MGM Lion

In 1924, studio publicist Howard Dietz designed the "Leo The Lion" logo for Samuel Goldwyn's Goldwyn Picture Corporation. He based it on the athletic team of his alma mater Columbia University, the Lions. When Goldwyn Pictures merged with Metro Pictures Corporation and Louis B. Mayer Pictures, the newly formed MGM retained the logo.

Since then, there have been five lions playing the role of "Leo The Lion". The first was Slats, who graced the openings of MGM's silent films from 1924 to 1928. The next lion, Jackie, was the first MGM lion whose roar was heard by the audience. Though the movies were silent, Jackie's famous growl-roar-growl sequence was played over the phonograph as the logo appeared on screen. He was also the first lion to appear in Technicolor in 1932.

The third lion and probably most famous was Tanner (though at the time Jackie was still used concurrently for MGM's black and white films). After a brief use of an unnamed (and very mane-y) fourth lion, MGM settled on Leo, which the studio has used since 1957.
