Boysen

Boysen is a surname of Scandinavian origin that has also been used as a place name and in the naming of a fruit variety. As a surname, it is found in Denmark, Norway, Germany, and the United States, among other countries.

Boysenberry is a hybrid fruit named after Rudolph Boysen, a California farmer who developed a cross between blackberry, raspberry, and loganberry in the early 20th century. The variety was later cultivated and popularized by Walter Knott of Knott's Berry Farm in California, helping to bring the berry to broader recognition.

Geographically, the name Boysen appears in Wyoming, where Boysen Dam on the Wind River created Boysen Reservoir, and the surrounding area includes Boysen State Park. The reservoir and park are notable local features used for recreation and wildlife habitat.

In summary, Boysen functions as a family name with Scandinavian roots and as a geographic and horticultural marker in North America, most prominently associated with the Boysenberry and with places in Wyoming.
