As the U.S. war effort ramped up in the early 1940s, the Navy put out a request for chair design submissions. They needed a chair that was fireproof, waterproof, lightweight and strong enough to survive a torpedo blast. In response, engineer named Wilton C. Dinges designed a chair made out of aluminum, bent and welded to be super strong. To show off the durability of his creation, Dinges took it up to the eighth floor of a hotel in Chicago, where the Navy was examining submissions, and threw it out of the window. It bounced, but didn't bend or break. And so the Navy gave its inventor the contract, and he, in turn, opened a factory and called new his business the Electrical Machine and Equipment Company, or: Emeco. Over the decades the Emeco Navy chair became so popular that companies began to copy it. There are now tons of knockoffs -- fakes. Last month, Benjamen Walker of Theory of Everything walked 99% Invisible Host Roman Mars around New York city, pointing out real and fake Emeco chairs. 77 Steps Subscribe to SiriusXM Podcasts+ to listen to new episodes of 99% Invisible ad-free and a whole week early. Start a free trial now on Apple Podcasts or by visiting siriusxm.com/podcastsplus.  Hosted by Simplecast, an AdsWizz company.

Svalbard is a remote Norwegian archipelago with reindeer, Arctic foxes and only around 2,500 humans -- but it is also home to a vault containing seeds for virtually every edible plant one can imagine. The mountainside Crop Trust facility has thousands of varieties of coconuts, corn, rice and more, serving as a seed backup for humanity. For each crop, there’s an envelope with 500 seeds. This featured episode from the show “Endless Thread” explores an unusual reserve of invaluable resources. Plus, Emmett tells about another seed bank in more precarious part of the world.

If you live in an American city and you don’t personally use a wheelchair, it's easy to overlook the small ramp at most intersections, between the sidewalk and the street. Today, these curb cuts are everywhere, but fifty years ago -- when an activist named Ed Roberts was young -- most urban corners featured a sharp drop-off, making it difficult for him and other wheelchair users to get between blocks without assistance.
