Henry Charles Beck (4 June 1902 – 18 September 1974), known as Harry Beck, was an English technical draughtsman best known for creating the present London Underground Tube map in 1931. Beck drew up the diagram in his spare time while working as an engineering draftsman at the London Underground Signals Office. London Underground was initially sceptical of Beck's radical proposal, an uncommissioned spare-time project, but tentatively introduced it to the public in a small pamphlet in 1933.

Beck's approach to the map was to remove all geographical content except the River Thames so that the focus could be on the arrangement of lines and stations and to enable the central area to be expanded map. Beck first submitted his idea to Frank Pick in 1931 but it was considered too radical because it didn't show relative distances between stations. After a successful trial of 500 copies in 1932, distributed via a select few stations, the map was given its first full publication in 1933 (700,000 copies). It was immediately popular, and the Underground has used topological maps to illustrate the network ever since.

Beck's contribution to the visual style of London Underground is recognised with a plaque at what was his local Underground station, Finchley Central; with a blue plaque at his birth place in Leyton and the Beck Gallery at the London Transport Museum. (Full article...)
