What happened
The Human Genome Project was a large, well-organized, and highly collaborative international effort to generate the first sequence of the human genome, the full set of genetic instructions for a human being. It officially began on October 1, 1990, when the NIH allocated the first funds toward developing the approaches, technologies, and resources needed to map and sequence the genome. On June 26, 2000, the International Human Genome Sequencing Consortium announced that it had completed a working draft of the sequence. On April 14, 2003, the consortium announced the successful completion of the project, more than two years ahead of schedule, and by a coincidence of timing the finished sequence arrived essentially fifty years after the double helix was described.
Why it matters
Reading the human genome gave medicine a reference text for human biology, accelerating the search for the genetic roots of disease, the development of targeted therapies, and the field of genomics. Because it was publicly funded and its data released openly, it also set an influential precedent for sharing foundational biomedical information rather than locking it behind patents.
How we know
The project's start in 1990, the 2000 working draft, and the 2003 completion are documented by the NIH National Human Genome Research Institute, which coordinated the U.S. effort and maintains the official timeline and records.
