The Electrical Machine and Equipment Company (Emeco) was founded in 1944, in Hanover Pennsylvania. During WWII the U.S. commissioned Emeco to make a lightweight but strong chair that could take a beating from water, salt, air, sailors, and maybe a missile. They answered that challenge with the 1006, a chair handmade of recycled aluminum, that takes 77 steps to build. The 1006 is still in production today and is made to last a lifetime.
Emeco has a great Vimeo page with a bunch of videos showing how their excellent chairs are made.
