. Supreme Court outlawed public school segregation — Mr. Funn said he was shocked to see the school system using a dated and racially offensive text on Virginia history.
It depicted slaves as cheerful and docile. It was also the same book the Alexandria school system had used when he was a student. He complained to the principal but was ordered not to make waves.
