My students continue to process Luedtke Construction Co. folders. They are currently in the middle of the jobs folders, which include documentation of all the marine construction jobs the company completed from the 1940s through the 1990s. In the files of Job 577 , dredging and building a breakwater in Milwaukee from 1982 to 1984, there are some earlier photographs of similar work in Milwaukee done by tough men in wetsuits working for the S. M. Siesel Engineering Company. They look cold and brave. Cudos to Andrea for finding such cool photos.
