Charles Rudolph Boysen (July 14, 1895 – November 25, 1950) was a California horticulturist. Boysen worked as Anaheim City Parks superintendent from 1921-1950. He created the boysenberry, a hybrid between several types of blackberries, raspberries, and loganberries.
Boysenberry[change | change source]
Rudolph Boysen experimented with various berry crosses in Napa, California in the 1920s. In 1923, his hybrid successfully grew and bore fruit. However, unable to make his new berry a commercial success, Boysen abandoned his crop after breaking his back in an accident.
Years later, after he had moved to Orange County, a fellow grower named Walter Knott heard about the berry and tracked down Boysen. Walter Knott was able to bring a few dying vines back to life at his farm, now known as Knott's Berry Farm in Buena Park, California. Knott named the fruit after Boysen.
