GERMAN AMERICAN INS CO
Now known as the Great American Life Insurance Company (GALIC), the German American Insurance Company was founded in 1872. The company changed its name to the Great American Insurance Company in 1918, when World War I created a wave of anti-German feeling in the United States. The company clearly decided to overcompensate when it chose the "Great American" moniker.
