The panel tells the story of Bernard Sadow, whose rolling suitcase challenged assumptions about how travelers should carry luggage. Inspired by a wheeled platform at an airport in 1970, Sadow attached wheels to luggage and began pitching the idea to retailers. Sadow filed his rolling-luggage patent on February 16, 1970 and received U.S. Patent No. 3,653,474 in 1972. His design used four rollers and a flexible strap, allowing travelers to pull heavy luggage rather than carry it through increasingly large terminals. Retail resistance was real. Sadow recalled buyers believing men would consider rolling luggage “wimpy” and arguing that porters already carried travelers' bags. Macy's eventually embraced the product and began selling it in October 1970 as “The Luggage That Glides.” Sadow wasn't literally the first person ever to put wheels on luggage; earlier patents and prototypes existed. His breakthrough was successfully commercializing the concept. In 1987, pilot Robert Plath later improved rolling luggage with the upright, telescoping-handle Rollaboard.
