Harold "Fred" Fredericks, Jr. (August 9, 1929 – March 10, 2015) was an American cartoonist who drew the Mandrake the Magician comic strip from June 1965, taking over for the late Phil Davis.
Creator Lee Falk modernized the comic when Fredericks took over the strip, making it more reality-based by focusing less on science fiction and fantasy, and making Mandrake operate more like a secret agent, often helping out the police with cases they could not solve.
He was also known for writing the comic strip "Rebel" for Scholastic Magazine from 1964 to the early 1990s, and for drawing the following comic books: Nancy, Boris Karloff, The Twilight Zone, Mighty Mouse, Barney Google and Snuffy Smith, O.G.
The Mandrake Sunday page continued until the final (187th) story, "Shadows on Devil Road", ending December 29, 2002.
In 2013, Fredericks retired, and the Mandrake daily comic strip went into reprints from 1995 beginning on July 8, 2013.
