The
Buick Motor Company was founded in 1903 by David Dunbar Buick, a Scottish-American inventor who invented the overhead valve engine. Buick sold his share in the company and quit and General Motors founder William C. Durant succeeded him.
Early Buick logos were variations of the cursive word "Buick." In 1930s, General Motor Styling researcher Ralph Pew found a description of the Scottish "Buik" family crest and decided to use it as a radiator grille decoration. In 1960, the logo incorporated three such shields, to represent the three Buick models then built: LeSabre, Invicta, and Electra.
In 1975, Buick changed their logo to a hawk named "Happy" with the launch of their Skyhawk line. However, in the late 1980s, as the Skyhawk car was retired, Buick went back to the tri-shield logo.
