Westmoreland Specialty Company was an offshoot of the Specialty Glass Company as the business moved from East Liverpool, Ohio to Grapeville, Pennsylvania during the late 1880s. Charles and George West were the company’s founders, as well as the majority shareholders. Westmoreland mainly produced glass containers for vinegar, mustard and lemon flavoring during the early 1900s. They also produced candy jars during World War I.
Westmoreland Specialty Company became Westmoreland Glass Company in 1924, to avoid confusion about products the company was producing. At that time, glass was the only product being produced in the factory at Grapeville.
During the Depression in the 1930s, the Westmoreland Glass Company did not cease production, although the company did suffer financially. In 1937, the Westmoreland Glass Company reorganized with supplemental funds provided by the Brainard family who had been partners with the West family since the late 1800s.
In the same year, James J. Brainard became president of the company and was succeeded by his son James H. Brainard when he died in 1953.
