==Biography==
Saxby was born at Brighton on 17 August 1821 and in 1834 was apprenticed at the age of thirteen to a carpenter and joiner. In 1840 he was employed as a carpenter at the Brighton railway works of the London and Brighton Railway to make oak mile-posts, and where he designed a tool to automate their production. He later became the foreman of the carpenters and joiners, sawyers, pattern makers, plumbers, gas-fitters, and labourers at the works.
