Anna Pedersen Kummer

Kummer was a local botanist and teacher, associated with the University of Chicago and Waller High School in Chicago. She studied native plant species that most people identified as “weeds” but was a proponent for recognizing these native plants’ value in local habitats. She published numerous articles in journals for colleagues and the general public. In 1938, she created an exhibit featured at the Chicago Academy of Sciences’ museum that focused on common weeds of the area, composed of her own specimens. This attracted considerable attention at the Academy, and a year later, she furnished another exhibit, this one much larger, comprised of about 50 species from the Academy’s botanical collection, which she collected locally and in other locales around the Midwest. Kummer served as Honorary Curator of Botany for the Academy through the 1940s, during which time she managed the herbarium and added many of the plant specimens she collected from across Illinois and Indiana.

In 1942, she created her largest exhibit yet in the Laflin building, featuring 192 common weeds found in the Chicago area. Her work on weeds in the Chicago Naturalist demonstrated that the short-grass regions of our Midwest and west were vital plant species. She is quoted in the article, “While the weed cover seems a deterrent to successful reoccupation of the short grass, it is actually necessary to that process.” And again, “Without them [weeds] the short grass could not have survived as climax vegetation.” Kummer is credited with illuminating the vital role these plants play in ecosystems and their ability to pave the way for the return of short grass. As guardians of the soil, and a powerful player in the complex world of plant weeds, Kummer’s observation rings true — “weeds are not all without beauty”.
