Question: The author of Girl Guides, and the first Chief Scout of the Boy Scouts Association, was also the man who signed the charter to allow international scouts in which year? 
Sentence (from "International Boy Scouts, Troop 1"): International Boy Scouts, Troop 1 was founded in 1911 as Japan's first Scout troop and, despite its early multinational character, was originally registered with the London headquarters of the Boy Scouts as "British Scouts in Foreign Countries", which was the only option at the time due to the Boy Scouts' "nationality requirement" and no international Boy Scout office.
Relevant evidence: No
