The Royal College of Nursing (founded in 1916 with 34 members, but now with 440,000) is busy celebrating its centenary; and, at its grand headquarters in London’s Cavendish Square, there was another little celebration last week. This was to mark the centenary of a small, short-lived and generally unremembered medical institution, the Anglo-Russian Hospital of St Petersburg, at which some 6,000 wounded Russian soldiers were treated by British doctors and nurses during the last two years of the first world war.
