Early life and education

Crompton's education was interrupted by the outbreak of the

Crompton & Co.

. Crompton became convinced of the future of electric lighting, and at the same time saw several faults in the French-developed arc lamps then in use. He developed his own design which gave a much brighter and steadier light than existing types. His faith in his design was such that he bought out T.H.P. Dennis and in 1878 Crompton & Co. was formed to manufacture, sell and install Crompton's lamp. His reputation quickly spread, to the extent that when

Standardisation

After the war, Crompton became concerned by the large range of different standards and systems used by electrical engineering companies and scientists. Many companies had entered the market in the 1890s and all chose their own settings for

Other interests

As well as his professional and private interests in engineering and electricity, Crompton was a keen
