Mickey Mouse was almost named Mortimer
After losing Oswald the Lucky Rabbit, Walt Disney and Ub Iwerks needed a new star in 1928. Walt favored Mortimer Mouse until Lillian Disney suggested Mickey. Two silent trials failed to find distributors; synchronized-sound Steamboat Willie made the mouse a public sensation.
Mickey Mouse, co-created in 1928 by Disney and Iwerks, remains the Walt Disney Company's longtime mascot—an anthropomorphic mouse in red shorts, oversized shoes, and white gloves, usually joined by Minnie, Pluto, Donald, and Goofy. He replaced Oswald after rights troubles, debuted quietly in Plane Crazy and The Gallopin' Gaucho, then broke through with Steamboat Willie the same year. Inspired by Chaplin and Fairbanks, he plays a plucky underdog whose small stature and falsetto—originally Walt's own voice—signal vulnerability met with ingenuity. Ten cartoons earned Academy Award nominations for Best Animated Short; parks still stage meet-and-greets with the global icon of twentieth-century animation.
The character evolved from mischievous early shorts toward a sweeter corporate emblem as the studio grew. Merchandising, video games, and endless cameos locked the circular ears and buttoned shorts into advertising history. What began as an emergency substitute for a lost rabbit became the face of an entertainment empire—and a shorthand for American cartoon modernity worldwide. Critics and marketers alike treat him as one of the most recognizable fictional figures ever drawn.
Naming lore matters because it shows how contingent icons are: one spouse's preference swapped Mortimer for Mickey, and one sound cartoon outran two silent experiments that distributors ignored. The gloves and buttons look inevitable now; in 1928 they were improvisations on a deadline after Oswald slipped away. From a rejected rabbit to a park handshake, Mickey's arc is the studio's origin myth in mouse form.
