This aerial view of Pennsylvania Salt Manufacturing Company shows their building complex, 2901 Taylor Way, as it appeared in July 1956. Storage tanks dot the area around the plant and one of the Pennwalt barges can be seen being maneuvered to the dock by two tugs. In 1928, the eastern firm was invited to build a caustic soda and liquid chlorine plant on 14 acres of filled ground adjacent to the Hylebos Waterway. The plant opened the following year as Tacoma ElectroChemical Company. As the parent firm diversified the plants' chemical production, it became known as Pennsalt, and then Pennwalt. Pennwalt Corp. was taken over by Elf-Atochem in 1990. ("South on the Sound" by Murray Morgan)
