Michael Langohr was a U.S. Forest Ranger and supervisor of Gallatin National Forest at the turn of the twentieth century. He was born in Adrian, Michigan on April 14, 1860 and came to Montana in 1898. He ran a grocery store in Bozeman, for a time, and began working for the forest service shortly thereafter. An avid gardener, Langohr began selling lettuce he grew in hot beds next to his house and expanded his business by building a greenhouse. He retired from his Forest Service job to run the nursery business full time in April, 1906. Michael Langohr died in Bozeman, Montana in 1935, but the business he founded continues in operation to the present.
