Harry Houdini, A Magical Life - web page has excerpt from book that confirms some of the above information. "While in Rochester, New York, in 1907, Harry performed his first Manacled Bridge Jump. ("Manacled" is another word for "handcuffed".) The scene was the Weighlock Bridge. Thousands began gathering beforehand to see Harry, shackled in handcuffs and chains, jump into the water far below. Harry waited till the crowd was silent, then took a deep breath...and leaped off the bridge. ... The onlookers held their breath. Would Harry free himself or would he drown? Fifteen seconds after Harry hit the water, a bare arm thrust up above the surface, holding the open cuffs. He'd done it!"
