Pennsylvania Salt Manufacturing Co. of Washington had long been established in Tacoma; it was to celebrate its 25th anniversary locally in 1954. It started with a 40 acre tract of land on the Hylebos Waterway and has steadily expanded, adding new buildings and machinery, to fill the needs of the pulp and paper industry.

Pennsylvania Salt Manufacturing Co. Family Day; employees' picnic and open house. An unidentified group of employees stands in front of a display case set up for the open house. Wives, husbands and children of employees were invited on this day to tour the plant. A brief program was devoted to safety measures practiced at the plant. Lunch for 300 employees and their visitors was followed by a tour of the plant. The manufacturing facility opened on the Tideflats in June of 1929 as Tacoma Electro-Chemical Co. Despite its deceptive name, Pennsalt manufactured industrial chemicals, some of which were used in the manufacture of pulp and paper. (TNT 9/6/1953, pg. A-12)

An aerial photograph of the sprawling Pennsylvania Salt Manufacturing Co. of Washington was taken in October, 1954. The Tacoma plant, whose parent company was founded over one hundred years ago in Natrona, Pennsylvania, has been at its 40 acre Tideflats location on the Hylebos waterway since 1929. Throughout the years, it has undergone rapid expansion of its facilities and also its product lines. Despite its name, it has no connection with the manufacture of table salt.
