Born: April 30, 1947
Famous for: Being the baddest of a bad lot in London's East End
As the original "Dirty Den", he set the standard for every villain who has darkened the streets of Albert Square. And he managed to set the bar so high that few of the soap's many reprobates have measured up since. Leslie has also appeared in movie and theatre productions, but he'll always be best-remembered as Walford's baddest bad-boy.
