John Frederick Colquhoun, CBE (22 November 1890 – 28 August 1968), nicknamed "Koko",[4][5][6] was a long-serving headquarters official of The Boy Scouts Association of the United Kingdom and served on the World Organization of the Scout Movement's committee from 1959 to 1965.
At The Boy Scouts Association's Bournemouth Conference of April 1927, Colquhoun presented a paper titled 'The position of Rover leaders' which resulted in discussion on co-ordination (i.e. who was in charge) between Wolf Cubmasters, Scoutmasters and Rover leaders that led to the establishment of the Scout Group organizational structure and new rank of Group Scoutmaster from 1 January 1928.
[4][5][7][8] In the leadership changes following the death of The Boy Scouts Association's founder and first Chief Scout, Robert Baden-Powell, Colquhoun became Deputy Chief Commissioner in January 1942 and, in 1943, chairman of the General Purposes Committee, the main sub-committee of the association's committee.
[7] In 1948 Colquhoun also became The Boy Scouts Association Headquarters Commissioner for Kindred Societies (later Headquarters Commissioner for Relationships)[4] and, in that role, was the honorary organizer of the B.-P. Guild of Old Scouts from its formation in June 1948 until February 1951, after the Guild had become "autonomous" in October 1950.
Colquhoun toured Australia and New Zealand in 1950 and 1951 to inspect The Boy Scouts Association's branches.
