Bobby Cox, recently retired manager of the Atlanta Braves, holds the MLB record for ejections with 158 regular-season ejections. If you add his 3 postseason ejections, his total is 161 for his career.
Anyone with zero ejections, and there are many players with that number.
William "Bad Bill" Dahlen (b. 1870, played 1891-1911, managed 1910-1913) is the unofficial record holder, in a category in which stats are woefully maintained. It doesn't even seem to be all that close, though. Dahlen also got ejected quite frequently as a manager, in an admittedly short stint.
