The high-tech economy of Greater Boston did not emerge in a vacuum; it was built directly upon the physical and cultural foundation of the American Industrial Revolution. The same geographic advantages, machine-shop traditions, and capital networks that powered the textile mills of Massachusetts’ Charles and Merrimack Rivers in the nineteenth century supported electronic and software manufacturing in the twentieth century. This series of clips explores those structural continuities. Pioneers discuss how working in historic mill spaces influenced their operations and trace how the region's long-standing precision-engineering mindset adapted to the demands of vacuum tubes, semiconductors, and digital code, revealing the long historical arc that binds Francis Cabot Lowell’s Waltham mill to modern New England’s high-tech hubs.
