Thanks to mechanic Ernest Holmes, Chattanooga is inextricably linked to the world of towing. Holmes invented the tow truck in 1916 in Chattanooga, Tenn. Today, those trucks are indispensable emergency vehicles throughout the world. So, it makes sense the International Towing & Recovery Museum would open here in September 1995. Over its more than 20-year history, the museum has amassed a collection that includes antique and modern tow trucks, photos and related toys. Outside the museum stands the Wall of the Fallen memorial, which includes the names of towers killed in the line of duty.
