In memoriam: Margaret Fonda
Margaret Lee Fonda, a pioneer in biochemistry education and a member of the American Society for Biochemistry and Molecular Biology since 1972, died July 25 in Louisville, Kentucky. She was 82.
Born July 13, 1942, in Cleveland, Ohio, to Albert and Jean Loweth Fonda, she grew up in Alexandria, Virginia, and attended Salem College in North Carolina, then transferred to the University of Delaware where she received her BS in chemistry in 1965. At the University of Tennessee, she earned her Ph.D. in biochemistry in 1968.
Fonda pursued postdoctoral study at Iowa State University where she worked with biochemist David E. Metzler, studying interactions of pyridoxalphosphate analogs with aspartate aminotransferase, and also developed computer methods to generate the spectra of the enzyme-inhibitor and enzyme-substrate complexes and study various physiochemical parameters.
Fonda started her independent research career as a lecturer in the biochemistry department at the University of Louisville School of Medicine, Kentucky at the age of 28 in a department led and dominated by men. According to a news obituary, she was one of few women teaching at the time and was also younger than many of her students, who were mostly male.
In her lab, Fonda initially aimed to find activities of different decarboxylase and aminotransferase in mouse brains. Later, she extended her research to explore the effect of modifications of vitamin B6 phosphatase and pyridoxal phosphatase present in human erythrocytes. She published more than 39 papers in peer-reviewed journals and had over 965 citations.
In 1976, Fonda married George Herbener, a colleague at the medical school, and they retired together in 1995. The two volunteered for the Nature Conservancy and assisted the education department of the Louisville Zoo as docents for decades. Fonda loved to travel around the world and was a skilled photographer.
Fonda was preceded in death by her husband. She is survived by a sister, her five stepchildren and extended family.

Flipping lipids and slime molds
A dull first job nearly pushed JBC associate editor Todd Graham out of science. Then a slime mold project changed his path. Now, he studies membrane biology and reflects on discovery, persistence and mentoring through uncertainty.

ASBMB members receive RNA Society awards
The RNA Society awards Brenda Bass, Can Cenik and Karin Musier–Forsyth for their achievements in RNA research and innovation. Winners will be recognized at the closing awards ceremony of the RNA 2026 annual meeting.

In memoriam: Richard L. Cross
He studied the enzymatic mechanisms of ATP synthase and served on the editorial board of the Journal of Biological Chemistry for 24 years.

A chance encounter with the lab
Payton Stevens never planned to become a pancreatic cancer researcher. A temporary job set him on a path from rural Kentucky to leading research on Wnt signaling and metastasis, where he now pairs discovery with mentorship and science advocacy.

Piehl promoted to associate professor
He plans to develop a first-year chemistry lab program designed to help students build essential laboratory skills and connect core chemical concepts with real-world challenges.

In memoriam: Susan A. Henry
She was a pioneer in the study of yeast genetics and lipid metabolism and was an editorial board member of the Journal of Biological Chemistry.
