Mr Editor has a post about John Simm as The Master. He is wonderful, yes. But there is and will only ever be one true Master: Roger Delgado.

Here's my Master story. A certain Roger Delgado was a member of the same synagogue I attended as a child. I cannot fully describe to you what it felt like on a Saturday morning to see, sitting ahead, the Master at prayer. To say it was a mix of sheer terror and utter fascination doesn't remotely do it justice.

(BTW, a couple of sites describe him as Catholic. He certainly wasn't listening to the Pope when we used to see him in synagogue!)
