Haupt v. United States 330 U.S. 1 (1947)
HAUPT v. UNITED STATES 330 U.S. 1 (1947)
Herbert Haupt, a German American, infiltrated into the United States during world war ii from a German submarine as part of a Nazi plot to sabotage American war industry. His father, Hans Max Haupt, allowed him to stay at the latter's home, bought a car for him, and helped him to get a job in a factory where Norden bomb sights were manufactured. There were at least two witnesses to each of these three acts, and on the basis of that testimony Hans Haupt was convicted of treason.
The Supreme Court sustained Haupt's conviction in an 8–1 decision. In an opinion by Justice robert h. jackson, the Court held that the overt acts testified to met the test laid down in cramer v. united states (1945): each constituted the actual giving of aid and comfort to an enemy spy. Unlike Anthony Cramer's public meetings with the saboteurs, Hans Haupt's "harboring and sheltering" of his son were of direct support to the enemy mission.
