His exact year of birth is also unknown, but the Guinness estate estimated it to be September 28, 1725. It is also rumored that Guinness’s father was partial to brewing beer and did so for the other workers on Price’s estate. In 1752, Guinness received the inheritance money, establishing a lease on his first brewery in Leixlip three years later. We can never know if Arthur Guinness was confident enough in his brewing skills to predict his own incredible success but nonetheless, he signed a 9,000-year lease on the brewery for £45 a year. Living on through the Arthur Guinness Fund today, Arthur is rumored to have been an all-around good guy, often donating to charities, working to ensure better healthcare for the poor, and even publically supporting Catholic emancipation in 1793, despite coming from an upper-class Protestant family.
