When Charles Stratton was five, he stopped growing. His mother took him to see the famous showman, P. T. Barnum. Mr. Barnum thought a small person would be the perfect addition to his show. He hired Charles’ parents along with him, and they traveled the world together.

He gave the two-foot-tall Charles a name, General Tom Thumb. He taught Tom how to sing, dance, act and tell jokes. When he felt Tom was ready to perform on stage, he made up ads. To stir up great interest, he said that Tom was eleven years old and had come from England.

During the show, Tom fought battles pretendedly with tall people. He also danced upon a wooden plate held by a person who was eight feet tall. Tom’s act was very popular and brought in a lot of money. By the time Tom was an adult, he had grown very rich. He had become a billionaire at the age of twenty five.

Fortunately for Tom, Mr. Barnum added more little people to his show, and Tom became lucky in love as well. One of the little people was Lavinia Warren, a schoolteacher. Tom was able to win her love, and they married.

The ceremony and reception were the talk of the town. They were attended by many rich and famous people and by about 2000 guests. Crowds filled the streets of New York to have a look at their tiny wedding marriage. The couple even met with President on their honeymoon just before going to live in Tom’s house in Connecticut.

Their wedding, which took place during the Civil War, provided a welcome escape from the sad problems of war. Not willing to let this bit of sunshine fade, communities throughout the country sponsored (发起) “Tom Thumb” weddings. In these weddings, small boys and girls, all dressed up, went through marriage ceremony for fun.
