'''Ubbe Ert''' "'''Ub'''" '''Iwerks''' ({{IPAc-en|ʌ|b|_|ˈ|aɪ|w|ɜr|k|s}} {{respell|ub|_|EYE|wurks}}; March 24, 1901&nbsp;– July 7, 1971), was an American [[animator]], [[cartoonist]], [[character designer]], [[Invention|inventor]], and [[special effects]] [[technician]], known for his work with [[Walt Disney Animation Studios]] in general, and for having worked on the development of the design of the character of [[Mickey Mouse]], among others. Born in [[Kansas City, Missouri]], Iwerks met fellow artist [[Walt Disney]] while working at a Kansas City art studio in 1919. 

After briefly working as illustrators for a local newspaper company, Disney and Iwerks ventured into animation together. Iwerks joined Disney as chief animator on the [[Laugh-O-Gram]] shorts series beginning in 1922, but a studio bankruptcy would cause Disney to relocate to [[Los Angeles]] in 1923. In the new studio, Iwerks continued to work with Disney on the ''[[Alice Comedies]]'' as well as the creation of the [[Oswald the Lucky Rabbit]] character. Following the first ''Oswald'' short, both Universal Pictures and the Winkler Pictures production company insisted that the Oswald character be redesigned. At the insistence of Disney, Iwerks designed a number of new characters for the studio, including designs that would be used for [[Clarabelle Cow]] and [[Horace Horsecollar]].

One of Iwerks' most long-lasting contributions to animation was a refined version of a sketch drawn by Disney that would later go on to become [[Mickey Mouse]]. Iwerks was responsible for much of the animation for the early Mickey Mouse and ''[[Silly Symphony]]'' cartoons, including ''[[Steamboat Willie]]'', ''[[The Skeleton Dance]]'' and ''[[The Haunted House (1929 film)|The Haunted House]]'', before a falling out with Disney led to Iwerks' resignation from the studio in January 1930. Iwerks' final ''Mickey Mouse'' cartoon was 1930's ''[[The Cactus Kid (1930 film)|The Cactus Kid]]''. Following his separation with Disney, Iwerks, operating under [[Iwerks Studio]], created the characters [[Flip the Frog]] and [[Willie Whopper]] along with the ''[[ComiColor Cartoons]]'' series as part of a contract with [[Metro-Goldwyn-Mayer]], but the new studio failed to rival its competitors. Iwerks later directed two ''[[Looney Tunes]]'' cartoon shorts for [[Leon Schlesinger Productions]] and several ''[[Color Rhapsody]]'' cartoons for [[Screen Gems]] before joining Disney again in 1940, after which he worked with special visual effects on productions such as 1946's ''[[Song of the South]]''.

Iwerks had two children, [[Don Iwerks|Donald Warren Iwerks]] and David Lee Iwerks, with his wife Mildred Sarah Henderson. Iwerks died of a heart attack in [[Burbank, California]], in 1971 at age 70. Iwerks was posthumously named a [[Disney Legend]] in 1989. His likeness has been featured in his granddaughter [[Leslie Iwerks]]' 1999 documentary ''The Hand Behind the Mouse: The Ub Iwerks Story'' as well as the 2014 feature film ''[[Walt Before Mickey]]'', in which he is portrayed by [[Armando Gutierrez]]. Iwerks received three nominations at the [[Academy Awards]], for which he won one. He also posthumously received the [[Winsor McCay Award]] at the 1978 [[Annie Awards]] and the Hall of Fame award at the 2017 [[Visual Effects Society Awards]].

