George Caldwell served as president of the American Chemical Society (ACS) in 1892. Prior to this time, the ACS had been a rather parochial New York City based organization. In 1890, the constituency of the ACS expressed its desire to become a truly national body. Toward this end, it forged closer ties with the Chemical Section of the American Association for the Advancement of Science (AAAS), and merged with the Chemical Section in 1891. As Caldwell had been active with the AAAS group for several years previous to this merger, his election to the presidency of the ACS can be seen as an expression of unity in the American chemical community.


This paper was originally presented as an invited paper for the “Cachet Series on Past Presidents” at the 1991 meeting of the American Chemical Society in Atlanta, Georgia. It has been revised and expanded since that time. The author thanks Scott Juskiewicz, Kristi Carroll, and other Montana Tech Library administrators and staff for helping make this research and publication possible.
