Barnum's American Museum was a dime museum located at the corner of Broadway, Park Row, and Ann Street in what is now the Financial District of Manhattan, New York City, from 1841 to 1865. The museum was owned by famous showman P. T. Barnum, who purchased Scudder's American Museum in 1841. The museum offered both strange and educational attractions and performances. Some were extremely reputable and historically or scientifically valuable, while others were less so.
