Many people seeking relief from ragweed and other fall allergens can thank a University of Cincinnati professor when they reach for their box of Benadryl.
The late George Rieveschl invented the blockbuster bestselling antihistamine which has helped countless millions of people with allergies, itchy rashes and cold symptoms.

The American Chemical Society this week honored Rieveschl's profound contributions to society with a new National Historic Chemical Landmark dedicated to his discovery. The discovery joins an esteemed list of 100 other scientific achievements, from Scotch tape to the first synthetic laundry detergent, Tide, since the award was established in 1992.
"This recognition celebrates the legacy of Benadryl, George Rieveschl and the University of Cincinnati and the enduring impact of chemistry on our lives," UC alumna and American Chemical Society President Dorothy Phillips said.
Phillips is a trailblazing chemist and the first African American woman to earn a doctoral degree in biochemistry at UC. She was joined by past American Chemical Society presidents Silvia Jurisson and Diane Schmidt, both UC alumni.
"Progress takes time, it takes vision and it takes people who are willing to see possibilities, even when the outcome is uncertain," Phillips said. "That's what we celebrate today, a legacy built with purpose and care and I'm honored to be a part of it."

UC unveiled the society's plaque while celebrating the Department of Chemistry's 150th anniversary and the newly renovated Old Chemistry building.
"For 150 years, chemistry at UC has advanced knowledge, trained innovators and improved lives," UC Interim Provost John Weidner said. "I have no doubt that the next 150 years will bring discoveries we have yet to imagine."
Weidner, a chemical engineer, lauded Rieveschl's groundbreaking discovery.
"George's story shows us what can happen when curiosity, talent and collaboration meet. We believe Old Chem's new chapter will inspire the same spirit of innovation for generations to come," Weidner said.
Dr. Rieveschl's legacy extends far beyond one antihistamine. He helped transform UC into the research powerhouse it is today.

The award marks the second such honor for UC. In 2022, the society recognized UC's Oesper Collections in the History of Chemistry, one of the world's largest stores of scientific artifacts, chemistry books and papers, many of which are on display in a campus museum.
"Dr. Rieveschl's legacy extends far beyond one antihistamine," UC Vice President for Research Patrick Limbach said. "He helped transform UC into the research powerhouse it is today through his science, his leadership and his philanthropy. It was a sincere honor and pleasure to know him personally and benefit from his generous spirit and zest for discovery."
Today produced by Johnson & Johnson and Pfizer, Benadryl was the first FDA-approved prescription antihistamine in 1946. It became a popular over-the-counter drug in 1982.

After earning bachelor's, master's and doctoral degrees at UC, Rieveschl worked as an industry scientist for 26 years before returning to UC in 1970 to teach chemical engineering in UC's College of Engineering and Applied Science.
Rieveschl was inducted into the International Science and Engineering Hall of Fame in 1995. He died in 2007 at age 91.
"Millions of sufferers of allergies, colds, rashes, hives and hayfever can thank George Rieveschl for the relief they receive by swallowing a capsule of the antihistamine he invented and renamed Benadryl," the New York Times wrote in his news obituary.
UC recognizes distinguished scientific research among faculty each year with an award given in Rieveschl's honor. He is also the namesake of Rieveschl Hall on UC's Uptown Campus.
His papers are maintained at Cincinnati's Lloyd Library.

The problem with lead is that it's so hard to detect. The heavy metal is found in everything from paints and ammunition to car batteries and antique toys. Malleable, cheap and abundant, lead was a favorite material for pipes and plumbing fittings dating back to the Roman Empire. But it's also toxic, so toxic that exposure can cause lifelong cognitive and neurological impairments in children.
