About Isaac Charles Johnson
- Isaac Charles Johnson (28 January 1811 – 29 November 1911) was a British cement manufacturer, and a pioneer of the Portland cement industry. Born in London, his father was a charge-hand at Francis & White's "Roman Cement" plant in Nine Elms.
- He himself worked there as a labourer from age 16 while studying chemistry.
- In 1833 he became manager of John Bazeley White's cement plant at Swanscombe on the Thames Estuary which at that time was producing "Artificial Cement" and "Roman Cement".
- Joseph Aspdin's product was successful but very expensive,and was later improved independently by his son William.
- Johnson set to work trying to discover its composition but because Aspdin's product was protected by explicit patents and extreme secrecy it was impossible to market a copy.
- After nearly two years' work, he succeeded and started marketing his own considerably improved version.
- Johnson, a highly moral man, Mayor of Gateshead and a JP, was able to claim that he was the inventor of "true" Portland cement and is generally recognised as such.
- Aspdin, however, was driven out of business by financial problems caused by the success of Johnson's superior and cheaper product and this led to Johnson taking over Aspdins Cement works at Gateshead.
- Unfortunately this resulted in an embittered Aspdin making wild and vitriolic charges of how his product had been copied.
- Johnson left J.B.
- White's shortly afterwards, and, setting up his own company, established a succession of cement plants at Frindsbury, Cliffe and Greenhithe in Kent, and acquired William Aspdin's plant at Gateshead, County Durham.
- He pioneered several innovations, including the production of low-water rawmix slurries, and new designs for kilns and industrial chimneys.
- His company remained a relatively large and successful player in the British cement industry for the next 60 years.
- The Greenhithe plant was uprated with rotary kilns in 1901.
- In 1911 I C Johnson & Co became a part of the Blue Circle Group, and his Greenhithe plant remained in operation until 1971.
- In 1910 on his 100th birthday Johnson was presented with a silver tea service by representatives of the cement industry in Britain and several European Countries. Johnson wrote the Autobiography of Isaac Charles Johnson Esq, JP (published by Farncombe & Sons, London, 1912), which was published after his death.
