John Banvard was born in New York and was educated in high school. When his father went bankrupt, he began to travel around the United States, and supported himself with paintings he exhibited.
In 1840 he began to paint large panoramas of the whole Mississippi River valley. He traveled through the area in a boat, made preliminary drawings and supported himself with paintings and hunting. He combined the preliminary sketches and transferred them to a canvas in a building erected for this purpose in Louisville, Kentucky. His largest panorama began as 12 feet (3,6 m) high and 1300 feet (369 m) long and was eventually expanded to about half a mile (about 800 meters) although it was advertised as a "three-mile canvas". It toured around the nation, and was eventually cut up into hundreds of pieces, none of which still exist today.
In 1846 he began to travel with this panorama in Europe, Asia and Africa and even gave Queen Victoria a private viewing. His portrait was painted in 1849 by the English artist Anna Mary Howitt. During his travels he also painted panoramas in Palestine and the Nile River Valley.
Banvard had a rivalry with panorama performers John Rowson Smith and Richard Risley Carlisle. Banvard called them imitators and "unprincipled persons". They in turn referred to the "crude efforts of the uncultivated artist" Banvard. Banvard suggested that Smith and Carlisle's panorama was actually painted by George Catlin, who had copied the image after his own panorama.
On his return his invested part of the fortune he had made in 60 acres (240,000 m2) overlooking Cold Spring Harbor on the North Shore of Long Island, where in 1852-55, in competition with P. T. Barnum's palace "Iranistan" in Bridgeport, Connecticut, he proceeded to design and have built a baronial residence from its eastern shore, which, it was given out, was intended to resemble Windsor Castle; he named the place Glenada, the glen of his daughter Ada, but the locals called it "Banvard's Folly". After his death it became a fashionable resort hotel, The Glenada.
The Brooklyn-based history band Pinataland recorded a song about Banvard's travails for their 2008 album "Songs for the Forgotten Future Vol. 2".
In 2016, a new musical entitled Georama: An American Panorama Told on Three Miles of Canvas premiered at the Repertory Theatre of St. Louis . The musical tells Banvard's life story through his rise and fall as an artist, his conflict with PT Barnum and love for his wife Elizabeth. Georama was written by West Hyler, Matt Schatz, and Jack Herrick. It premiered in 2017 on August 2nd through 6th at New York Musical Theatre Festival, and starred PJ Griffith, Jillian Louis, Randy Blair, and Nick Sullivan.
