Niels Ebbesen Hansen

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

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, where he was awarded his Master of Science degree in 1895.

In 1895,South Dakota State College (now South Dakota State University), appointed Hansen to build its Horticultural Department. 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.

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."
