Alexander Chadbourne Eschweiler (August 10, 1865 – June 12, 1940) was an American architect with a practice in Milwaukee, Wisconsin. He designed both residences and commercial structures. His eye-catching Japonist pagoda design for filling stations for Wadham's Oil and Grease Company of Milwaukee were repeated over a hundred times, though only a very few survive. His substantial turn-of-the-20th-century residences for the Milwaukee business elite, in conservative Jacobethan or neo-Georgian idioms, have preserved their cachet in the city.
