Ancient to 20th century
In the 19th century, variety and music hall theatres became more popular, and jugglers were in demand to fill time between music acts, performing in front of the curtain while sets were changed. Performers started specializing in juggling, separating it from other kinds of performance such as sword swallowing and magic. The Gentleman Juggler style was established by German jugglers such as Salerno and Kara. Rubber processing developed, and jugglers started using rubber balls. Previously, juggling balls were made from balls of twine, stuffed leather bags, wooden spheres, or various metals. Solid or inflatable rubber balls meant that bounce juggling was possible. Inflated rubber balls made ball spinning easier and more readily accessible. Soon in North America, vaudeville theatres employed jugglers, often hiring European performers.
