Humphry Repton was the successor to Capability Brown as Britains pre-eminent landscape gardener. He was renowned for inventing the Red Book. This was an artwork for prospective clients that combined hand-written design proposals with theatrical before-and-after watercolour illustrations. Nine were produced for Yorkshire clients. The talk will include Reptons commission from Earl Fitzwilliam at Wentworth Woodhouse (1791-1794), which introduced him to patronage in Yorkshire. It will then focus on those adjacent to Leeds for the new aristocrats at Harewood (1800), the industrialist, Benjamin Gott, at Armley House (1810) and the banker, John Blayds II at Oulton Hall (1810). Dr Patrick Eyres is co-author, with Karen Lynch, of On The Spot: The Yorkshire Red Books of Humphry Repton, Landscape Gardener (2018), which is now available as a PDF for a mere 10.00 from www.NewArcadianPress.co.uk. This talk is part of the Heritage Open Days Festival 2025
