Sir Arthur Guinness, founder of the Guinness Company, is reportedly born in Co. Kildare on this day in 1725. There is much historical debate over whether this is the actual birthdate of Sir Arthur, yet to end further debate, the 1991 Guinness Company chose September 28 as his official birth date. After inheriting money from his godfather, 27 year old Arthur established a brewing company at Leixlip, just outside of Dublin. In 1759, Guinness established another factory in Dublin at St. James’s Gate. Arthur’s Day, as September 28th is known, is a day for celebration and drinking Guinness.
