J.R. Clancy traces its identity to Syracuse stagehand John Clancy, whose 1882 pulley inventions solved an unusually difficult scenery change and launched a company founded in 1885. Known for treating theatre safety as central to its work, the company created the fire line and self-closing fire curtain after the 1903 Iroquois Theatre fire; its rigging systems now serve performance venues ranging from grand opera houses to local high schools worldwide.
