In 1816 John Claudius Loudon patented a wrought-iron glazing bar. It was developed by W. and D. Bailey, of Holborn in London. In 1818, they entered a patent on the invention, and during the 1820s and 1830s they erected a number of remarkable curvilinear glasshouses. One of the earliest surviving examples was erected in 1820 at Downton Castle in Shropshire for Thomas Andrew Knight, second President of the Royal Horticultural Society.[1]
