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.
The years following the war exploded with developments, including techniques for lifting fingerprints using a tape-lifting method, voiceprint identification and perhaps the most famous discovery in the history of forensic science, the discovery of the unique structure of DNA by Watson and Crick in 1953.
