The birth of the ALCA was not a sudden phenomenon. A group of leather chemists met at the annual convention of the Association of Official Agricultural Chemists (AOAC) in 1893. Their sole concern was to find an accurate method for analyzing the tanning extracts used in the industry. Extracts were often altered by traders or experimented with by tanners. Thus, commercial interests — and not purely scientific pursuits — sparked the initial banding together of leather chemists.
