Recruiting "Friends of Medical Progress": Evolving Tactics in the Defense of Animal Experimentation, 1910s and 1920s.

In 1923, Thomas Barbour of Harvard announced the creation of a national lay organization, the Society of Friends of Medical Progress (FMP), to defend animal research in the United States against a resurgent antivivisection movement. After decades of successful behind-the-scenes lobbying and avoiding the public spotlight, medical scientists significantly altered their tactics and sought public engagement, at least by proxy. Although the authority of scientific medicine was rising, women's suffrage, the advent of the ballot initiative, and a growing alliance of antivivisectionists and other groups in opposition to allopathic medicine so altered the political landscape that medical scientists reconsidered formerly rejected ideas such partnering with laymen. Medical scientists, Walter B. Cannon and Simon Flexner chief among them, hoped that the FMP would relieve the scientists of a time-consuming burden and defend against government regulation of medical institutions without the charge of material self-interest. However, financial problems and the frequent conflicts that arose between the lay leadership and Flexner eventually undermined the FMP's value as a defender of animal experimentation and reveal the distrust of reformers like Flexner who did not believe that laymen could speak for scientific medicine.
