The company was founded by Harold Humphreys, along with his brother Wallace in a small workshop in Wilmslow, Cheshire, inspired by the growing interest in football witnessed nationwide. The name "Umbro" is a quasi-portmanteau inspired by Humphreys Brothers Clothing. Umbro's kit debut was in the 1934 FA Cup final, when both teams Manchester City and Portsmouth wore kits designed and manufactured by the company. Other teams supplied by Umbro during the 1930s and 1940s were Sheffield United, Preston North End, Manchester United and Blackpool.
