Original British linen-backed patent lithograph for Albert Einstein and Leo Szilard's invention of an apparatus for "Electrodynamic Movement of Fluid Metals particularly for Refrigerating Machines," one page, 12.25 x 10.5, May 26, 1930. The diagram features multiple views of the apparatus, an electromagnetic pump in which fluid metal moves under the influence of a magnetic field to compress a refrigerant. The top border reads: "303,065 Complete Specification." The lower border features the printed text: "Charles & Read Ltd. Photo Litho." The left border reads: "This Drawing is a reproduction of the Original on a reduced scale." Includes the printed British "Patent Specification" document, one page both sides, which describes the process used by the apparatus. The specification sheet bears a "U.S. Patent Office Library" ink stamp. In very good to fine condition, with chipping and several tears to the specification sheet.

Although the 'Einstein-Szilard Refrigerator' was patented worldwide, it never became a consumer product. Einstein and Szilard's most famous collaboration was a 1939 letter to President Franklin D. Roosevelt in which they warned that Germany might develop atomic bombs and suggested that the United States begin its own nuclear program. In hindsight, Einstein regretted signing the letter and famously became an outspoken opponent of nuclear weapons.
