Long before becoming a haven for software and biotech giants, Kendall Square was a center for manufacturing during the era of steam. Here, in the 1860s, two crucial advancements emerged: the standardization of threaded iron pipes and fittings for use in household plumbing, gas fixtures, and steam power and the invention of the modern pipe wrench that allows us to work on them. This episode explores the story behind the Stillson pipe wrench, a tool so revolutionary that its inventor’s name became synonymous with pipe wrenches and so innovative that its design remains nearly unchanged over 150 years later. We’ll meet Daniel Chapman Stillson, the Civil War veteran and ingenious machinist who, frustrated by the limitations of existing tools, designed an adjustable pipe wrench that revolutionized plumbing, pipefitting, and his employer, the Walworth company.
