Not perhaps since cortisone, forty years earlier, had a molecule arrived promising so much. Chemists and transplanters, pathologists and cloners; specialists of the liver, kidney, skin, joints, eyes, bowels, pancreas, nervous system, and immune system; drug companies, insurance companies, ethicists; xenografters (people experimenting with replacing human organs with animal organs), oncologists, microbiologists, yeast specialists; people suffering from dozens of chronic, incurable diseases or at the precipice of death; and basic biologists, at the farthest remove from suffering, exploring the molecular essence of life—all were drawn to FK-506. They all wanted it—to examine, to take apart and reassemble, to experiment with, to treat with or be treated with—even though it remained largely untested, even though the first scientific paper documenting its effects on humans had yet to be published. In the world of modern medical research, where the rigors and jealousies of specialization act like water-tight bulkheads, compartmentalizing knowledge and separating those who pursue it from one another and from those they might benefit, and where the opportunities for hype are galactic, interest in the drug was broad, consuming, immeasurable, and in the early fall of 1989 focused irreducibly on one man, Dr. Thomas Earl Starzl.
