Learn about the name Theodore.With his mustache and spectacles, our 26th president, Theodore Roosevelt, was both rugged and refined — city boy meets country boy. He led the U.S. into a more active role in world politics, with his motto "Speak softly and carry a big stick." He was the inspiration behind the first teddy bear in 1903. We have a hunch that the names Theodore, Theo, and Teddy will soon be really big on baby name charts. Originally a Greek name, Theodore means "gift of God." Filmmaker Steven Spielberg has a son named Theo, and actresses Bryce Dallas Howard and Ali Larter have sons named Theodore.
