Once located at the northwest corner of Waterloo Avenue and Glasgow Street, the Guelph Elastic Hosiery Company is credited with the invention of the jock strap, says Heritage Guelph.
At the time it was in the original South Ward schoolhouse. Today the site is home to College Auto Tech.
The hosiery company was started in 1907 on Wilson Street by Joe Cartledge and quickly expanded operations and moved into the South Ward school building a few years later. The firm later moved to the Colonial Dress Building on Dublin Street, and then to a new facility on Speedvale Avenue.
The company is now known as Protexion Products.
