Just before Christmas, Alan Turing received a posthumous pardon.
Thanks are due to many people who campaigned to right the wrong - arguably achieved in 2009 when the UK govermnent issued an aplogy to Alan Turing. But more importantly, this pardon and the apology both directly acknowledge the tremendous impact of Turing's work. Among his many other achievements we should credit his code breaking activities as saving significant numbers of lives of the Western Allies during the Second World War.
John Graham Cumming was amongst the campaingers for the 2009 apology. One of his other interesting projects is to build the Babbage Analytical Engine. Not sure how the fund raising is going, but it's a very good cause and ground-breaking in many ways - not a reconstruction, but a first build of the machine that was never made.
