Alden Springer Crafts (25 June 1897, Fort Collins, Colorado – 9 February 1990, Davis, California) was an American professor of botany, known as the first person in the United States to have the title "Weed Control Scientist" in academic employment.
After completing one year of academic study, he left college to work as an agricultural laborer at the Kearney field station.
and in 1930 with Ph.D. Wilfred William Robbins (1884–1952), who was on Crafts's thesis committee, offered him an academic position in weed control at UC Davis.
However, Crafts declined the offer because he had accepted a National Research Council fellowship at Cornell University.
At Cornell, Crafts was also influenced by Walter C. Muenscher (1891–1963), a botanist noted for his expertise on weeds.
