In 1859, The Great Blondin took the most dangerous tightrope walk of his career-a death-defying walk across Niagara Falls. History and STEAM combine for an edge-of-your-seat read. At the age of four, Jean-Francois Gravelet walked across his first balance beam. Later, he took to the tightrope like a spider to its web and climbed toward stardom. Though his feats became more and more marvelous, he grew bored. That is, until he visited Niagara Falls and imagined doing something that no one else had ever accomplished. To cross the raging river, the Great Blondin needed determination, an understanding of engineering, and a belief that what he could imagine, he could accomplish. And in 1859, with all of his preparation complete, Blondin stepped out onto the most dangerous tightrope walk he'd ever faced.
