The wheeled suitcase seems so obvious now that its absence for millennia feels absurd. We had wheels. We had luggage. Yet for 5,000 years, no one thought to combine them. The delay wasn't technological-it was cultural. Carrying heavy bags was a test of masculinity, a badge of strength. When Bernard Sadow finally patented wheeled luggage in 1972, department stores laughed him out of their offices. "No man would ever use a suitcase with wheels," one executive declared. The resistance wasn't about function; it was about gender. Real men didn't need help carrying their burdens. This story isn't just about suitcases. It's about how deeply gender shapes what we invent, who gets credit, and which problems we deem worth solving. From spacesuits sewn by seamstresses to computers programmed by women, history is full of innovations delayed or erased because they didn't fit masculine ideals. Understanding this pattern reveals how much potential we've wasted-and how much we still overlook today.
