Robert Emmett O'Connor (March 18, 1885 – September 4, 1962) was an American film actor. He appeared in 204 films between 1919 and 1950. He is probably best known as the warmhearted bootlegger Paddy Ryan in The Public Enemy (1931) and as Detective Sergeant Henderson pursuing the Marx Brothers in A Night at the Opera (1935). He also appeared as Jonesy, (the older Paramount gate guard) in Billy Wilder's 1950 film Sunset Boulevard.
He also made a cameo appearance at the very beginning and very end of the MGM cartoon short Who Killed Who? (1943).
Robert Emmet (4 March 1778 – 20 September 1803) was an Irish nationalist and Republican, orator and rebel leader. He led an abortive rebellion against British rule in 1803. He was captured by the British, tried and executed for high treason against the British king.
Robert Emmet came from a wealthy Anglo-Irish Protestant family who sympathised with Irish Catholics and their lack of fair representation in Parliament. The Emmet family also sympathised with the rebel colonists in the American Revolution. While Emmet's efforts to rebel against British rule failed, his actions and speech after his conviction inspired his compatriots.
Robert Emmet was born at 109 St. Stephen's Green, in Dublin on 4 March 1778. He was the youngest son of Dr Robert Emmet (1729–1802), a court physician, and his wife, Elizabeth Mason (1739–1803). The Emmets were financially comfortable, with a house at St Stephen's Green and a country residence near Milltown. One of his elder brothers was the nationalist Thomas Addis Emmet, a close friend of Theobald Wolfe Tone, who was a frequent visitor to the house when Robert was a child.
