Gogarty, Oliver St. John (gōˈgərtē) [key], 1878–1957, Irish author. A physician, he also served (1922–36) in the parliament of the Irish Free State. Gogarty is perhaps best known as the model for Buck Mulligan in James Joyce's Ulysses. As I Was Going down Sackville Street (1937) and It Isn't This Time of Year at All! (1954) contain reminiscences of Joyce, Yeats, and others in the Irish literary renaissance.
See his collected poems (1954); his essays, A Week End in the Middle of the Week (1958); biography by U. O'Connor (1963).
