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

He gave the two-foot-tall Charles a new 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 school teacher. 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 two thousand guests. Crowds filled the streets of New York to have a look at their tiny wedding carriage. The couple even met with President Abraham Lincoln 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.
