J. Craig Venter, the geneticist and entrepreneur who sequenced the first microbial genome and later launched a private effort to map the human genome, died on April 29, 2026, in San Diego. He was 79 years old. The cause was cancer, according to an obituary published in The Lancet.
Venter rose to prominence in the 1990s by developing rapid gene-sequencing techniques. He founded Celera Genomics in 1998, positioning it as a commercial rival to the publicly funded Human Genome Project. The race to decode the human genome became one of the most intense scientific competitions of the era.
His laboratory sequenced the first genome of a free-living organism, the bacterium Haemophilus influenzae, in 1995. That breakthrough accelerated the field of genomics and paved the way for personalized medicine. Venter later led the team that created the first synthetic bacterial cell in 2010.
Born in Salt Lake City on October 14, 1946, Venter remained a controversial and polarizing figure in science. Critics argued that his commercial ambitions sometimes overshadowed collaborative research, while supporters praised his relentless drive to push the boundaries of biology. His death marks the end of a transformative chapter in genetics.
