Our reader 'Greyfox' adds: Collier had a studio at 223 Fulham Road from 1864 to 1878. (Also operated from many other addresses in that period!) .... The “Consumption Hospital” (properly “The Hospital for Consumption & Diseases of the Chest” but generally “The Brompton Hospital”) was on the opposite (north) side of Fulham Road from 1846. (I think the reference you found was to its precursor, which had been at The Manor House, Chelsea from 1842 to 1846.) The Hospital acquired houses on the South side of the road from 1868 onwards and the South Wing was completed in 1882. The Brompton was extended further in the 1970s & the original (1846) building is now a very exclusive set of apartments. The Royal Marsden building is adjacent to the South Wing of the Brompton & was opened in 1862. It was originally called “The Cancer Hospital” but was renamed in 1954 in honour of Dr Marsden, its founder.'
