Mary Agnes Chase: Pioneering Scientist and Suffragist

Mary Agnes Chase made history as a world-class expert on grasses, even though she formally ended her education in elementary school. This American botanist not only revolutionized the study of grasses across the Americas, but also risked her professional career by advocating for women’s suffrage.

Family Tragedy

Mary Agnes’ childhood was marked by a tragedy that forever changed her family’s fate. Born in 1869 in rural Illinois, she had to move with her mother and siblings to Chicago after her father’s death.

The family changed their last name, trying to start a new life far from memories of the past. In the big city, Mary Agnes was raised by her mother and grandmother, who strove to provide stability despite financial difficulties.

Mary Agnes’ formal education ended at the elementary level, which was not unusual for girls from working-class families at that time. However, a lack of diplomas did not stop her curiosity about the world. In 1888, at only nineteen, she married William Inghram Chase, a descendant of a respected American family. The marriage tragically lasted only a year; William died, leaving the young widow on her own.

As a widow, Chase worked as a proofreader at the Inter-Ocean newspaper while attending evening botany courses at the University of Chicago. These classes awakened her passion, which would define her life. Her talent for detailed drawing quickly caught the attention of local scientists, and botanist E.J. Hill hired her as an illustrator for his publications. Chase’s drawings were so precise and artistic that Charles Frederick Millspaugh of the Field Museum of Natural History soon became interested in her work.

A Collaboration That Changed American Botany

In 1903, a new chapter began in Chase’s career when she became an illustrator for the Department of Agriculture’s Agrostology Division in Washington, D.C. She initially illustrated forage plants, producing anatomical drawings of various grass species.

The true breakthrough came two years later, when she began working with Albert Spear Hitchcock, an esteemed specialist in grass systematics. Hitchcock quickly realized that Chase was much more than a talented illustrator.

The relationship between Hitchcock and Chase evolved from a typical supervisor-subordinate arrangement into a partnership of two equal scientists. Hitchcock stopped treating her as a student and began to recognize her as a full-fledged research collaborator. Together, they published two fundamental works on North American Panicum species in 1910 and 1915. In 1917, their next co-authored publication, Grasses of the West Indies, appeared, largely based on material Chase collected on a research expedition to Puerto Rico.

Despite growing recognition in the scientific community, Chase still faced barriers solely because of her gender. In 1911, after Hitchcock returned from a Smithsonian Institution-funded expedition to the Panama Canal Zone, he requested the remaining $54 from the grant to fund Chase’s fieldwork. A Smithsonian official refused, bluntly questioning the appropriateness of involving a woman in such work. This refusal perfectly illustrated the atmosphere women scientists faced in the early 20th century.

At the White House Gates

Her experiences with professional discrimination pushed Chase toward the suffragist movement, although she was keenly aware of the risks that public political activism could pose to her scientific career. She joined the Silent Sentinels, a group of activists connected to the National Woman’s Party, who staged spectacular protests outside the White House.

These women stood daily at the gates of the presidential residence with banners asking Woodrow Wilson how long American women would have to wait for freedom.

The demonstrations took many forms, from picketing every White House entrance to unveiling Women’s Votes banners during House of Representatives debates. Organizers presented themed days, during which women representing states or professions such as law, science, or journalism protested together.

Chase publicly announced that she would burn every publication by President Wilson containing the words „freedom” or „liberty” until women received the right to vote. Her colleagues in the scientific community did not always look favorably on such actions.

The authorities responded to the protests with mass arrests. Chase was imprisoned with other activists, including movement leader Alice Paul. The imprisoned women went on hunger strike, which guards answered with force-feeding. News of this brutal treatment reached the public, increasing sympathy for the suffragists. Social support eventually forced the release of the arrested women and accelerated the ratification of the Nineteenth Amendment granting women the right to vote.

An Impressive Legacy

With suffrage achieved, Chase could fully focus on her scientific work, bringing her international recognition. Research expeditions took her to Brazil, Venezuela, and other parts of South America, from where she brought thousands of grass specimens to American scientific collections.

She also conducted fieldwork in Europe, systematically expanding knowledge of the world’s grass flora. Her textbook, First Book of Grasses, which explained grass structure in accessible language, was translated into Spanish and Portuguese.

Chase ultimately became a senior botanist, taking charge of the entire Systematic Agrostology Division in the Department of Agriculture. A woman without formal higher education led one of the most important research institutions in her field. For over three decades, she shaped American grass studies, and her illustrations and species descriptions remain reference points for specialists to this day. She also opened doors for future generations by hosting young women researchers in her home and supporting their scientific development.

The scientific community eventually honored her contributions with numerous awards. In 1956, the Botanical Society of America gave her a Certificate of Merit, and the University of Illinois awarded her an honorary doctorate. She also became a member of the Linnean Society of London, one of the world’s oldest scientific societies. Mary Agnes Chase died in 1963, leaving not only an impressive scholarly legacy behind, but also an inspiring story of a woman who refused to accept society’s limits.
