A student was going to spend his holiday in a cool mountain village. That evening he stayed at an inn (小旅馆) near the railway station (火车站). Before going to bed, he went to the boss of the inn and said, "Excuse me, sir. Will you please wake me up at a quarter to five tomorrow morning? I'll take the five o'clock train."

    "Oh, sorry, sir," the boss said in a hurry, "I'm afraid I can't. I won't be able to get up so early." The student was disappointed. When he began to return to his room, be stopped and asked, "Have you got an alarm-clock (闹钟)? Maybe it can help me."

    "Wait a minute, then." The boss said and brought out an alarm-clock. "Here you are, sir." "Thank you very much." The student said happily. But he found it was rusty (锈的) when he had a look at it. And it sometimes worked and sometimes didn't. He asked, "Will it ring in time?" "I don't know, either." said the boss, "But it doesn't matter. You just give it a good shake at a quarter to five. And it will ring on time."

In 1826, a Frenchman named Nieple needed pictures for his business. But he was not a good artist. So he invented a very simple camera. He put it in a window of his house and took a picture of his garden. That was the first photo.

The next important date in the history of photography was in 1837. That year, Daguerre, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing. The kind of photo was called a Daguerreotype. Soon, other people began to use Daguerre's way. Travelers brought back wonderful photos from all over the world. People took pictures of famous buildings, cities and mountains.

In about 1840, photography was developed. Then photographers could take pictures of people and moving things. That was not simple. The photographers had to carry a lot of films and other machines. But this did not stop them, for example, some in the United States worked so hard.

Mathew Brady was a famous American photographer. He took many pictures of great people. The pictures were unusual because they were life like. 

Photography also became one kind of art by the end of the 19th century. Some photos were not just copies of the real world. They showed the author's ideas and feelings, like other kinds of art.