== Early life ==
Iwerks was born in [[Kansas City, Missouri]].{{sfn |Lenburg |1993 |p=[https://archive.org/details/greatcartoondire00lenb/page/24/mode/2up 25]}} His father was born in the village of [[Uttum]] in [[East Frisia]] (northwest Germany, today part of the municipality of [[Krummhörn]]) and emigrated to the United States in 1869 around the age of 14.<ref>{{Cite web |title=Ub Iwerks {{!}} American Animator and Special-Effects Technician |url=https://www.britannica.com/biography/Ub-Iwerks |url-status=live |archive-url=https://web.archive.org/web/20170910084220/https://www.britannica.com/biography/Ub-Iwerks |archive-date=September 10, 2017 |access-date=December 26, 2021 |website=[[Britannica.com]] |language=en}}</ref> The elder Iwerks, who worked as a barber, had fathered and abandoned several previous wives and children. When Ub was a teenager, his father abandoned him as well, forcing the boy to drop out of school and work to support his mother. Iwerks despised his father and never spoke of him; upon learning that he had died, he reportedly said, "Throw him in a ditch."{{sfn |Iwerks |Kenworthy |2001 |p=134}} He attended Ashland Grammar School, graduating in 1914.{{sfn |Lenburg |1993 |p=[https://archive.org/details/greatcartoondire00lenb/page/24/mode/2up 25]}}  Ub's full name, Ubbe Ert Iwwerks, can be seen on early ''[[Alice Comedies]]'' that he signed. Several years later, he simplified his name to "Ub Iwerks", sometimes written as "U.B. Iwerks".{{efn|For example in the opening credits of ''[[Little Black Sambo (film)|Little Black Sambo]]'' (1935)}}

==Career==
===Disney work (1919–1929)===
Iwerks spent most of his career with Disney. The two met in 1919 while working for the Pesmen-Rubin Art Studio in Kansas City,{{sfn |Gabler |2006 |p=46}} and eventually started their own commercial art business together.{{sfn |Gabler |2006 |pp=47–50}} Disney and Iwerks then found work as illustrators for the Kansas City Slide Newspaper Company{{sfn |Gabler |2006 |p=50}} (which was later named The Kansas City Film Ad Company).{{sfn |Gabler |2006 |p=56}} While working for the Kansas City Film Ad Company, Disney decided to take up work in animation,{{sfn |Gabler |2006 |p=58}} and Iwerks soon joined him. There he{{who|Disney or Iwerks?|date=April 2025}} attached a motor drive to the camera with a switch that resembled a telegraph key, reducing the number of people needed to animate from two to just one.{{how|reason=Both how and what here are opaque: what camera?

[[File:Trolley Troubles (1927) Title Card.jpg|thumb|The title card for ''[[Trolley Troubles]]'' (1927), animated by Iwerks]]

Iwerks was responsible for the distinctive style of the earliest Disney [[animated cartoon]]s, and was also responsible for designing Mickey Mouse.{{sfn |Maltin |1987 |p=189}} In 1922, when Disney began his [[Laugh-O-Gram Studio|Laugh-O-Gram]] cartoon series, Iwerks joined him as chief animator. The studio went bankrupt, however, and in 1923 Iwerks followed Disney's move to Los Angeles to work on a new series of cartoons known as "the [[Alice Comedies]]" which had live-action mixed with animation. After the end of this series, Disney asked Iwerks to design a character that became [[Oswald the Lucky Rabbit]].{{sfn |Apgar |2015 |pp=[https://archive.org/details/mickeymouseemble0000apga/page/34/mode/2up 34]–[https://archive.org/details/mickeymouseemble0000apga/page/36/mode/2up 37], [https://archive.org/details/mickeymouseemble0000apga/page/60/mode/2up 61]}} The first cartoon Oswald starred in was animated entirely by Iwerks. Following the first cartoon, Oswald was redesigned on the insistence of Oswald's owner and the distributor of the cartoons, Universal Pictures. The production company at the time, Winkler Pictures, gave additional input on the character's design.

In spring 1928, Disney was removed from the Oswald series, and much of his staff was hired away to Winkler Pictures. He promised to never again work with a character he did not own.{{sfn |Gabler |2006 |p=109}} Disney asked Iwerks, who stayed on, to start drawing up new character ideas. Iwerks tried sketches of frogs, dogs, and cats, but none of these appealed to Disney. A female cow and male horse were created at this time by Iwerks, but were also rejected. They later turned up as [[Clarabelle Cow]] and [[Horace Horsecollar]].{{sfn |Gabler |2006 |p=53}} Ub Iwerks eventually got inspiration from an old drawing. In 1925, [[Hugh Harman]] drew some sketches of mice around a photograph of Walt Disney. Then, on a train ride back from a failed business meeting, Walt Disney came up with the original sketch for the character that was eventually called [[Mickey Mouse]].{{sfn |Iwerks |Kenworthy |2001 |p=54}}{{sfn |Apgar |2015 |p=[https://archive.org/details/mickeymouseemble0000apga/page/76/mode/2up 76]}} Afterward, Disney took the sketch to Iwerks. In turn, he drew a more clean-cut and refined version of Mickey, but one that still followed the original sketch.{{sfn |Apgar |2015 |pp=[https://archive.org/details/mickeymouseemble0000apga/page/80/mode/2up 80–81]}}

