Biography
Jacob Wipf, a Hutterite from the Rockport Colony in South Dakota and brother-in-law of the Hofers, was the fourth of the Hutterite absolutists court-martialed in 1918 and sentenced to twenty years hard labor. Tortured at Alcatraz and imprisoned at Fort Leavenworth, he outlived the two Hofer brothers who died there and was released in the spring of 1919. The four men's ordeal spurred a wave of Hutterite emigration to Canada.
