Venter accelerated the race to sequence the human genome, promoted the shotgun sequencing method, led marine genomics research, and was one of the central figures in the birth of synthetic biology.
J. Craig Venter, one of the most influential scientists in the modern genomics revolution, died on April 29, 2026, in San Diego at the age of 79. According to a statement from the J. Craig Venter Institute, he died after a brief hospitalization due to unexpected side effects from treatment for a recently diagnosed cancer. (J. Craig Venter Institute)
Venter was a scientist, entrepreneur, and extraordinary public figure in the world of biology. He is best known for his role in the race to sequence the human genome, but his contributions went far beyond a single project. Throughout his career, he pushed the field of genomics into an era of speed, automation, computationalism, and competition between public and private laboratories. The journal Nature described him as having helped reshape the boundaries of biology: from sequencing DNA at unprecedented speed, to creating organisms with synthetic genomes, to mapping the genetic diversity of ocean microbes.

The Human Genome Project – Private Version
Venter burst onto the scientific scene in the 1990s, when he was among the leaders of the effort to sequence entire genomes at high speed. In 1995, he co-published the first fully sequenced bacterial genome, an achievement that marked the beginning of a new era in genetics and computational biology. He later founded Celera Genomics, a private company that competed with the public Human Genome Project and used whole-genome shotgun sequencing: the parallel sequencing of many DNA segments and their reassembly using computing power.

The race between Celera and the public consortium became one of the great stories in the history of science at the end of the 20th century. In June 2000, the draft of the human genome was presented at the White House, at an event where Venter and Francis Collins, who led the public effort, appeared together. The main scientific publications appeared in 2001, simultaneously in Science and Nature. Alongside criticism of Venter's commercialism and aggressive style, many researchers now acknowledge that the competition accelerated the decoding of the human genome in the years. Professor John Hardy of University College London described him as "an important and controversial figure", and noted that the competition greatly accelerated the completion of the human sequence.

Activate a bacterial cell using a synthetic chromosome
Venter then continued to push the boundaries of biology in new directions. He led ocean research expeditions, including the Global Ocean Sampling Expedition, that examined the vast genetic diversity of marine microbial communities. He was also a key figure in the birth of synthetic biology. In 2010, a team from the Venter Institute announced that it had managed to activate a bacterial cell using a synthetic chromosome—a step that was seen as a milestone in the ability to build and program biological systems.
Venter was no ordinary scientist. He was a lab technician, an entrepreneur, a fierce competitor, and a man who saw genomics not just as a field of research but as the foundation for the future of medicine, energy, and biotechnology. In later years, he also became involved in longevity research, co-founding Human Longevity, a company that attempted to combine genetic sequencing, medical data, and artificial intelligence to understand diseases related to aging.
Venter’s legacy is complex. He provoked opposition because of his sharp combination of science, business, patents and media competition. But it is difficult to overstate his influence on the way biology is done today. Modern genomics laboratories, personalized medicine, microbiome research, synthetic biology and large-scale DNA analysis all bear traces of the revolution that Venter was one of the main instigators.
His death marks the end of an important chapter in the life sciences: the transition from biology that described living things from the outside, to biology that measures, classifies, compares, and sometimes even attempts to rebuild the internal code of life.
