About the author

Founded in 1884 as the Association of Official Agricultural Chemists, the organization began with a practical mission: creating uniform methods for analyzing fertilizers. Early support came through the U.S. Department of Agriculture, and the group soon became an important meeting place for government and laboratory chemists working on public standards.

Over time, its scope expanded beyond agricultural chemistry. Later known as AOAC and then AOAC INTERNATIONAL, it became closely associated with the development, testing, and validation of analytical methods used in food, agriculture, and related public health work. Its long-running publications and official methods helped give laboratories a shared scientific baseline.

Today, AOAC INTERNATIONAL describes itself as an independent, non-profit association serving professionals across government, industry, and academia. That long history makes the original Association of Official Agricultural Chemists less a single "author" in the usual sense and more a collective scientific voice behind trusted methods and reference works.
