Chubb locks

The mighty Chubb lock company was started in Portsmouth in 1818 when the first locking mechanism that could not be picked or forced, the detector lock, was invented and patented from a tiny house in Daniel Street. The inventor was a locksmith, Jeremiah Chubb, and the businessman who built the company up was his brother Charles. By 1840 Chubb was already a household name and although huge purpose built factories were subsequently built in London and Wolverhampton, the Chubb family kept their connections with Portsmouth for many years.
