Laverne Harding: Created the final version of Woody that was used from the mid-50s onwards.
Emery Hawkins: A notable animator during the Culhane era, and even directed one short before Shamus Culhane arrived at Lantz. While he was a serviceable director, he was a much better animator, with a slick, polished, but energetic style that perfectly suited the Woody Woodpecker shorts. One example of his animation is in "The Dippy Diplomat"; the scenes of Woody using a ping-pong racket and then eating a batch of Wally Walrus's eggs under the pretense of having lost a ping-pong ball in it are his animation.
Lester Kline: Directed several Lantz cartunes during the 1930s prior to Woody's creation, and effectively co-directed several of Paul J. Smith's efforts later in the studio's life, when Smith's eyesight problems became more pronounced.
Ed Love: Notably animated the short "Drooler's Delight" all by himself.
Alex Lovy: In addition to directing several shorts, Lovy also did some animation work on the series.
Dick Lundy: Before becoming a director, he animated a bit for Culhane on one short, "Chew Chew Baby".
Fred Moore: Normally known for his work at Disney, Moore briefly freelanced animation for a few Andy Panda and three Woody Woodpecker shorts; "Wild and Woody", "Wacky Bye Baby", and "The Mad Hatter". He notably gave Woody his third, handsomer design, which first appeared in "Musical Moments from Chopin".
Grim Natwick: Was a top animator on many of the Woody shorts during the Culhane and Lundy era. He notably animated the entire climax sequence of "Chew Chew Baby", as well as entirely animating the chicken from "Solid Ivory". He also animated the climatic scene of Wally Walrus hassling with his haywire bed in "Smoked Hams". His drawing style is very easy to spot, as he tends to draw more rough and loosely than the other animators (one dead giveaway is the way he draws eyes on his characters).
Cash Cow Franchise: Woody Woodpecker was this once upon a time, enough to have many comics and merchandising tie-ins. Nowadays, you'll be lucky to even see him outside of a mascot theme park costume or his DVD re-releases.
Descended Creator: Ben Hardaway, Woody's co-creator, provided the voice for Woody for the bulk of his 1940's cartoons.
Shamus Culhane — Made his bow on the series with 1944's "The Barber of Seville," and continued until 1946's "Fair Weather Fiends." Usually regarded as the best director on the series by those who prefer more brutal Tom and Jerry style comedy in the cartoons. Despite being highly regarded, his tenure on the series was surprisingly brief, only directing 10 shorts.
Jack Hannah — Showed up in 1960, following Alex Lovy's final departure from the studio. Probably the least well-remembered of Woody's directors, although his work is generally regarded as being better than what Paul J. Smith was doing at the time. His last cartoon was 1962's "Voodoo Boodoo". He directed 8 shorts total.
Ben Hardaway: Sole effort was co-directing "The Dizzy Acrobat" with Lantz and Lovy.
Emery Hawkins & Milt Schaffer — Directed one cartoon, 1943's "Ration Bored," between the departure of Alex Lovy and the arrival of Shamus Culhane.
Walter Lantz — Handled a few early cartoons, although exactly which ones is up for debate. He definitely directed a number of cartoons in 1951 following Dick Lundy's departure. Like Lovy, the cartoons he (supposedly) directed in the 40s aren't too well regarded, but his 1951 efforts benefited from him maintaining the animation standards of Dick Lundy. He directed 16 shorts total, and co-directed "Dizzy Acrobat" with Lovy and Hardaway.
Alex Lovy — Directed Woody's debut cartoon, in addition to providing his original design, and handled most of Woody's early shorts until 1943. He later returned in 1956, before leaving for good in 1960. His shorts tended to be the most derivative of Warner Bros. shorts, although they often suffered from mushy timing and even pacing. All in all, his 40's shorts are not highly regarded, but his 50's works tend to be considered better. He directed 12 shorts on his own, and co-directed "Dizzy Acrobat" with Lantz and Hardaway.
