Oliver Joseph St John Gogarty was an Irish poet, author, otolaryngologist, athlete, politician, and wellknown conversationalist, who served as the inspiration for Buck Mulligan in James Joyces novel Ulysses.
Gogarty was bornAugust 1878 in Rutland Square, Dublin, the eldest child of Henry Gogarty, a welltodo Dublin physician, and Margaret Gogarty , the daughter of a Galway mill owner. Three siblings were born later. Gogartys father, himself the son of a medical doctor, had been educated at Trinity College and owned two fashionable homes in Dublin, which set the Gogartys apart from other Irish Catholic families at that time and allowed them access to the same social circles as the Protestant Ascendancy.
