The word, “photography”, was first used in 1839. It comes from the Greek words that mean “to write with light”. But photography could only give people static pictures. So scientists were trying hard to find ways to make pictures that can move. They made lots of experiments, but failed again and again. It was Eadweard Muybridge who finally succeeded. He was the first photographer to try this successfully. But how did he make it? It was an interesting story.

Back in 1872, people didn’t know exactly whether all four of a horse’s hooves (蹄) left the ground at the same time when it was running. A gentleman called Leland Stanford made a bet with his friend about it. Most people believed that a horse always had one hoof on the ground, or it would fall over. But Stanford didn’t think so.

At that time, it was hard to know who could win the bet, because a horse’s legs move so fast that it is impossible to tell just by looking. So they needed a way to record the movement of a running horse. Then Stanford offered $25,000 to the famous photographer, Muybridge, to help find the answer. In the beginning, Muybridge failed to get clear images, but he didn’t give up. He continued to improve his cameras. In 1878, after many experiments, he managed to get a sequence (连续) of 12 photos. One of them clearly showed that all four of the horse’s hooves were off the ground at the same time. And when the photos moved fast, people could see a horse running.

Though is usually considered as the person who created the first movie in 1889, it was the work of Eadweard Muybridge and the bet that led to Edison’s invention.
