Robert Stevenson

Born 8 Jun 1772; died 12 Jul 1850 at age 78. Scottish civil engineer who in 1797 succeeded his stepfather, Thomas Smith, as a member of the Scottish Lighthouse Board. In that capacity until 1843, he designed and built lighthouses (1797-1843). His first and greatest was the lighthouse at Bell Rock. Subsequently he established a civil engineering practice involved at first in canal, road and rail projects, and later maritime, river and bridge work. As chief executive of the Northern Lighthouse Board (1808-43) he was responsible for the construction and design of at least 23 lighthouses on the Scottish Coastline. He invented intermittent and flashing lights as well as the hydrophore (an instrument for obtaining specimens from water). The writer Robert Louis Stevenson was his grandson.
