Joseph Patrick Kennedy (September 6, 1888 – November 18, 1969) was an American businessman, investor, philanthropist, and politician. Known for his own political prominence as well as that of his children, he was the patriarch of the Kennedy family.
Kennedy was born into a political family in East Boston, Massachusetts. After making a large fortune as a stock and commodity market investor, he invested in real estate and a wide range of privately controlled businesses across the United States. During World War I, he was an assistant general manager of a Boston area Bethlehem Steel shipyard; through that position, he became acquainted with Franklin D. Roosevelt, who was the Assistant Secretary of the Navy. In the 1920s, Kennedy made huge profits by reorganizing and refinancing several Hollywood studios; several acquisitions were ultimately merged into Radio-Keith-Orpheum (RKO) studios. Kennedy increased his fortune with distribution rights for Scotch whisky. He owned the largest privately owned building in the country, Chicago's Merchandise Mart.
Kennedy was a leading member of the Democratic Party and of the Irish Catholic community.
