By the end of his life, Ovshinsky had established a new field of science: the study of “amorphous” materials, messy solids that have no regular atomic structure. He published around 300 academic papers on the subject. His inventions gained more than 400 patents. All this from a man who taught himself physics using books borrowed from the public library in his home town of Akron, Ohio.
The technology behind rewritable CDs and DVDs was Ovshinsky’s brainchild, as was the material for “phase-change memory”, now standard in data storage technologies today.He designed the solar panels used in the Japanese calculators that flooded the world market in the 1980s. Similarly ubiquitous is his rechargeable nickel-metal hydride battery.
As one of the first people to spot that burning fossil fuels would lead to global climate change, Ovshinsky geared much of his research towards steering us away from that future. His altruism was unbounded: he threw ideas to anyone who would listen. Nevill Mott, on receiving his Nobel Prize in Physics in 1977, admitted that he got some of his best ideas from Ovshinsky.
