Edwin Blake Payson

[4] He trained at Camp Funston, then returned to Laramie for his marriage to Louise Butler, a fellow botany student.

[5] After the end of World War I, Payson was an instructor at the American Expeditionary Forces University at Beaune, France.

Unfortunately he suffered a partial paralysis of his left arm in 1926, underwent gall bladder surgery in 1927, and died shortly afterwards of heart failure.

[7] Shortly before his death Payson was awarded a Guggenheim Fellowship to "continue evolutionary and taxonomic studies of flowering plants of the families Cruciferae and Ranunculaceae with special emphasis on the question of generic phylogenies; the genera Draba and Aquilegia are to be studied in detail, mainly at Kew Gardens, London".

[10] Payson married Louise "Lois" Elizabeth Butler (1895–1970), a botanist, librarian, and plant collector.
