Mary Agnes Chase was granted U.S. Patent 2,609,322 for "Production of Penicillin Mold and Jelly," reflecting work beyond botanical taxonomy.
On 8 July 1962, Mary Agnes Chase was granted U.S. Patent No. 2,609,322 for an invention titled "Production of Penicillin Mold and Jelly".[17] Although best known as a botanist and agrostologist, Chase’s name appears on this patent, reflecting her participation in applied research beyond classical plant taxonomy.
The patent relates to methods for producing penicillin mold and a jelly medium, part of broader mid-twentieth-century efforts to improve antibiotic production techniques.[17] Coming nearly two decades after penicillin’s initial deployment in World War II, such work aimed to refine culture conditions, increase yields, and facilitate laboratory and industrial use. Chase’s involvement indicates her willingness to engage with microbiological and biochemical problems adjacent to her botanical expertise.
Historically, the patent is notable as an unusual extension of a botanist’s career into biomedical innovation. Few women of her generation held patents, and even fewer combined long-term herbarium work with contributions to antibiotic production.[2] The 8 July 1962 grant therefore adds a distinctive dimension to her legacy, showing that her scientific curiosity and collaborative work crossed disciplinary boundaries and participated in the era’s transformative developments in medicine.
