Oliver Smithies (23 June 1925 – 10 January 2017) was a British-American geneticist and physical biochemist. He is known for introducing starch as a medium for gel electrophoresis in 1955, and for the discovery, simultaneously with Mario Capecchi and Martin Evans, of the technique of homologous recombination of transgenic DNA with genomic DNA, a much more reliable method of altering animal genomes than previously used, and the technique behind gene targeting and knockout mice. He received the Nobel Prize in Physiology or Medicine in 2007 for his genetics work.
