The Zinsmaster Baking Company began in Duluth in 1913 as the Zinsmaster-Smith Bread Company, Harry W. Zinsmaster and R. F. Smith partners. The small local enterprise grew to one of national importance. Principal company staff retired in 1977 and 1978, and Zinsmaster was acquired by Metz Baking Company in January 1978.
