The name Albert Einstein has become a byword for genius – and rightly so. In 1926 Einstein read a newspaper article about a Berlin family who had died in their sleep when their refrigerator sprung a leak. In total Einstein and Szilard were granted 45 patents covering three different refrigerator designs. But while this is the best-known of the Einstein-Szilard refrigerators, it is the pair’s second design which most excited Einstein. Born in Budapest in 1898, Szilard spent the early part of his career in Germany, where in addition to helping Einstein design refrigerators he also independently invented and patented the linear particle accelerator, the cyclotron, and the electron microscope.
