The National Organic Chemistry Symposium is the premier event sponsored by the ACS, Division of Organic Chemistry. The idea is to highlight recent advances in organic chemistry with a schedule that provides for open discussion of the science of organic chemistry. The history of NOS is documented here to the best of our abilities. Please send additions and corrections using the Contact Us Form found on the website.

The First National Symposium on Organic Chemistry was held in Rochester, N. Y., December 29 to 31, 1925, under the auspices of the Rochester Section and the Division of Organic Chemistry of the American Chemical Society.
