Jimmie Foxx, Mel Ott.
The greatest two-player class in Hall of Fame history, Foxx and Ott combined for 1,045 career home runs, a figure surpassed by only one other duo (yet to come on this list). Just one other class of any size surpassed Foxx-Ott's homer total; 1980 inductees Al Kaline, Duke Snider and Chuck Klein combined for 1,106 homers, just 61 more than Foxx & Ott.
