Benjamin Franklin Edwards III (October 26, 1931 – April 20, 2009) was a stockbroker who expanded A. G. Edwards, a brokerage firm founded by his great-grandfather, from a regional firm to a nationwide stockbroking powerhouse, building it into the largest American brokerage firm headquartered outside of New York City. He built what was the world's largest collection of Imari porcelain, a 3,000-piece portion of which was sold at auction for $6 million.
