　　 Baseball was invented by Abner Doubleday in 1839 in Cooperstown， New York. But Doubleday had nothing to do with the game. American baseball has its nearest ancestry(祖先)in an English game called rounders， which， called town ball， was played in America in the 1800s. There are some differences

　　between rounders and American baseball. Printed rules for rounders have appeared since 1828.

　　 How， then， was Doubleday said to be the inventor？ In 1907， a special baseball commission(委员会)had been set up to find an American "inventor". They reached an agreement that Doubleday was its man， based only on a letter it had received from one Abner Graves. He said they had been schoolmates and he had been present at Cooperstown in 1839 when Doubleday designed baseball. But it's now known that no member of the commission ever met with Graves or had any communication with Graves.

　　 It should be noted that Graves was five years old in 1839，15 years younger than Doubleday， who entered West Point at the time. Further， Doubleday later enjoyed a great military career(军事生涯)there. He left a large collection of letters and diaries. But none of them mentioned baseball-nor did the notice of his death in the New York Times. In fact， the Baseball Hall of Fame calls Alexander J. Cartwright， who was a founder of the New York Knickerbockers， the Father of Modern Baseball. If he and his teammates didn't invent the game， at least they helped give it a structure(结构)that can be recognized today.

　　 But some untrue things die hard，and there's little doubt that the Doubleday story will remain a hit with future fans.
