This week is Scout Week, a celebration of 97 years of scouting in the United States. It began on Feb. 4th and ends on Feb. 10th.
The Boy Scouts of America was established in 1910 by William D. Boyce. The story of how Boyce came to be interested in Scouting has appeared in various forms. All versions agree on the following: Boyce, a publisher from Chicago, was lost in London's famous fog when he was met by a boy who showed him the way to his destination; the boy then refused an offer of payment for his services. Some assert that the boy vanished into the fog after refusing Boyce's money and never saw him again, but others declare that the two arranged another meeting, so that the boy could show Boyce to the headquarters. Still others hold that the boy was uniformed at the time. The truth of the matter is shrouded in years of Scouting legend and may never be known for sure.

Some versions claim that Boyce actually knew about Scouting before this event, that the place he was seeking in the fog was actually Scouting headquarters, and that he had in fact come to London to learn more about the organization. (Baden-Powell was associated with the British YMCA; news of the Boy Scouts had reached the U.S. through this organization.)
Boyce returned to the United States and, with Edward S. Stewart and Stanley D. Willis, incorporated the Boy Scouts of America on February 8. The first troop was Troop 1, based at a YMCA. Edgar Robinson, an important administrator of the YMCA in Chicago, agreed to help Boyce organize the Boy Scouts as a national organization.
In 1910, Seton, Beard, Baden-Powell, Boyce, Robinson and others called a national meeting of people involved in youth work. The first national officers of the BSA were selected. It was agreed that the President of the United States (then William Howard Taft) was to be the Honorary President of the BSA, a tradition that is still followed today.
