Founded in 1922, and based in Des Peres, Mo., Edward Jones is a financial services company that focuses its business primarily on individual investors and small businesses. The company is a full-service investment broker, which means that it provides investment management services, much more so than brokerage services for self-directed accounts.
Edward was born in June 1239, the son of King Henry III. Weak and indecisive, Henry was not a bad manâjust a bad king. He was devoted to his family and took great pleasure in art and architecture. One of his pet projects was the rebuilding of Westminster Abbey in the Gothic style that was just coming into vogue.
