Bob Peterson Bio

Robert Peterson (born January 18, 1961) is an American cartoonist, animator, director, screenwriter, storyboard supervisor, and voice actor who has spent the bulk of his professional life at Pixar Animation Studios. Over a career that began in the late 1970s, he has helped shape some of the most enduring animated films and shorts of the modern era, from the studio’s earliest feature work to its more recent streaming series. He is best known for his creative partnership on Up, his screenwriting contributions to Finding Nemo, and for voicing several beloved Pixar characters, including Dug, Roz, and Mr. Ray. His work has earned nominations for the Academy Award for Best Original Screenplay as well as a Primetime Emmy Award.

Early Life and Background

Robert Peterson was born on January 18, 1961, in Wooster, Ohio, in the United States. He grew up in the Midwest, the region whose landscapes and rhythms would later inform the visual texture of several Pixar productions. As a young man, Peterson demonstrated an unusual combination of talents, excelling in the technical fields while also nurturing a strong passion for drawing and humor.

He pursued higher education at Ohio Northern University, where he earned a Bachelor of Science in Mechanical Engineering in 1983. During those undergraduate years, he began his artistic career by drawing a weekly campus cartoon titled For Pete’s Sake, marking his earliest published work as a cartoonist. He then continued his studies at Purdue University, completing a Master of Science degree in Mechanical Engineering in 1986. While at Purdue, he drew a regular cartoon called Loco Motives for the Purdue Exponent student newspaper, and in the months before his December 1986 graduation, the Exponent published a paperback compilation of his cartoons titled Loco Motives: Boilercoaster 84-86. He autographed copies at a book-signing event held in the Purdue Memorial Union in October 1986.

Path to Animation

Even as he trained as an engineer, Peterson continued developing his voice as a cartoonist and visual storyteller. The campus newspaper work and the published compilation demonstrated a level of skill and consistency that would later open doors in the animation industry. He was not trained formally as an animator during these years; instead, his path into film came through his self-taught illustration and a willingness to apply his technical background in a creative field.

His transition into animation came in 1994, when he was hired at Pixar by Roger Gould as an animator working on commercials. That short-form work gave him a foothold inside the studio, and he soon moved onto feature projects. By 1995, he was part of the animation team on Toy Story, Pixar’s groundbreaking first feature, which positioned him at the center of a new era in computer-animated storytelling.

Bob Peterson Career

Early Career (1994–2003)

Peterson’s earliest years at Pixar centered on animation and the development of distinctive character voices. In 1997, he voiced the elderly title character in the short film Geri’s Game, which won the Academy Award for Best Animated Short Film and helped establish the studio’s reputation for character-driven shorts. He went on to voice Roz, the slithering, sludgy administrator, in Monsters, Inc. (2001), giving the character a memorable deadpan that became a fan favorite.

In 2003, he co-wrote the screenplay for Finding Nemo, contributing to one of Pixar’s most celebrated features. The film earned him his first Academy Award nomination, this time for Best Original Screenplay. He also voiced Mr. Ray, the friendly schoolteacher shark, in Finding Nemo, adding another signature character to his vocal repertoire.

Breakthrough (2009–2013)

Peterson’s most prominent period arrived with Up (2009), the Pixar feature about an aging widower, a young scout, and a floating house bound for South America. On Up, he served as co-director, co-head of story, co-writer, and voice actor, working alongside director Pete Docter. The film earned widespread critical praise and won the Academy Award for Best Animated Feature and Best Original Score. Peterson personally received an Academy Award nomination for Best Original Screenplay, recognizing his central role in shaping the film’s story and emotional structure. He also voiced both Dug, the lovable golden retriever with a translated collar, and Alpha, the intimidating leader of the dog pack, performances that have become enduring parts of his legacy.

During this period, he also conceived the idea for The Good Dinosaur (2015), an original story about a young dinosaur and a human boy. He was originally attached to direct the film before exiting the project in August 2013. He also continued his voice work, reprising the role of Mr. Ray in Finding Dory (2016) and returning as Roz in Monsters University (2013), extending two of his most recognizable characters into new stories.

Notable Works and Milestones

Beyond his feature work, Peterson created, wrote, and directed two short-form streaming series that expanded Pixar’s presence on Disney+. Forky Asks a Question (2019–20) was a series of shorts centered on the spork-based character from Toy Story 4, while Dug Days (2021–23) followed the continuing adventures of the dog from Up. Forky Asks a Question earned Peterson his first Primetime Emmy Award, in the Outstanding Short Form Animated Program category, in 2020. He also co-wrote Cars 3 (2017), voicing the character Chick Hicks, who had previously been voiced by Michael Keaton.
