Ernest Brook made his first motor in Huddersfield, UK in 1904 forming Brook Motors, whilst Colonel Crompton had formed R.E.B. Crompton & Co. in 1878. The two organisations came together in the 1970s to form the company that is now recognised the world over as Brook Crompton.

​

Growth through acquisition followed and Brook Crompton today incorporates many well know names from the history of UK electric motor production including Brook Motors, Crompton Parkinson, Electro drives (itself including AI and English Electric), Newman and Hawker Siddeley Electric Motors.
