Jeffreys, Alec John. 1/9/1950 â ENGLISH GENETICIST. Alec John Jeffreys is a geneticist who is best known for the introduction of DNA analysis to forensic science. He discovered one of the most important tools for identifying human beings, genetic fingerprinting. This procedure analyzes each individual's genetic code.
Yet the criminal case uses of DNA fingerprinting were not the first to occupy Jeffreys and his team. Its usefulness in immigration cases grabbed immediate attention. A paper about DNA fingerprinting was written by Jeffreys and his team and was published in Nature in March 1985, triggering several newspaper reports.
