Hiram Walker dedicated more than two decades to the young people involved in drum and bugle corps activity. He was director of the Osmond Post Cadets drum and bugle corps for 23 years. During that time, the corps won 7 Pennsylvania VFW State titles and 2 VFW National championships in 1948 in St. Louis, and 1949 in Miami. Their nickname, “The Hurricanes” reflected the weather conditions they experienced following their win in Miami, delaying their trip home. He founded the national Association of Junior Drum and Bugle Corps, and served as general chairman of the Veterans of Foreign Wars (VFW) Competing Drum and Bugle Corps Committee. Throughout his years of activity, he was primarily concerned about teaching corps members how to become good citizens. Many of his former Osmond Post Cadets advanced to become corps directors, judges and instructors later in life. Eight of his former members have been inducted into the World Drum Corps Hall of Fame.
