a number of countries in Europe and also made one visit to the USA. The Society of Chemical Industry endowed the Hurter Memorial Lecture in his name. Personal In 1871 Hurter married Hannah Garnett of Farnworth, Widnes, with whom he had six children, one of whom died in infancy. They lived first at Prospect House in Crow Wood and later in Wilmere House, Widnes. Hurter remained a Swiss citizen throughout his life and sent his children to receive part of their education in Switzerland. He enjoyed music and played the clarinet and piano. He also took an interest in photography, collaborating in research with Vero Charles Driffield, an engineer at the Gaskell-Deacon works. Together they published many papers (in addition to Hurter's papers in chemistry). They were jointly awarded the Progress Medal of the Royal Photographic Society in 1898. The results of their research revolutionised photography. Hurter campaigned for free education and for the introduction of the metric system into Britain. He died at his home in Cressington Park, Liverpool and was buried in the churchyard of Farnworth church. His estate was valued at slightly less than £6,300.
