William Carpmael

William Carpmael (27 February 1804 - 9 July 1867) was a civil engineer and lawyer.

Born in London, Carmael pursued a varied career in commerce and as laboratory assistant before undertaking training in engineering under Professor John Millington. In 1830 he became as associate of the Institution of Civil Engineers. He was also a member of the Royal Institution, the Institution of Mechanical Engineers and the Institution of Naval Architects.

In 1835 he established himself as a patent agent and consulting engineer, and became a member of Lincoln's Inn. From that date he confined himself to the legal rather than practical aspects of engineering.

When the first Metropolitan Board of Works was formed in December 1855 Carpmael was elected as representative of Wandsworth District Board of Works. He remained a member until his death, taking an active interest in the main drainage and Thames Embankment projects of the Metropolitan Board.
