Hahnemann monument

A bronze statue of Dr. Samuel Hahnemann set in a marble superstructure was built and dedicated in Washington D. C. by the American Institute of Homeopathy (AIH) with the help of President McKinley, a supporter of homeopathy and guest of honor at the ceremony, on June 21, 1900. The monument is located at the intersection of 16th Street and Massachusetts Avenue (Scott Circle) in Washington D.C., a location that can be seen from the White House. The sculptor was C. H. Niehaus and the architect was Julius. F. Harder.
The monument was rededicated June 21, 2000 on its 100th Anniversary at the Centennial Celebration of the AIH.