Dick Lundy — Started working on the series with 1946's "Bathing Buddies," and carried on until the studio's hiatus in 1949. His work was by far the most technically accomplished of all Woody's directors, and his cartoons had a pacing and timing style that found the sweet spot between Lovy and Culhane's work. Directed 13 shorts on his own, and co-directed one of them.
Sid Marcus — Better known as a storyboard artist, though he also worked as a director at the studio from 1963 until 1967. Like Hannah, his work isn't particularly well remembered (mostly because he actually directed more Chilly Willy cartoons than Woody Woodpecker ones), but is held in higher regard than that of Paul J. Smith. He directed 14 shorts.
Don Patterson — Took over as the primary director between 1951 and 1954. He had a very similar style to Lundy, albeit with a bit less polish. Sadly, he was demoted to being an animator in order to make way for the returning Tex Avery (who subsequently left the studio without directing a Woody Woodpecker cartoon and in turn was replaced by Alex Lovy, who himself was returning to the studio). He directed 14 shorts total.
Paul J. Smith — The most prolific director of Woody Woodpecker cartoons — and indeed, Walter Lantz cartoons in general — but also generally regarded as the worst. His first effort on the series was 1955's "Helter Shelter," and continued all the way through to the last ever Lantz cartoon, 1972's "Bye Bye Blackboard." Although his first few cartoons were generally quite solid, his work suffered particularly badly from cost-cutting as the the 1960s went on. He directed 109 shorts total, and one of Woody's cameos in a Chilly Willy short.
Mel Blanc — Woody's original voice actor, who developed Woody's voice from a rejected one he originally did for Bugs Bunny. He left after the first two shorts when he signed an exclusive contract with Warner Bros., though his version of Woody's laugh and many of the other vocal effects he did would continue to be used for years afterwards.
Ben Hardaway — In addition to being Woody's co-creator, he provided his voice for 1941's "The Screw Driver," and then became Woody's permanent voice starting with 1944's "The Beach Nut", continuing until the studio's temporary shutdown in 1949.
Kent Rogers — Woody's first long-term voice actor, who began with 1942's "Ace in the Hole" and carried on until "The Barber of Seville" two years later. His tenure as Woody's voice ended in tragic circumstances, as he was drafted into the navy in mid-1944, only to be killed just a few weeks into his tour of duty.
Grace Stafford — The longest-serving voice for Woody, and also Walter Lantz's wife. Her earliest confirmed cartoon is 1952's "Stage Hoax" (though it's thought that she may have occasionally deputized for Hardaway in the previous decade), and she carried on until the final Walter Lantz cartune, "Bye Bye, Blackboard" in 1972. Even then she continued voicing Woody in commercials and television specials until the early 1990s.
Danny Webb — Another short-lived voice of Woody, who only performed the role for "Pantry Panic" and "The Hollywood Matador" in 1941 and 1942 respectively, though continued to voice other, minor roles in Woody's cartoons for several more years.
Billy West — did several voices in the newer series, including the voice of Woody himself.
Development Hell: The Illumination Woody Woodpecker feature was initially slated for a 2015 release, but as of late 2015, it hasn't even entered production yet.
Keep Circulating the Tapes: All of the original shorts from the 1940s to around the mid 1950s are available on DVD collections with some shorts from other Walter Lantz series sandwiched in, but there are currently no plans for a release of the remaining cartoons; and this is just the original cartoons as shown in theaters, not the versions with live action intermissions that aired on the original Woody Woodpecker Show (while both of the officially DVD sets include several of these excerpts as extras, its not all of them). Likewise, there are no plans for a rerelease of The New Woody Woodpecker Show either, or any dvd releases of Walter Lantz's other animated properties.
As of now, only one episode of The New Woody Woodpecker Show ("Frankenwoody/The Meany Witch Project/Fright Movie Woody") has been released on DVD as as a bonus feature on Woody Woodpecker and Friends Halloween Favorites.
The Other Darrin: As mentioned above, Woody has gone through several different voice actors, although voice clips from his original actor, Mel Blanc, were used up to the 1950's shorts.
