Starting in the mid 1970s, scientific advances allowed the use of DNA as a material for the identification of an individual. The first patent covering the direct use of DNA variation for forensics (US5593832A [6] [7]) was filed by Jeffrey Glassberg in 1983, based upon work he had done while at Rockefeller University in the United States in 1981.
Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.

John M. Butler (born April 1, 1969) is a scientist and expert on forensic DNA profiling. He is a fellow at the National Institute of Standards and Technology . Since 2020, he serves as president of the International Society for Forensic Genetics .
Jeffrey Glassberg is an American biologist and author. Following a distinguished academic career he pioneered and patented work in DNA Fingerprinting. [1] [2] Later he founded the North American Butterfly Association (NABA) [3]: 22–27 [4]: 32 and is the leading proponent of moving interest in butterflies from hobbyist collecting and nets to butterflying with binoculars and cameras.
Hampikian was inducted as a Charter Fellow of the National Academy of Inventors. His inventions range from a magnetic shaped memory alloy micro-pump to a forensic DNA labeling kit that prevents contamination of samples given to the police. Hampikian pioneered the study of DNA and protein sequences absent from nature and coined the term Nullomers.
But recent advancements in forensic technology have helped investigators finally solve the mystery, the Palm Beach County Sheriff's Office said. Investigators this month identified the man as ...
Alec Jeffreys. After finishing his doctorate, he moved to the University of Amsterdam, where he worked on mammalian genes as a research fellow, [15] and then to the University of Leicester in 1977, where in 1984 he discovered a method of showing variations between individuals' DNA, inventing and developing genetic fingerprinting.
The US government's own Combined DNA Index System (CODIS) database is composed of forensic evidence assessable to local, state, and federal law enforcement officials. This database consists of genetic profiles of approximately 18 million different people, however these are limited to DNA samples from convicted felons and arrestees. [26]
