Wendelin Grimm moves to Carver County. Grimm begins experimenting with what he called Ewiger Klee, or "everlasting clover," in the next year, developing a winter-hardy strain of alfalfa. Fed to cows, this alfalfa would be critical to the dairy boom in the Upper Midwest. Local schoolteacher Arthur Lyman describes Grimm alfalfa in a speech to the State Agricultural Society on January 12, 1904; with this publicity it soon becomes a major American crop and the leading variety of alfalfa until the 1940s. A monument to Grimm was erected on his old farm in Laketown Township in 1924.
