By developing several automated biotechnical instruments, Leroy Hood played a crucial role in the biotech industry. His DNA gene sequencer greatly accelerated the Human Genome Project during the 1990s. By enabling scientists to map the 25,000 genes that make up a human being, Hood revolutionized biomedical research.

Invention Impact

While pursuing his Ph.D. at the California Institute of Technology, he became inspired to develop a machine that would automate protein sequencing. Hood and his team created a machine one hundred times more sensitive than previous devices and allowed scientists to analyze proteins previously impossible to isolate in large amounts.

Hood and his colleagues also developed a protein synthesizer, which enabled the production of long proteins in high, consistent yields, and a DNA synthesizer which made it practical to synthesize DNA fragments for use in sequencing and cloning even complete genes. He also developed the ink-jet synthesizer which synthesized DNA chips.

Born in Missoula, Montana, Hood earned his M.D. from the Johns Hopkins School of Medicine and his Ph.D. from Caltech. He is the recipient of many awards including the Lasker Award, the Kyoto Prize and the Lemelson-MIT Prize.
