Henrietta Lacks, as HeLa, is known to present-day scientists for her cells from cervical cancer. She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells were taken without her knowledge and still live decades after her death. Cells descended from her may weigh more than 50M metric tons.
HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects; helped lead to important advances like in vitro fertilization, cloning, and gene mapping; and have been bought and sold by the billions. Yet Henrietta Lacks was buried in an unmarked grave.
