After briefly serving as professor of botany at the University of Chicago in 1868–70, Beal went on to Michigan Agricultural College (MAC, now
Michigan State University), where he was professor of botany (1871–1910) and curator of the botanical museum (1882–1905). During his tenure he also served as professor of horticulture (1872–1882) and professor of forestry (1882–1902). While at MAC, he arranged for
Liberty Hyde Bailey to work as an assistant to
Asa Gray at
Harvard University for two years during 1883–1884. He also served as co-director of the state Forestry Commission (1889–1892). Using his techniques, Beal was able to produce crops that bloomed earlier, were hardier, had more vigor, and had “better qualities” than traditionally grown varieties. He began conducting these experiments in 1878. He also conducted the first turfgrass experiments at the college in 1880. His successor at the Michigan Agricultural College, P.G. Holden, is quoted as praising Beal’s work by saying “From his original experiment has come to the Twentieth Century Miracle - hybrid corn.” Beal's work was inspired by many influential scientists of the late 19th century. He arrived at Harvard to complete an undergraduate degree 3 years after Charles Darwin published The Origin of Species. Emerson, Lowell, and Holmes were writing and lecturing, and Thoreau was still alive. Beal heard them all as a young student from Michigan. Groundbreaking research by Darwin and the writings of Emerson, Lowell, Holmes, and Thoreau were probably inspirations to a young Beal as he transitioned from studying at Harvard to conducting his research at the Michigan Agricultural College. Darwin’s research on inheritance especially seems to have influenced Beal’s development of hybrid corn. In 1887, he and Professor
Rolla C. Carpenter created "Collegeville", the first neighborhood in what later became
East Lansing. == Germination experiment ==
