"Minnesota became known as the `Gopher State' in 1857, the result of a political cartoon ridiculing the $5 million Railroad Loan which helped open up the West. The cartoon portrayed shifty railroad barons as striped gophers pulling a railroad car carrying the Territorial Legislature toward the "Slough of Despond". The first U of M yearbook bearing the name "Gopher Annual" appeared in 1887.
Minnesota's athletic teams became widely known as the "Gophers" by the 1920s but it was not until 1934 that the immortal Halsey Hall, great Minnesota sportswriter and broadcaster, dubbed Bernie Bierman's all-gold uniformed team "The Golden Gophers" (Bierman chose the gold color because the football blended in with the uniforms!).
The embodiment of the Gopher mascot came to life in 1952 when U of M assistant bandmaster Jerome Glass bought a fuzzy wool gopher suit with a papier mache head and asked one of the band members to climb into it. "Goldy" Gopher (the first name seems to have appeared sometime in the '60s) became a fixture with the Marching Band and Pep Band, as each year a bandmember was chosen to don the suit for that season. Wherever these two bands performed, Goldy was there to glad-hand with the crowd, hug the little kids, torment the cheerleaders and generally add a friendly Minnesota flavor to the event."
