One of his first jobs was at The Country Club as an assistant under Jack Hagen and he also worked at a course in Lake Placid, New York. In 1906 he moved to Des Moines, Iowa, where he was engaged as the professional and keeper of the greens at the Des Moines Golf and Country Club where he remained until 1916. He was a natural tinkerer and inventor. One of his first innovative ideas was a hitch for horses that allowed them to pull three gang mowers as a unit. His design was patented in the U.S., England, and France. Later he adapted a Ford Model T to serve as a tractor to pull the mowers.
He worked at a number of other locations, being engaged in Racine, Wisconsin, where he designed the Racine Country Club course. In 1917 he settled in Glenview, Illinois, near Chicago, where he designed courses and served as the first professional and course superintendent at the Westmoreland Country Club in Wilmette, Illinois. He left Westmoreland in 1928 to handle his golf course design business. In total, he is credited with the design of more than 50 golf courses and made alterations on at least 100 courses. He worked with Jack Burke, Sr. in the design of golf clubs and also collaborated with Burke in the operation of an indoor golf school in Des Moines around 1918.
Mower manufacturing
Roseman was one of the early pioneers in the use of comprehensive underground watering systems for golf courses. He sold this idea and the irrigation pipes along with his tractor mowers. In 1922, Roseman became the first president of the Illinois PGA. In the mid-1920s Roseman curtailed his career as golf professional to concentrate on manufacturing golf course equipment. He opened the Roseman Tractor Mowing Company in Evanston, Illinois, in 1928. Many of Roseman's roller-type mowers are still operational and being used at courses around the country.
In the 1920 PGA Championship, contested from August 17–21 at the Flossmoor Country Club outside Flossmoor, Illinois, a suburb south of Chicago, Roseman met Louis Tellier in a first round match. He was not playing his best golf and was soundly defeated in the match by the score of 10 and 9. Roseman took home $50 in prize money.
Family
Roseman and his wife had three sons – Joe, Jr., Warren, and Lewis – and one daughter, Mrs. James Hoffman.
Death and legacy
Roseman died on February 29, 1944 at his home in Glenview, Illinois. He is remembered as an inventor of golf course mowing equipment in the early 20th century and as an important golf course architect. He is known as the "father of the modern mower".