[[File:Excerpt from Steamboat Willie (1928), used as part of Walt Disney Animation Studios Logo.gif|thumb|right|Excerpt of ''[[Steamboat Willie]]'' (1928), one of the first few Mickey Mouse shorts, which was animated almost entirely by Iwerks]]

The first few Mickey Mouse and ''[[Silly Symphony]]'' cartoons were animated almost entirely by Iwerks, including ''[[Steamboat Willie]]'', ''[[The Skeleton Dance]]'' and ''[[The Haunted House (1929 film)|The Haunted House]]''.{{sfn |Maltin |1987 |p=189}} However, as Iwerks began to animate more and more cartoons on a daily basis, he chafed under Disney's leadership.{{sfn |Gabler |2006 |p=143}} Iwerks also felt he was not getting the credit he deserved for drawing all of Disney's successful cartoons.{{sfn |Gabler |2006 |p=144}} Eventually, Iwerks and Disney had a falling out; their friendship and working partnership were severed in January 1930. According to an unconfirmed account, a child approached Disney and Iwerks at a party and asked for a picture of Mickey to be drawn on a napkin, to which Disney handed the pen and paper to Iwerks and stated, "Why don't you draw Mickey and I'll sign it." Iwerks became furious and threw the pen and paper, storming out.{{sfn |Iwerks |Kenworthy |2001 |pp=83-84}}<ref>{{Cite web |last=Not! |first=Ripley's Believe It or |title=Wonderfully Weird Facts You Want To Know About Walt Disney |url=https://lethbridgenewsnow.com/2020/08/18/wonderfully-weird-facts-you-want-to-know-about-walt-disney/ |access-date=May 7, 2023 |website=Lethbridge News Now |language=en}}</ref> Iwerks accepted a contract with Disney's former distributor, [[Pat Powers (businessman)|Pat Powers]], to leave Disney and start an animation studio under his own name.<ref>{{Cite book |last1=Kaufman |first1=J.B. |title=Walt Disney's Mickey Mouse: The Ultimate History |last2=Gerstein |first2=David |date=2018 |publisher=Taschen |isbn=978-3-8365-5284-4 |location=Cologne |page=53}}</ref> His last Mickey Mouse cartoon was ''[[Wild Waves]]'' (1929) and final Disney film was the Silly Symphony ''[[Autumn (1930 film)|Autumn]]'' (1930).<ref>{{Cite book |last=Ryan, Jeff |title=A Mouse Divided: How Ub Iwerks Became Forgotten, and Walt Disney Became Uncle Walt |publisher=Post Hill Press |year=2018 |isbn=978-1-68261-628-4 |pages=181, 184}}</ref> (Powers and Disney had an earlier falling-out over Disney's use of the Powers Cinephone [[sound-on-film]] system—actually copied by Powers from [[Lee de Forest|DeForest]] [[Phonofilm]] without credit—in early Disney cartoons.){{citation needed|date=December 2022}}

=== After Disney (1930–1940) ===
====Iwerks Studio====
{{main article|Iwerks Studio}}
The [[Iwerks Studio]] opened in 1930. Financial backers led by Pat Powers suspected that Iwerks was responsible for much of Disney's early success. However, while animation for a time suffered at Disney from Iwerks' departure, it soon rebounded as Disney brought in talented new young animators.{{cn|date=April 2025}}

Despite a contract with MGM to distribute his cartoons, and the introduction of a new character named [[Flip the Frog]] and later [[Willie Whopper]], the Iwerks Studio was never a major commercial success and failed to rival either Disney or [[Fleischer Studios]].  Newly hired animator Fred Kopietz recommended that Iwerks employ a friend from Chouinard Art School, [[Chuck Jones]], who was hired and put  to work as a cel washer.{{sfn |Maltin |1987 |p=191}} The Flip and Willie cartoons were later distributed on the home-movie market{{clarification needed| date= March 2019}} by [[Official Films]] in the 1940s.

