Robert Bentley

His works include the Manual of Botany and Medicinal Plants. He suffered from spinal arthritis (though this didn't stop him from performing several dance numbers with Astaire in Band Wagon), and died in London only four years later. Robert Bentley (1821-1893) was an English botanist. He made his film debut in the silent cinema, in 1917, but his best-known film is undoubtedly his venture into Hollywood, The Band Wagon (1953), in which he plays camp theatre director, Jeffrey Cordova, opposite Fred Astaire and Cyd Charisse. Buchanan made his first appearance on the UK stage in 1912, and on Broadway in 1924. Buchanan was born in Helensburgh, Scotland.

Jack Buchanan (April 2, 1891 - October 20, 1957) was a British actor and singer.
