Ames Laboratory earns Historic Chemical Landmark designation

WASHINGTON, May 16, 2022 — The American Chemical Society (ACS) will honor the production of pure uranium metal at Ames Laboratory by designating the lab an ACS National Historic Chemical Landmark. The landmark status is in honor of the heroic effort by a dedicated group of scientists and technicians at a college in the middle of Iowa. Their little-known story is an integral and essential part of the Manhattan Project, which was a decisive factor in ending World War II.

The Landmark designation ceremony will take place at Ames Laboratory, Iowa State University, on May 17 at 11:45 a.m. CT. The ceremony will be part of the lab’s 75th anniversary celebration.

“With this landmark designation, we pay tribute to the vision, determination and sheer endurance of the scientists and other staff members who developed techniques to produce huge quantities of ultrapure uranium for the Manhattan Project,” says Lisa Balbes, Ph.D., member of the ACS Board of Directors. “This intensive mission advanced national security and contributed to the development of nuclear power.”

ACS established the National Historic Chemical Landmarks program in 1992 to recognize seminal events in the history of chemistry and to increase awareness of the contributions of chemistry to society. Past landmarks include the discovery and production of penicillin, the invention of synthetic plastics and the works of such notable scientific figures as educator George Washington Carver and environmentalist Rachel Carson.

The American Chemical Society (ACS) is a nonprofit organization chartered by the U.S. Congress. ACS’ mission is to advance the broader chemistry enterprise and its practitioners for the benefit of Earth and all its people. The Society is a global leader in promoting excellence in science education and providing access to chemistry-related information and research through its multiple research solutions, peer-reviewed journals, scientific conferences, eBooks and weekly news periodical Chemical & Engineering News. ACS journals are among the most cited, most trusted and most read within the scientific literature; however, ACS itself does not conduct chemical research. As a leader in scientific information solutions, its CAS division partners with global innovators to accelerate breakthroughs by curating, connecting and analyzing the world’s scientific knowledge. ACS’ main offices are in Washington, D.C., and Columbus, Ohio.
