I would like to wish a very Happy Birthday to the wonderful Thomas "Tom" Baker! He turns 79 today (( January 20th 1934)). Here is to many more birthdays to come! :) My fellow Whovians know him as the 4th Doctor on Doctor Who . He played the Doctor for the longest so far. Also for my Sherlockians, he played Sherlock Holmes in a 1982 miniseries "The Hound of the Baskervilles."
