Born in Cambridgeshire, England, in 1838, William Fisher came to America as a boy of 10. His family settled along the Mississippi River near Clinton, Iowa. Young William distinguished himself as a mechanic in a small engine shop and learned as much as he could about steam, the major source of power at that time. In 1876, at age 38, William accepted a job as the chief engineer for the city of Marshalltown, Iowa, and helped install the water works. When a raging fire threatened the levee area of town, William was called from his home to maintain water pressure for the town’s firemen. Exhausted from handthrottling the steam-driven pumps through the night, he felt there must be a better way to control the pumps and maintain them at a constant pressure. Many months and trials later, he was satisfied with one of his product designs—the Fisher Type 1 constant pressure pump governor (which is actually a regulator). In 1880, he applied for a patent and began to manufacture his invention in a building on the corner of First Avenue and Linn Street.
