I found a good link on Arthur Rayner (A.R.) Pardington who was, among other things, the referee of the first Indianapolis 500 in 1911. This role was essentially the chief steward of the race. Pardington was known as a workaholic even compromising his health with long hours and stress. He began his career as a pharmacist and then became a manager at the New York and New Jersey Telephone Company but his passion was for automobiles.
