A showboat, or show boat, was a floating theater that traveled along the waterways of the United States, especially along the Mississippi and Ohio rivers, to bring culture and entertainment to the inhabitants of river frontiers. Showboats were a special type of riverboat designed to carry passengers rather than cargo, and they had to be pushed by a small (and misleadingly labeled) towboat, also known as a pusher, which was attached to it. Showboats were rarely steam-powered because the steam engine had to be placed right in the auditorium for logistical reasons, therefore making it difficult to have a large theater. History During the American frontier era, populations of potential audiences were widely scattered about the area that is now the United States. Actors traveled to America from England, and theatre venues as well as touring companies were developed. Noah Ludlow, an early pioneer in travelling theater, purchased a keelboat in 1816 for $200 and named it Noah's Ark. Ludlow and 11 associates, together known as the American Theatrical Commonwealth Company, climbed aboard and traveled down the Ohio and Mississippi Rivers, stopping to perform whenever they could. It is not clear whether they ever performed on the boat, or just used the boat as a means of travel. If they did, in fact, perform on the boat (as is probable), then Ludlow's Noah's Ark would have been the first showboat. British-born actor William Chapman, Sr. created the first deliberately-planned showboat, named the Floating Theater in Pittsburgh in 1831. He and his family of nine, along with two other people, lived on this boat and performed plays with added music and dance at stops along the waterways. The price of admission was anywhere from a peck of fresh vegetables to 50 cents a person. After reaching New Orleans, they got rid of the boat and went back to Pittsburgh in a steamboat in order to tour down the river once again the following year. In 1836, the family was able to afford a new, fully equipped steam engine with a stage. In 1837, it was renamed Steamboat Theatre. Many other showboats followed the Floating Theater onto the rivers in the following years, and some of them began to do other performances besides theater. One popular showboat during this period was the Floating Circus Palace of Gilbert R. Spalding and Charles J. Rogers, built in 1851, that featured large-scale equestrian spectacles. By
