ACS National Historic Chemical Landmarks

Contributor II

ACS established the National Historic Chemical Landmarks program in 1992 to enhance public appreciation for the contributions of the chemical sciences to modern life in the United States and to encourage a sense of pride in their practitioners. To date, the program has recognized 70 subjects in the United States and around the world.

ACS local sections, divisions or committees can nominate subjects for the program. To qualify, subjects must clearly represent seminal achievements in the history of chemistry; they must evidence significant impact and benefit to the public and the chemistry profession; and they must be at least 25 years old. ACS recognizes approximately three new Landmarks annually.

Recent achievements recognized through this program have included the development of fluorescent pigments, the legacy of Rachel Carson’s Silent Spring, and the Mellon Institute of Industrial Research.