[[File:Sinbadthesailor01.jpg|thumb|upright|''[[Sinbad the Sailor (1935 film)|Sinbad the Sailor]]'', a 1935 ComiColor cartoon]]
From 1933 to 1936, he produced a series of shorts (independently distributed, not part of the MGM deal) in [[Cinecolor]], named ''[[ComiColor Cartoons]]''. The ComiColor series mostly focused on fairy tales with no continuing character or star. Later in the 1940s, this series received home-movie distribution by [[Castle Films]]. Cinecolor produced the 16&nbsp;mm prints for Castle Films with red emulsion on one side and blue emulsion on the other. Later in the 1970s [[Blackhawk Films]] released these for home use, but this time using conventional Eastmancolor film stock. They are now in the public domain and are available on VHS and DVD. He also experimented with stop-motion animation in combination with the [[multiplane camera]], and made a short called ''The Toy Parade'', which was never released in public.<ref>{{Cite book |last=Telotte |first=J. P. |url=https://books.google.com/books?id=LEy50gAEhpgC&dq=unreleased+film+Toy+Parade&pg=PA62 |title=The Mouse Machine: Disney and Technology |year=2008 |publisher=University of Illinois Press |isbn=9780252033278 |author-link=Jay Telotte |via=Google Books}}</ref> In 1936, backers withdrew financial support from the Iwerks Studio, and it folded soon after.

====Contract work====
In 1937, [[Warner Bros. Cartoons|Leon Schlesinger Productions]] contracted Iwerks to produce four ''[[Looney Tunes]]'' shorts starring [[Porky Pig]] and [[Gabby Goat]]. Iwerks directed the first two shorts, while former Schlesinger animator [[Robert Clampett]] was promoted to director and helmed the other two shorts before he and his unit returned to the main Schlesinger lot. Iwerks then did contract work for [[Screen Gems]] (then [[Columbia Pictures]]' cartoon division)  where he was the director of several of the ''[[Color Rhapsody]]'' shorts before returning to work for Disney in 1940.

=== Return to Disney (1940–1964) ===
After his return to the Disney studio, Iwerks mainly worked on developing [[special effects|special visual effects]]. He is credited as developing the processes for combining live-action and animation used in ''[[Song of the South]]'' (1946), as well as the [[Xerography|xerographic]] process adapted for cel animation, which was used in ''[[One Hundred and One Dalmatians|101 Dalmatians]]'' (1961).<ref name=korkis/> He also worked at WED Enterprises, now [[Walt Disney Imagineering]], helping to develop many Disney theme park attractions during the 1960s. Iwerks did special effects work outside the studio as well, including the birds for his [[Academy Awards|Academy Award]] nominated achievement for [[Alfred Hitchcock]]'s ''[[The Birds (film)|The Birds]]'' (1963).<ref name="Cinefantastique-Counts-Birds">{{Cite news |last1=Counts |first1=Kyle B. |last2=Rubin |first2=Steve |date=Fall 1980 |title=The Making of Alfred Hitchcock's The Birds |volume=10 |work=[[Cinefantastique]] |issue=2 |url=https://the.hitchcock.zone/wiki/Cinemafantastique_(1980)_-_The_Making_of_Alfred_Hitchcock's_The_Birds |url-status=live |access-date=March 7, 2022 |archive-url=https://web.archive.org/web/20220307154006/https://the.hitchcock.zone/wiki/Cinemafantastique_%281980%29_-_The_Making_of_Alfred_Hitchcock%27s_The_Birds |archive-date=March 7, 2022}}</ref> Iwerks' last credit for Disney was for perfecting the travel matte system for the ''Mary Poppins'' sequence "Feed the Birds"<ref name=korkis/> Iwerks' most famous work,<ref name=korkis/> outside animating Mickey Mouse, was Flip the Frog from his own studio.<ref>{{Cite web |last=Marks |first=Scott |date=May 19, 2016 |title=Fiddlesticks Flips Flip in First Color Cartoon |url=https://www.sandiegoreader.com/news/2016/may/19/screen-fiddlesticks-flips-flip-first-color-cartoon/ |url-status=live |archive-url=https://web.archive.org/web/20220502182312/https://www.sandiegoreader.com/news/2016/may/19/screen-fiddlesticks-flips-flip-first-color-cartoon/ |archive-date=May 2, 2022 |access-date=May 2, 2022 |website=San Diego Reader}}</ref> While he was at Disney, he developed a variety of patents for applying [[Xerography]] for  [[Xerography#Uses in animation|use in animation]].<ref>{{Cite web |title=USPTO Search Results for Iwerks and Xerographic. |url=https://ppubs.uspto.gov/pubwebapp/static/pages/ppubsbasic.html}}</ref>

