Biography
Oliver Smithies (23 June 1925 – 10 January 2017) was a British-American geneticist and physical biochemist who made pioneering contributions to molecular biology, earning him the 2007 Nobel Prize in Physiology or Medicine. Born in Halifax, England, Smithies showed an early interest in science that would define his career for more than sixty years. He studied at Balliol College, Oxford, where he gained the foundational knowledge for his groundbreaking work in genetics and biochemistry.
His major contribution was developing techniques for homologous recombination to modify animal genomes. Collaborating with Mario Capecchi and Martin Evans, he found ways to accurately target specific genes in mouse embryonic stem cells. This allowed scientists to create knockout mice with certain genes disabled, making it possible to understand gene function and study human diseases in lab animals. The accuracy of homologous recombination was a big improvement over the earlier random and unreliable genetic modification methods.
Earlier in his career, in 1955, Smithies introduced starch gel electrophoresis, a key tool for separating proteins and other molecules based on size and electrical charge. This technique became widely used in labs around the world and was essential for protein analysis, advancing the understanding of protein structure and function.
Smithies received numerous prestigious awards for his work. Besides the Nobel Prize, he was awarded the Albert Lasker Award for Basic Medical Research in 2001, the Wolf Prize in Medicine in 2002, and the Canada Gairdner International Award in 1993, among others. He married Nobuyo Maeda and spent his later career years in the United States, passing away in Chapel Hill, North Carolina in 2017. His work fundamentally changed genetic research and still influences modern molecular biology and medical research today.
Before Fame
Growing up in Halifax in the 1930s and 1940s, Smithies reached adulthood during World War II when scientific research focused more on practical uses for the war. He attended Balliol College, Oxford in the post-war years when British universities were putting greater effort into scientific research and working together internationally.
Genetics was changing quickly in the 1950s and 1960s during Smithies' early career. The discovery of DNA's structure by Watson and Crick in 1953 opened up new ways to understand heredity at the molecular level. This gave innovative researchers like Smithies the chance to develop new methods for studying genes and proteins. In 1955, he introduced starch gel electrophoresis at a time when biochemists badly needed better ways to analyze biological molecules.

Did You Know?
- 01.He developed starch gel electrophoresis while working with potato starch, which became a standard laboratory technique used worldwide for protein separation
- 02.His knockout mouse technique was initially met with skepticism by the scientific community until its practical applications became evident
- 03.Smithies shared his 2007 Nobel Prize with two other scientists, Mario Capecchi and Martin Evans, who independently developed similar gene targeting techniques
- 04.He continued conducting research well into his 80s, maintaining an active laboratory until shortly before his death
- 05.The gene targeting technique he developed is now used to create animal models for studying human diseases including cancer, diabetes, and neurological disorders
