In the 1900s, Steel Pier in Atlantic City, New Jersey opened its first diving horse exhibition after its inventor, William "Doc" Carver's, horse fell into water after the bridge they were crossing collapsed in North Platte, Nebraska. Following the idea, Carver, in partnership with Al Floyd Carver, began touring the country, stopping by Hanlan's Point Amusement Park in Toronto, Canada in 1907, with his rider Lorena Carver who would dive with horses from towers of up to 60 feet. Later on, in 1924, Sonora Webster joined the show with her horse Red Lips. The High Diving Horses became the highlight of the Water Circus at Steel Pier with horses diving three to four times a day. One would assume that horses were injured multiple times but surprisingly, this was not the case. The only injury while the show ran was the blinding of Sonora Webster in 1931 after her and her horse lost their balance on the platform before diving. She continued diving with horses blind and in 1991, the film Wild Hearts Can't Be Broken was released based on her life. The shows received strong criticisms of animal welfare abuses with a decline in popularity after World War II with allegations of the use of prods, electrical jolts and trap doors to get unwilling horses to dive. Finally, in the 1970s, horse diving shows ceased to exist though a couple of years ago, an attempt to revive them was made at Steel Pier. It was quickly halted with the president of the Human Society of the United States saying "This is a merciful end to a colossally stupid idea.".
