I ran across an interesting piece of history while doing some research on molecular models. From the business section of the November 2nd, 1961, edition of Jet magazine...
I wasn't able to find much else on Metaloglass or Dr. Szagedy, but a collector has posted some photos of his ball-and-stick crystal structure models. They had plastic (phenolic resin?) balls and featured some interestingly sparse rods (steel).
An antiques dealer also had posted a collagen model built by Metaloglass, which looks absolutely beautiful.
It's good to remember that what usually remains after we're gone is the work we've done and the stands we've made.
