National Chemical Historical Landmarks in Cincinnati Overview logo

The ACS National Chemical Historical Landmarks program honors chemical discoveries, innovations as well as chemists that transformed lives and our understanding of chemistry. The program, established in 1992, features more than 90 landmarks related to major chemical inventions and chemists. These landmarks honor scientists like Joseph Priestley, the discoverer of oxygen, inventions like Bakelite, the world’s first synthetic plastic, and the legacy of Rachel Carson’s Silent Spring. Cincinnati features two National Chemical Historical Landmarks.


The Development of Tide Synthetic Detergent logo

This landmark was dedicated in October 2006. Procter and Gamble first released Tide in 1946. Tide was not only a new product but a type of laundry detergent featuring not only the technology of fully synthetic detergents but also synthetic builders, compounds which enable cleaning performance in hard water.

An audience of 100 people attended the dedication ceremony. The curator of the museum, Professor Emeritus William Jensen gave a talk describing the life of UC Professor Ralph Oesper who not only started the collection of rare books and journals but also left endowments supporting scholarships in chemistry.
