Founding Story
In 1966, Richard M. Schulze and James Wheeler opened Sound of Music in Saint Paul, Minnesota. In 1981, a devastating tornado ripped the roof off their largest location. Schulze held a massive 'Tornado Sale' in the parking lot, slashing prices to the bare minimum. The overwhelming consumer response inspired the 1983 rebranding to Best Buy.
