Bruce Walter Timm (born on February 8, 1961) is an American character designer, animator and producer. He is also a writer and artist working in comics, and is known for his contributions building the modern DC Comics animated franchise, the DC animated universe.

Timm's early career in animation was varied; he started at Filmation, working on the layout of Blackstar, Flash Gordon, He-Man and the Masters of the Universe and its spin-off She-Ra: Princess of Power, and The Lone Ranger (Timm also did background work on G.I. Joe). He also worked for numerous other employers, including Ralph Bakshi, Don Bluth Productions, and attempted to find work at Marvel Comics and DC Comics, but without luck. In 1989, Timm joined Warner Bros. At Warner, Timm worked on Tiny Toon Adventures.

However, Timm is best known for his subsequent work on the animated series based on various DC Comics superheroes, popularly referred to as the "DCAU" (DC animated universe). Along with his Tiny Toons partner Eric Radomski, Timm co-created and produced Batman: The Animated Series, which premiered on September 5, 1992, and went on to co-create and produce Superman: The Animated Series (premiered in September 1996), The New Batman Adventures (premiered in September 1997), and Batman Beyond (premiered in January 1999). He also served as producer on the feature-length Batman Beyond: Return of the Joker before taking the helm as creator and producer of the animated version of Justice League, which debuted in November 2001. This series continued in the form of Justice League Unlimited. Timm actually had very little to do with the production of the Teen Titans animated series, though because of a mistake in the first season end credits he is often mistaken for an executive producer. Timm was also the producer and co-director of the direct-to-video Superman Doomsday.

Alan Burnett is a television writer-producer particularly associated with Warner Bros. Animation, Hanna-Barbera Productions, DC Comics and Walt Disney television animation. He has had a hand in virtually every DC animated project since the waning years of the Super Friends, and continues to do so as of 2012^[update]. Burnett's contributions for Disney were largely a part of the 1990s Disney Afternoon, where he was attached to the Disney's Adventures of the Gummi Bears and various projects set in the Scrooge McDuck universe. Because of his primary focus on televised animation, he has occasionally been involved in film projects related to a parent television program. He is a graduate of the University of Florida and has an MFA in film production from the University of Southern California.

Burnett has won four Emmys for his work in television as well as three Annie Awards, two Humanitas Awards, and an Animation Writer of the Year Award from the Writers Guild of America.

He has worked on many television shows, from The Smurfs and DC animated series "Superfriends and The Super Power Team"and Batman: The Animated Series, to the Batman Beyond animated series and The Batman. Burnett also wrote a segment in Batman: Gotham Knights (a series of 6 animated short films bridging the gap between the movies Batman Begins and The Dark Knight).

Winsor McCay (September 26, 1869 – July 26, 1934) was an American cartoonist and animator.

A prolific artist, McCay's pioneering early animated films far outshone the work of his contemporaries, and set a standard followed by Walt Disney and others in later decades. His two best-known creations are the newspaper comic strip Little Nemo in Slumberland, which ran from 1905–1914 and 1924–1927, and the animated cartoon Gertie the Dinosaur, which he created in 1914.

His comic strip work has influenced generations of artists, including creators such as William Joyce, André LeBlanc, Moebius, Maurice Sendak, Chris Ware and Bill Watterson.

McCay was the son of Robert McKay (later changed to McCay) and Janet Murray McKay; Robert at various times worked as a teamster, a grocer, and a real estate agent. Winsor's exact place and year of birth are uncertain — he claimed to have been born in Spring Lake, Michigan in 1871, but his gravestone says 1869, and census reports state that he was born in Canada in 1867. He was originally named Zenas Winsor McKay, in honor of his father's employer, Zenas G. Winsor. He later dropped the name Zenas.
