Charles Patrick Stewart

Charles Patrick Stewart (1823 to 1882) was a British engineer and businessman, the senior partner and later chairman of the Manchester locomotive builders Sharp, Stewart and Company. According to the Institution of Mechanical Engineers obituary printed on Grace's Guide, he was born in 1823 in Dublin, where his father was occupied in the Irish administration, completed his education at Trinity College, Cambridge, and trained as a pupil in the marine engineering firm of Seward and Capel. In 1852 he became a partner in Sharp Brothers and Company at the Atlas Works in Manchester, whose style then became Sharp, Stewart and Company. The private partnership became a limited company, with Stewart as chairman, a position he held until his death at Silwood Park, Sunninghill, on 7 July 1882. He was mainly instrumental in introducing the Giffard injector to steam users in Britain, and he was a member of the Institution of Mechanical Engineers from 1859 and its vice-president from 1875.
