Liberace was always going to be in showbiz
He became a pianist, vocalist, actor and WWF announcer (more on that later), but Liberace was born Władziu Valentino Liberace (or just "Lee" to his friends), which is a slightly more showy name than, say, Reginald Dwight.
Mind you, his older brother was called George, signalling that his parents knew they had to step it up name-wise if they wanted a showbiz breakthrough.
All the signs of his genius were there from an early age
Liberace was born with a caul, which, as you well know, is a piece of birth membrane that remains on the head and was thought to be an omen that the child was destined for amazingness. Other famous "caul-ists" include Lord Byron, Napoleon and, erm, James Iha, who used to be in the Smashing Pumpkins.
