The Best Director Academy Award should actually be titled the "best achievement in directing." In the first year of the Academy Awards, there were two awards for directorship: one for direction of a dramatic film, another for comedy direction. The latter award was dropped the following year.

The Top Best Director Oscar Winners:

John Ford is the only director with 4 Best Director Oscars, followed by William Wyler and Frank Capra with 3 Best Director Academy Awards. The most nominated and most frequent winners in the Best Director category are the following:
