During the mid-20th century, street photography is a term normally strongly associated with Paris; but interesting street photography work was being done in other countries and cities too.
One such work was that of Thurston Hopkins who documented everyday life of post-war Britain. Hopkins worked for Picture Post, now largely-forgotten British equivalent of Life magazine. Hopkins’ obscurity is more total than that of Picture Post. As of February 2014, Hopkins does not even have a wikipedia page.
But to forget someone like Hopkins is too forget important work he did in post-war Britain; in 1950, Hopkins joined Picture Post after a stint with the RAF photographic unit during the Second World War (allegedly creating a dummy issue of Post using only his photographs and words). For the magazine, he contributed such important photoessays such as Children of the Streets in 1954, A British Colour Conflict in 1955 and Liverpool Slums in 1956. These were portraits of a bygone Britain, a traumatized post-war nation slowly coming to terms with immigration, loss of empire, and shoots of prosperity that the prime minister would dub ‘never-had-it-so-good’ in 1957.
