Who designed the eagle going through the A on the Anheuser Busch emblem?

The A and Eagle trademark is the most widely recognized symbol of Anheuser-Busch Companies, Inc. and Anheuser-Busch, Inc. First used on the company's beer products in 1872, the symbol was not registered with U.S. Patent Office until 1877. The trademark (No. 4623) soon became widely recognized as a symbol of quality throughout the world.
