#2)  Most career at-bats without a home run (yes, dead ball era):
Wee Willie (Hit 'Em Where They Ain't) Keeler; ~8,500 ABs?

Dead ball era, for sure.  200-pound Catcher William Holbert had 2,335 at bats in 13 seasons and didn't hit a single home run.  He was a .208 hitter for six teams in twelve years as a backup catcher.  "Wee Willie" Keeler was just 5'4" and 140 pounds, but he hit 33 home runs in his career.

You have to give honorable mention to Giants announcer Duane Kuiper who only hit one home run in 3,259 at bats during the live ball era.