== Personal life ==
Iwerks had two children with his wife, Mildred (née Henderson): [[Don Iwerks|Donald]] and David.  Donald went on to work for the Walt Disney company and to found [[SimEx-Iwerks|Iwerks Entertainment]]. His granddaughter is documentary film producer [[Leslie Iwerks]].<ref>{{cite web|url=https://www.youtube.com/watch?v=1fAv0NL2Ezc|title=Untold with Leslie Iwerks|publisher=[[Disney]]|via=[[YouTube]]|language=en-US|url-status=live|date=May 12, 2020|access-date=July 22, 2023|archive-date=July 22, 2023|archive-url=https://ghostarchive.org/varchive/1fAv0NL2Ezc}}</ref>  David Iwerks became a portrait photographer.<ref name="hollywood-studio-magazine-1966-11">{{Cite web |date=November 1966 |title=Dave Iwerks Catches Great in the Eye of His Perceptive Camera |url=https://archive.org/details/hollywood-studio-magazine-1966-11 |access-date=March 7, 2022 |website=Hollywood Studio Magazine |publisher=San Fernando Valley Pub.

== Influence and tributes ==
The ''Ub Iwerks Award for Technical Achievement'', as part of the [[Annie Award]]s, is named in his honour.

A rare self-portrait of Iwerks was found in a garbage bin at an animation studio in Burbank. The portrait was saved and is now part of the [[ASIFA-Hollywood Animation Archive Project|Animation Archives]] in Burbank, California.

After [[World War II]], much of Iwerks' early animation style was imitated by legendary [[manga]] artists [[Osamu Tezuka]] and [[Shotaro Ishinomori]].{{cn|date=April 2025}}

In 1989, Iwerks was named a [[Disney legend]].

In the 1996 ''[[The Simpsons]]'' episode "[[The Day the Violence Died]]", a relationship similar to Iwerks' early relationship with [[Walt Disney]] is used as the main plot.

A documentary film, ''The Hand Behind the Mouse: The Ub Iwerks Story'', was released in 1999, followed by a book written by Iwerks' granddaughter [[Leslie Iwerks]] and John Kenworthy in 2001. The documentary, created by Leslie Iwerks, was released as part of [[Walt Disney Treasures: Wave Seven|The Walt Disney Treasures, Wave VII series]] (disc two of The Adventures of Oswald the Lucky Rabbit collection).<ref>{{Cite web |title=The Hand Behind the Mouse: The Ub Iwerks Story (1999) |url=https://www.waltdisney.org/education/films/hand-behind-mouse-ub-iwerks-story-1999 |url-status=live |archive-url=https://web.archive.org/web/20220308083001/https://www.waltdisney.org/education/films/hand-behind-mouse-ub-iwerks-story-1999 |archive-date=March 8, 2022 |access-date=March 8, 2022 |website=[[The Walt Disney Family Museum]]}}</ref><ref>{{Cite web |title=The Hand Behind the Mouse: Stories of Ub with Don and Leslie Iwerks |url=https://www.waltdisney.org/education/talks/sold-out-hand-behind-mouse-stories-ub-don-and-leslie-iwerks |url-status=live |archive-url=https://web.archive.org/web/20220308082959/https://www.waltdisney.org/education/talks/sold-out-hand-behind-mouse-stories-ub-don-and-leslie-iwerks |archive-date=March 8, 2022 |access-date=March 8, 2022 |website=[[The Walt Disney Family Museum]]}}</ref>

A feature film released in 2014, ''[[Walt Before Mickey]]'', showed how Ub Iwerks, portrayed by [[Armando Gutierrez]], and Walt Disney, portrayed by [[Thomas Ian Nicholas]], co-created Mickey Mouse.

The sixth episode from the second season of ''[[Drunk History]]'' ("Hollywood") tells about Ub's work relationship with Disney, with stress on the creation of [[Mickey Mouse]]. Iwerks was portrayed in the episode by [[Tony Hale]].
