Robert Plath, inventor of rolling luggage

Navigating an airport became considerably less difficult when Robert Plath, a pilot for Northwest, took a small suitcase, stood it up, and added wheels. Fellow crew members saw the bag and begged him to make luggage for them. TravelPro, the company he subsequently founded, earned a spot on the Inc. 500 in 1992. It also changed the economics of travel, as more passengers opted to fly with only carry-on luggage. Plath sold his business in 1999, and semi-retired. "I had no idea it would take off like it did," he told USA Today in 2003.
