Back to the Future: The impact of science across Essex – Gas Manufacture and Water Purification

In our last blog post we introduced you to Dr David Crease, one of the speakers for our day long science conference on March 7th. Next up we would like to introduce you to Peter Wynn, who will be giving two talks: one about gas manufacture and one about water purification.

Peter is a retired senior lecturer of civil engineering at Anglia Ruskin University and a fellow of the Chartered Institution of Water and Environmental Management. He has long held an interest in gas manufacture in Essex, having discovered papers from 1947 relating to issues with the Chelmsford gas holder’s foundations.

Though the dangers of unsanitary water supply were proved by Dr John Snow in 1854, his findings were not widely believed until after his death when the bacteria causing cholera was isolated in the 1880s.

In 1895, when John Clough Thresh became the Medical Officer of Health for Essex, the purification of water for human consumption was still very much a challenge. Well beyond his retirement, Thresh continued to act as a consultant for Essex County Council until his death in 1932. His work to improve the water supply for his adoptive county was considered pioneering by both his peers and by more recent researchers alike. His influence extended well beyond Essex.

Commercial supply of gas in the UK began in the early 19th century, originally by way of small gas plants installed in the premises where the gas was to be used. Following the formation of the Chartered Gas Light and Coke Company in London in 1812, pioneers of public gas supply, many other companies were founded; including in Chelmsford in 1819.
