Famously described as the “5th Beatle”, this man lead the band to international fame as their manager:
After the departure of Allan Richard Williams, Brian Epstein helmed the wheel from 1962 up until his untimely death in 1967. Epstein died of an accidental overdose via sleeping pills that had been mixed with alcohol. It took two years for the band to hire a new, and subsequently their last, manager: Allen B. Klein.
