(written from a Production point of view)
Robert Albert Bloch (5 April 1917 – 23 September 1994; age 77) was a legendary American horror writer whose perhaps best known for writing the 1959 novel Psycho, which was filmed one year later by Alfred Hitchcock (featuring John Anderson and Ted Knight). He penned numerous other novels, stories, screenplays and teleplays, some set in the infamous Cthulhu setting created by horror master H. P. Lovecraft, with whom he was a frequent correspondent.
He penned three original series episodes. Two of these were based on short stories written by him previously. "Catspaw" was loosely based on his 1957 story Broomstick Ride, while "Wolf in the Fold" was adapted from the 1943 story Yours Truly, Jack the Ripper, which was previously adapted to an episode of Thriller in 1961. Two of his episodes ("What Are Little Girls Made Of?" and "Catspaw") make mentions of the "Old Ones", a term frequently used by Lovecraft in his stories.
