The monument and surrounding lot are owned and maintained by the National Park Service, a federal agency of the Interior Department.

While serving on the faculty at Leipzig University, Hahnemann became disillusioned with standard medical procedures of the time, including over drugging and bleeding.

[4] A monument honoring Hahnemann was first proposed in 1881 by physician James H. McClelland at a meeting of the Homeopathic Medical Society.

Members of the nation's homeopathic community began raising funds, including the largest single donation of $4,510 by physician Nancy T.

The committee consisted of sculptors George Edwin Bissell, Daniel Chester French, and Olin Levi Warner, and architects Thomas Hastings and Russell Sturgis.

They were displayed at the American Academy of the Fine Arts in New York City, the first time a public exhibition of competition models was held in the country.

[4] Niehaus created Hahnemann's likeness by using a bust sculpted by David d'Angers that is now housed in the Saint Jacques Hospital in Paris.

Members such as Representative L. Irving Handy of Delaware argued that only individuals who had distinguished careers in the military or civil branches of the national government should be honored in the city.

[4] Hahnemann became the first foreigner not associated with the American Revolution to be honored with a sculpture in Washington, D.C.[4] The site selected for the monument was chosen by a committee created by Congress.

The committee included McClelland, who first proposed the monument, Senator George P. Wetmore and General John Moulder Wilson.

The committee chose a site on the east side of Scott Circle "by reason of its abundant opportunities to display to the best advantage the delicate lines which are features of the artist's work.

His remarks included: "This monument is erected in the hope that from it, as a center, truth may be spread which will result in the lessening of suffering and the increased usefulness of mankind."

The president of the AIH, physician Charles E. Walton of Cincinnati, then presented the monument to the government on behalf of the organization's members.

He said, "Their labors make it possible, in this memorable year 1900, which marks on the dial of time the dividing point of centuries, to rear in our nation's capital this beautiful monument commemorating at once the genius of Samuel Hahnemann and the loyalty of his followers."

An ode by physician William Tod Helmuth of New York was read followed by acceptance of the monument by government representative Colonel Theodore A. Bingham.

[8] On June 21, 2000, one hundred years after the original dedication, the AIH hosted "Homeopathy 2000: Rededication and Celebration in Washington, D.C." A rededication ceremony organized by homeopathic societies and other organizations was held with an Armed Forces Color Guard and music provided by the Marine Band Brass Quintet.

Working with the National Park Service (NPS), the committee hired conservator Judy Jacob to oversee the restoration.

The completion of the restoration project was marked by an event at the monument site on September 16, 2011, with representatives from the NPS and AIH in attendance.

Above Hahnemann on the niche is a decorative ceramic mosaic designed in the Art Nouveau style and keystone lion head.

The German inscription "DIE MILDE MACHT IST GROSS", meaning "Gentle Power is Great", is below the left reliefs.
