Charles Holden's designs for the London Underground from the mid-1920s to the outbreak of World War II represent a high point of transport architecture and Modernist design in Britain. His collaboration with Frank Pick, the Chief Executive of London Transport, brought about a marriage of form and function still celebrated today. Pick used the term 'Medieval Modernism' to describe their work on the underground system, comparing the task to the construction of a great cathedral. 'London Tube Stations 1924 - 1961' catalogues and showcases every surviving station from this innovative period. These beautiful buildings, simultaneously historic and futuristic, have been meticulously documented by architectural photographer Philip Butler. Annotated with station-by-station overviews by writer and historian Joshua Abbott, the book provides an indispensable guide to the network's Modernist gems. All the key stations have a double page spread, with a primary exterior photograph alongside supporting images. A broader historical introduction, illustrated with archival images from the London Transport Museum, gives historical context, while a closing chapter lists the demolished examples alongside further period images. These stations, as famed architectural historian Nicholas Pevsner later noted, would "pave the way for the twentieth-century style in England".
