Eddie Murphy (Confirmed- not a Freemason. Confused with Audie Murphy who is a war hero and also an actor)
Best known as: A comedian
Member of: North Hollywood Lodge No. 542, CA (see note below)
Quotable Quote: “In reality, all men are sculptors, constantly chipping away the unwanted parts of their lives trying to create a masterpiece.”
Note: Though Eddie Murphy is listed as a Freemason in numerous Masonic websites (including Wikipedia's list of Famous Freemasons). I couldn't find any record of the date when he was Initiated, Passed, and Raised. I also wonder if some people have just confused him with Freemason Audie Murphy (1924-1971) of Hollywood Lodge No. 542, CA.
EDIT (June 25, 2012): Bro. Jeff M., a member of North Hollywood Lodge No. 542 and Ken Butters confirmed that I (and wikipedia) have confused Audie Murphy with Eddie Murphy. Audie Murphy and not Eddie Murphy is a member of North Hollywood Lodge No. 542 where they have a special room dedicated in his memory.
