America lost a great Maker last week. Stanford R. Ovshinsky was a self-taught engineer and inventor who held more than 400 patents when he died on October 17th at the age of 90. The name may not be familiar to you, but his work is. Ovshinsky is credited with inventing key technologies behind flat-panel liquid crystal displays that we use to watch TV, work on the Internet, or play with our phones.
He was also the inventor of the nickel-metal hydride battery — a rechargeable battery that now powers everything from laptops to the Prius. Ovshinsky (along with his wife, Iris, who held a Ph.D. in biochemistry and was his research partner for much of his life), began working on improved versions of batteries, solar cells, and other energy technologies beginning in the early 1960s. More than a decade before climate change became a well-established fact, Ovshinsky was concerned about the pollution and political instability that went along with fossil fuels. He spent the rest of his life developing better alternatives.
For a good introduction to how truly groundbreaking Ovshinsky's ideas were, check out a 1978 article from Popular Science, all about his invention of amorphous silicon semiconductors — a technology that today forms the basis behind both thin-film solar panels and smart phone displays. At the time though, it made Ovshinky a controversial figure.
