Short Summary
Carl Woese was an American microbiologist renowned for his groundbreaking work in microbiology. He is best known for discovering the third domain of life, Archaea, revolutionizing the understanding of the evolutionary tree of life. His pioneering use of ribosomal RNA sequences to categorize life forms significantly altered the scientific perspective on microbial taxonomy. Woese's work earned him numerous accolades and has left a lasting impact on the field of biology.
Early Life & Education
Carl Woese was born on July 15, 1928, in Syracuse, New York. Raised in a supportive family, he developed an early interest in science. He attended Deerfield Academy before enrolling at Amherst College, where he earned a Bachelor of Arts in Mathematics and Physics in 1950. Woese then pursued graduate studies at Yale University, obtaining a Ph.D. in Biophysics in 1953. His early academic experiences and exposure to various scientific disciplines laid the foundation for his future contributions to microbiology.
Career Highlights
Woese began his career at Yale, working under the mentorship of biophysicist Harold Morowitz. In 1964, he joined the University of Illinois at Urbana-Champaign, where he spent the majority of his career. It was there that he conducted his most significant research, focusing on the genetic coding of microorganisms. In 1977, Woese and his colleagues discovered a new group of microorganisms, Archaea, which led to the reclassification of life into three domains: Bacteria, Archaea, and Eukarya. This discovery challenged traditional views and emphasized the importance of molecular sequencing in taxonomy.
