Donald Cameron Cunningham (14 August 1878 – 4 October 1942), known as Donald Colman, was a Scottish football player and coach (or trainer) in the early years of the 20th century, most notably for Aberdeen. His career in senior football did not begin until he was in his late twenties, and he was capped by Scotland at the late age of 33. As a coach, he was renowned partly as the inventor of the dugout, a sunken, sheltered area for note taking, which he introduced at Aberdeen's Pittodrie Stadium, making it the first football stadium to feature this innovation.
