On June 26, 2000, the physician Francis Collins, then the director of the National Human Genome Research Institute, stepped up to the podium in the East Room of the White House in front of President Bill Clinton, high-ranking U.S. officials, and foreign dignitaries. A team of more than a thousand scientists, led by Collins, had just assembled a first draft of the three billion letters in the human genome. Clinton called this a "stunning and humbling achievement," rivalling Galileo's. Collins told the audience, "We have caught the first glimpse of our own instruction book, previously known only to God." By 2003, he would bring the Human Genome Project, one of the largest scientific collaborations in history, to a successful completion, nearly half a billion dollars under budget and two years ahead of schedule.
