H. Oswald "Os" Doenges (October 18, 1905 – March 1987) was an American football player and coach.
Doenges was known for his creativity in the sport with several attempts to improve the game by making it faster and more enjoyable to watch.
The first was a success—as he worked with Dike Beede to test the use of the penalty flag by officials in the 1941 Oklahoma City vs. Youngstown football game.
[1] Doenges is credited with inventing the offensive V formation, nicknamed "Three dots and a dash" (Morse code for the letter "v").
His Oklahoma City program presented the new offensive formation to great fanfare before losing to the Southwestern Moundbuilders by a score of 7–0.
