Born in Portland, Maine, on July 22, 1910, Tompson was raised in Boston, Massachusetts, before she and her family relocated to California years later in 1918. According to Disney's statement, Tompson obtained a job at one point at Dubrock's Riding Academy, where Walt Disney and his brother Roy would play polo.

After getting to know one another, Walt eventually offered Tompson a job as a painter in The Walt Disney Company's Ink & Paint Department, where she put final touches onSnow White and the Seven Dwarfs — the studio's first full-length animated film. "We worked into the night, day after day, until we got it exactly right," Tompson previously said of the project.

Tompson was later promoted to final checker for the company, where she would review animation cels before they were photographed onto film, before she was transferred to animation checking and scene planning. Tompson's skills behind the scenes prompted her to be invited to join the International Photographers Union, Local 659 of the IATSE, Disney said.

The skilled animator would later retire from The Walt Disney Company after she worked on just about every animated feature for the company up throughThe Rescuers. Though she would go on to work for other studios for another ten years, Tompson once said, "It is always my Disney experience that is filled with truly unforgettable memories."
