African-American woman (1920–1951), source of HeLa immortal cell line
Henrietta Lacks was an African-American woman whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line and one of the most important cell lines in medical research. An immortalized cell line reproduces indefinitely under specific conditions, and the HeLa cell line continues to be a source of invaluable medical data and research to the present day.
