Hamilton O. Smith: The Nobel Laureate Revolutionizing Genomics
Restriction Enzymes and Beyond
Hamilton O. Smith is a renowned American microbiologist and Nobel laureate, best known for his groundbreaking discovery of type II restriction enzymes, which earned him the Nobel Prize in Physiology or Medicine in 1978. This pioneering achievement has had a profound impact on the field of molecular biology, enabling scientists to manipulate DNA with unprecedented precision.
Early Life and Education
Born on August 23, 1931, in New York, Smith grew up with an innate curiosity for the natural world. He attended University Laboratory High School of Urbana, Illinois, before moving to the University of Illinois at Urbana-Champaign. Smith later transferred to the University of California, Berkeley, where he earned his B.A. in Mathematics in 1952. He then pursued his medical degree from
Johns Hopkins School of Medicine, graduating in 1956.
Career Highlights
- 1956-1957: Smith worked for the Washington University in St. Louis Medical Service.
- 1970: He discovered the first type II restriction enzyme, HindII, alongside Kent W. Wilcox.
- 1975: Smith was awarded a Guggenheim Fellowship, which he spent at the University of Zurich.
- 1995: He led a team at The Institute for Genomic Research in sequencing the first bacterial genome, that of Haemophilus influenzae.
Genomics and Synthetic Biology
Smith's pioneering work in genomics has been instrumental in the advancement of the field. He played a key role in the sequencing of many early genomes at The Institute for Genomic Research and contributed to the assembly of the human genome at Celera Genomics. In 2003, his team synthetically assembled the genome of a virus, Phi X 174 bacteriophage. Today, Smith is the scientific director of Synthetic Genomics, a privately held company founded by Craig Venter in 2005.
Awards and Honors
