Lucretia Breazeale Hamilton (1908–1986) was an American botanical illustrator, who was considered an expert on southwestern United States flora.
[1] Hamilton, who had trained as a botanist, became an illustrator, because she was asked to provide drawings for some of her college professor's scientific articles, due to her detailed renderings.
[4] She was considered an expert in southwestern United States botanicals,[2] primarily due to her attention to detail and insistence that the plant be observed through all four seasons for an accurate depiction.
[1] In the 1950s, she illustrated a series of publications for the USDA Experiment Station of various plants with the intent of providing detailed images for ranchers to identify various types of grasses based on their nutritional value.
[1] Hamilton and her husband were founding members of the Tucson Native Plant Society[3] and she remained active in the organization until her death in June, 1986 in Pima, Arizona.
