Story summary

David Botstein died on February 27 in Palo Alto, California, at age 83 from Parkinson's disease.
Botstein developed a method to locate genes in human DNA, enabling the identification of disease-causing genes and the mapping of the human genome.
His breakthrough occurred in 1977 during yeast experiments, where he found that small DNA variations could serve as markers for nearby genes.
His work laid the foundation for understanding human genetics and addressing complex inheritance issues, such as hemochromatosis.
