"The Claudians" by Tom Turner: https://www.amazon.com/dp/B0DJL69B9H John Claudius Loudon wrote more than anyone who lived before him and was the prolific inventor of: an improved furnace, the term "arboretum", the landscape architecture profession, curvilinear glass and steel buildings, breathing zones, urban transport planning, the gardenesque style of planting design, magazines on gardening and architecture, systematic garden history. Sir William Hooker, the first director of Kew Gardens, wrote of his "Arboretum Britannicum" that: ‘There is not a naturalist in Europe who could have executed the task with anything like the talent and judgement and accuracy that is here displayed by Mr Loudon’. On the title pages of the various editions of his "Encyclopaedia of Gardening" Loudon followed his name with FLS and HS. He took pride in being a Fellow of the Linnean Society and a member of the Horticultural Society. The HS was established in 1804 and became the Royal Horticultural Society (RHS) in 1861. Sir Joseph Banks (a friend and patron of Loudon) and John Wedgwood (son of Josiah) founded the Horticultural Society of London. It was dedicated to the promotion of horticulture and botanical science.
