The One and Only Ivan

Overview

Katherine Applegate’s The One and Only Ivan is a children’s novel first published in 2012, illustrated by Patricia Castelao. Often read as a middle-grade animal story, it is also a quietly serious work about captivity, friendship, art, memory, and the responsibilities people have toward other living creatures. The novel won the 2013 Newbery Medal and became a New York Times bestseller. Its accessible language and short, lyrical sections have helped it reach both young readers and adults.

Ivan is a silverback gorilla who has spent many years in an enclosure at the Big Top Mall and Video Arcade. He calls this glass-and-concrete space his domain. His routine includes eating, watching television, observing the people who stop to look at him, and making pictures that are sold in the mall’s gift shop. Ivan is patient and often funny, but his quiet acceptance of his surroundings does not mean he is free. His small circle of companions includes Stella, an older elephant; Bob, a stray dog who sleeps nearby; and Julia, the daughter of George, the mall custodian. Julia is an artist too, and her visits offer Ivan a kind of understanding that differs from the customers’ curiosity.

Story and themes

The arrival of Ruby, a young elephant, unsettles Ivan’s familiar routine. Ruby is frightened by her new surroundings, and her presence stirs Ivan’s hazy memories of an earlier life. Stella cares for Ruby and asks Ivan to promise that he will protect her. As Ivan watches Ruby struggle under the demands of the mall’s performances and training, he begins to see the enclosure differently. What has seemed like home is also a cage, and familiarity cannot make it a suitable place for an animal. Stella’s fate intensifies Ivan’s resolve. He uses his drawing to communicate Ruby’s situation to people outside the enclosure and tries to help her reach a place where she can live more freely. The plot is therefore not only about escape: it follows Ivan’s movement from patient accommodation toward responsibility and action on behalf of a friend.

Applegate tells the story in brief, poetic vignettes from Ivan’s first-person perspective. The form suits his observant voice, moving among small jokes, memories, impressions, and moments of stillness. Art is central to the novel: drawing gives Ivan a means of expression and a way to make his experience visible to human beings. The book asks how art can bridge differences between species, while also distinguishing genuine care from the human desire to display or control animals. Friendship and a promise give the narrative its emotional momentum; questions of animal welfare, freedom, home, and human accountability give it lasting weight. Ivan is portrayed as an individual with his own temperament and interests, not merely as a symbol, even as his story invites readers to consider the broader conditions of captive animals.

Background and legacy

The novel was inspired by a real silverback gorilla named Ivan. Captured in the Democratic Republic of Congo, the real Ivan spent about 27 years living at a mall in Washington state before moving to Zoo Atlanta in 1994. Applegate used that history as a starting point for fiction. Her Ivan understands human speech and narrates his own story; the book’s voice and plot are imaginative choices rather than a documentary account. By pairing the premise’s serious ethical questions with humor, tenderness, and an animal narrator, Applegate makes difficult subjects approachable without reducing them to a simple lesson.

The Newbery Medal established the book as a notable work of contemporary American children’s literature, and it has remained a popular choice for young readers, families, and classrooms. Its success helped bring a story about captivity and animal care to a wide audience through a personal, memorable character. A Disney film adaptation released in 2020 introduced Ivan to still more viewers, and the novel was followed by further books in the series. Its enduring place rests on the way it joins an intimate story of friendship and artistic expression to a larger invitation: to consider what freedom, home, and responsibility should mean for animals living under human care.

About the Author

Katherine Applegate

Early life and education

Katherine Applegate is an American author best known for books for young readers. She was born in 1956 in Ann Arbor, Michigan, and grew up in Grand Rapids. Animals were important to her from childhood: her family had pets, and while she was in high school she worked for a veterinarian. At about ten, she earned money by selling gerbils, an early entrepreneurial venture she has recalled with humor. She also ran a cleaning business and later spent several years doing ghostwriting. These experiences preceded a long career in children’s publishing rather than a straightforward path from school directly to authorship.

Applegate attended the University of Texas at Austin, where she studied in a liberal arts program. Around the time she was finishing college, she met Michael Grant, who became her husband and a frequent writing collaborator. The couple have two children and live in Nevada. Grant is also a children’s author, and their shared work has included books published under the K. A. Applegate name. Applegate’s public voice is often warm and self-deprecating; she has described writing as difficult work that is also deeply rewarding.

Career and major works

Applegate has written across a wide range of formats and reading levels, from chapter books to middle-grade and young adult fiction. One of her best-known early successes is the Animorphs science-fiction series, created with Michael Grant and launched in 1996. It follows young people who gain the ability to transform into animals and confront an alien threat. The series became a major children’s publishing phenomenon and established Applegate’s skill at building sustained narratives for young readers. She has also written under the name K. A. Applegate and other pen names, and her bibliography includes more than 150 books.

Her major later works include The One and Only Ivan (2012), which won the Newbery Medal in 2013; Crenshaw (2015), a novel about a child confronting family hardship; Wishtree (2017), which tells a story of community and inclusion through a tree’s perspective; Willodeen (2021); and Odder (2022). Her other work includes the Roscoe Riley Rules chapter-book series and the Endling series. Across these books, she moves between humor, adventure, fantasy, and realistic concerns, often giving animals or young people a distinctive point of view. The breadth of her output reflects both her productivity and her continuing interest in how children understand family, friendship, hardship, and responsibility.

Reputation

The One and Only Ivan is among Applegate’s most celebrated books. Inspired by a real gorilla’s life, it uses an imaginative animal narrator to address captivity, freedom, and human obligations without losing its humor or tenderness. The Newbery Medal and the book’s enduring popularity in homes and classrooms have helped secure Applegate’s standing in contemporary American children’s literature. A 2020 film adaptation brought the story to a wider audience. She remains a living, active author, and her reputation rests on an unusually broad body of work, an empathetic attention to animal lives, and a gift for making serious questions accessible to younger readers without talking down to them.
