About the author
Born in Brandon, Vermont, in 1860, Frank Hall Knowlton built a career around close observation of plants, birds, and fossils. He became especially known for paleobotany, the study of fossil plants, and was among the early American scientists to use plant evidence to better understand prehistoric environments.
Knowlton worked with the United States Geological Survey and also held roles connected with the United States National Museum. He taught at what is now George Washington University and published extensively on fossil floras, helping document ancient plant life in regions including the American West.
Beyond his technical research, he is remembered as a broad naturalist whose interests ranged across botany and ornithology. He died in 1926, leaving behind work that helped establish paleobotany as an important tool for studying Earth’s deep past.
