Joseph N. Welch

Joseph Nye Welch (October 22, 1890 – October 6, 1960) was the chief counsel for the United States Army while it was under investigation for Communist activities by Senator Joseph McCarthys Senate Permanent Subcommittee on Investigations, an investigation known as the Army–McCarthy hearings. His confrontation with McCarthy during the hearings, in which he famously asked McCarthy At long last, have you left no sense of decency? is seen as a turning point in the history of McCarthyism.
