Historian Seth Rockman, author of Plantation Goods, explains how New England manufacturers, such as the Hazard brothers in Rhode Island...
Biomimicry—the practice of applying biological principles to human design—often presents as a straightforward narrative of nature-inspired innovation, yet the reality is frequently more complex. While early successes like the Shinkansen’s kingfisher-inspired nose or Mark Brunel’s shipworm-modeled tunneling shield demon...
The Brannock Device, a metal tool for measuring foot length, width, and arch length, revolutionized shoe fitting after its 1925 invention by Charles Brannock.
