American elevator safety mechanism inventor Elisha Otis was born on August 3, 1811, in Halifax, Vermont. Otis did not actually invent the elevator itself; instead, he invented something far more crucial: the automatic safety brake that prevented the platform from skyrocketing or plummeting if the main lifting cables snapped. To prove to a skeptical public that his invention was completely reliable, Otis staged a thrilling, high-stakes demonstration at New York City’s 1854 World’s Fair—held in the Crystal Palace. Standing high in the air on an open elevator platform, he deliberately ordered an assistant to cut the main support rope with an axe.
The platform dropped just a few inches before his automatic safety teeth locked into the guide rails, prompting a smiling Otis to famously reassure the gasping crowd, “All safe, gentlemen, all safe!” (the exact wording is traditional, though not contemporaneously verified). Three years later, in 1857, he installed the first successful passenger safety elevator in the E.V. Haughwout Building at 488 Broadway, helping launch the era of tall, elevator-served buildings.
