The first famous dance marathon in the United States was held in December 1909 in Butte, Montana. It was attended by more than 170 pairs. Dance marathon was stopped by a local sheriff after 15 hours marathon. He said that this dance is dangerous for their health. Same mass insanity began in 1923, when one 32-year old American danced 27 hours without a break, changed six partners and beat the previous British record. This achievement attracted the attention of the public and inspired others, especially women.
