Thomas D. Brock

Thomas D. Brock was an influential American microbiologist known for his pioneering work in studying microorganisms in extreme environments, particularly hot springs. He discovered and characterized Thermus aquaticus, a heat-resistant bacterium that produces an enzyme called Taq polymerase, essential for the polymerase chain reaction (PCR) technique widely used in DNA research and medical diagnostics. Brock's research significantly advanced the fields of microbiology, genetics, and biotechnology, making it possible to amplify DNA for various applications, including genetic testing and forensic science. His contributions have had a lasting impact on science and medicine.
