John Milne (1823 - 1904) was a Scottish architect operating throughout the second half of the 19th century, working largely in the Fife area. He was described as an ‘’inventive neo-Jacobean and Scots Baronial designer’’. He exhibited works at the Royal Scottish Academy in the 1860s. He was also an inventor of a pyro-pneumatic grate: a heating system for churches. He self-financed several improvement schemes to the town of St Andrews
