Gary Felsenfeld, whose research at the National Institutes of Health revealed the dynamic nature of chromatin and its role in gene expression and epigenetic regulation, died on May 1, 2024, at the age of 94. Known for his wry sense of humor, dedicated mentorship and relentless pursuit of fun in the lab, Felsenfeld harnessed physical chemistry to measure protein–DNA interactions quantitatively and to define how nucleic acids form ordered structures.
