A builder of the field of human cytogenetics
Sometimes, a big discovery comes from a microscopic level. When Drs. Murray Barr and E.G. Bertram published an article in Nature regarding their findings of a sex chromatin body, they inspired a whole new era in research and diagnosis of genetic disorders. This discovery, later referred to as the Barr body, gave way to the discipline of genetics and established the foundation for human cytogenetics.
