Short Summary
George Beadle was a prominent American geneticist and Nobel laureate renowned for his groundbreaking work in the field of genetics. He is most famous for his "one gene-one enzyme" hypothesis, which laid the foundation for modern molecular biology. Beadle's pioneering research significantly advanced the understanding of gene function and its relation to biochemical processes. His contributions have left a lasting impact on genetics, influencing countless scientific developments in the field.
Early Life & Education
George Wells Beadle was born on October 22, 1903, on a farm in Wahoo, Nebraska. His early life was steeped in agriculture, which fostered an interest in biology and the natural sciences. Encouraged by his parents, Beadle pursued higher education at the University of Nebraska, where he earned his bachelor's degree in 1926 and his master's degree in 1927. Influenced by his professors, he moved to Cornell University for his Ph.D. studies, completing his doctorate in 1931. His experiences during these formative years shaped his scientific curiosity and set the stage for his future contributions to genetics.
Career Highlights
Beadle's career began with a focus on maize genetics at Cornell University, where he worked with Nobel laureate Rollins Emerson. He later joined the California Institute of Technology, collaborating with geneticist Thomas Hunt Morgan. At Caltech, he met Edward Tatum, and together they conducted seminal experiments on Neurospora crassa, leading to the formulation of the "one gene-one enzyme" hypothesis. He went on to serve as the chair of the Biology Division at Caltech and later as the President of the University of Chicago. Throughout his career, he made significant contributions to the understanding of genetic processes and their biochemical pathways.
