Eight Lincoln High School students - five boys and three girls - stand in front of a chain link fence outside of the grounds of Manitowoc Shipbuilding Company in Manitowoc, Wisconsin in 1943. Most of the boys wear company identification buttons on their caps; one holds a lunch bucket under his arm. The students worked at the the shipyards after school. Manitowoc Shipbuilding Company built twenty-eight submarines for the U. S. Navy during World War II. Starting in September, 1940 with receipt of its first Navy contract, the company converted to a war production plant, and by March, 1941 its perimeter was guarded and fenced as shown here, with all employees required to show company identification to enter the gate. This picture was published in the 1943 Lincoln High School yearbook, "The Flambeau," under the caption "We Help Build Subs." The girls are Jean Schmidt, Jane Vnuk, and Marion Lenz. Behind them are Robert Johnson, Norbert Nelson, Donald Krejcarek, Emil Lakatos, and Robert Schmidt.
