Niels Ebbesen Hansen (January 4, 1866 – October 5, 1950) was a Danish-American horticulturist and botanist who was a pioneer in plant breeding.

Background[edit]

Niels Ebbesen Hansen was born in the village of Fardrup, in Ribe County, Denmark. He was the son of Danish-born muralist Andreas Hansen and Bodil Midtgaard. His parents brought him to the United States at the age of seven. In 1876, the family moved to Des Moines, Iowa. At the age of seventeen he entered Iowa State College from which he graduated with a B.S. in horticulture in 1887. After graduation, he worked for a time in a large grape nursery. He was induced to return to Iowa State. He was awarded his Master of Science degree in 1895.[1]

Career[edit]

South Dakota State College (now South Dakota State University), then looking for someone to build its Horticultural Department, selected Hansen for the job. In 1895, Hansen came to South Dakota and became head of the Horticultural Department of South Dakota State College.[2][3] He also served as the director of the South Dakota Experiment Station at Brookings.

Hansen searched for new grasses, fruits and other plants throughout Europe and Asia. He brought these plants back to America to raise or crossbreed with American varieties to produce a stronger plant. He was the originator of many new fruits, among them the Hansen hybrid plums. He is credited with the discovery and introduction of hardy Cossack alfalfa, crested wheat grass and brome grass. He developed larger apricots and plums by crossing native varieties with those he brought from Asia.[4]

On an 1897 trip to Russia, he encountered the red-fleshed wild apple Malus niedzwetskyana and began two breeding programs based on this unusual fruit, one aimed at developing a cold-hardy cooking and eating apple, and the other aimed at developing ornamental crabapples. His efforts resulted in the Almata apple and the Hopa crabapple, among other varieties. When he discovered that the northwest apple breeder Albert Etter had beaten him to the punch in creating red-fleshed hybrids, he wrote to concede him priority with the words "Mr. Etter, you have defeated me in my destiny." [5]

Hansen was a member of the International Jury of Horticulture at the World's Fair in St. Louis, Missouri in 1904 and a United States delegate to the First International Congress of Genetics in London, England in 1906. He served as secretary of the South Dakota Horticultural Society for many years. In 1949, a monument in recognition of Dr. Hansen and his contributions was erected on the campus of South Dakota State College.[6][7][8]

A collection of the records, faculty papers, and related materials of Niels Ebbesen Hansen are maintained in the Archives of South Dakota State University.[9]
