'''Rudolph Boysen''' (July_14, 1895 — November_25, 1950) was a Horticulturist who created the Boysenberry, a hybrid between several varieties of blackberries, raspberries, and loganberries. Unable to make his new berry a commercial success, he abandoned the effort. Walter_Knott was able to bring a few dying vines back to life and named the fruit after Boysen. The boysenberry has become popular worldwide. Boysen worked as Anaheim City Parks superintendent from 1921-1950. A 24-acre park in Anaheim was named in his honor, and features playgrounds, baseball diamonds, a large lawn, and a stucco-coated, Korean War-vintage Navy jet as a children's climbing toy. The Anaheim Tennis Center is located adjacent to Boysen Bark, which is at 951 S. State College Blvd. Rudolph Boysen died at the age of 55, and is interred at the Melrose Abbey Cemetery in Anaheim. {{US-scientist-stub}} {{botanist-stub}} Boysen, Rudolph Boysen, Rudolph Boysen, Rudolph
