Sir John Mitchell Harvey Wilson, 2nd Baronet KCVO (10 October 1898[1] – 6 February 1975[2]) was a British philatelist and Keeper of the Royal Philatelic Collection from 1938 to 1969.
In October 1936 he accepted the offer to succeed Edward Bacon, the Curator of the Royal Philatelic Collection.
Wilson knew the collection well: he visited it regularly with the RPSL Expert Committee[3] of which he was chairman from 1937 to his death.
[3] After a study of the red albums, he established that Bacon had mounted and commented on almost all acquisitions and issues up to the Edward VIII reign.
After King George VI died in 1952, he continued, alone like his two predecessors, to build the blue collection and store the issues of Elizabeth II's reign to be mounted at an appropriate future date.
