On September 10, 1910, S. F. Lester of Troy, New York, became the first person to hold the Scouting leadership position of Scoutmaster (commissioned by the BSA). He received certification from scouting headquarters in New York City. He led the first thirty scouts at Camp Ilium, a Y.M.C.A. encampment at Pownal, VT. This was the first Scouting encampment for Southern Vermont. But more importantly Lester was the very first BSA trained and certified leader to conduct a BSA camp in the United States.
