Shirley Cotter was born in Minnesota in 1927 to Ralph and Myra Cotter.[2][3] Ralph Cotter was a plant pathologist at the University of Minnesota; growing up, Shirley Cotter would play in the university's greenhouses.[4]
Cotter maintained her interest in botany as an undergraduate student at the University of Minnesota; during this time, she collected over 4000 herbarium specimens. Her collection emphasized lichens. In 1951, Cotter became a graduate student in botany at University of California, Davis, studying under Katherine Esau.[2] During her graduate studies, Cotter met Kenneth Tucker. They married in 1953. Shirley Cotter Tucker earned her doctorate in botany in 1956.[5] Her dissertation was titled Ontogeny of the Inflorescence and the Flower in Drimys winteri var. chilensis.[2]
After graduating, Tucker had trouble finding permanent work at a university or college that would give her access to research funding. Instead, she sought external funding, receiving her first grant from the National Science Foundation in 1957. For 10 years, Tucker worked in temporary, non-tenure track university positions. She developed her work on lichens during this time, as a way around her lack of access to a laboratory.[4]
In 2014, Kenneth Tucker died. The next year Shirley Cotter Tucker made a gift to the Center for Plant Diversity which named the fund the "Shirley and Kenneth Tucker Fund" in their honor. Also in 2015 the herbarium was christened "The Shirley C. Tucker Herbarium".[2]
