They first laid eyes on one another in the spring of 1986, when they were both admitted to the cystic fibrosis wing of Dallas’ Presbyterian Hospital. Kimberley Marshall was then sixteen, thin and winter-pale and beautiful, her red hair falling down the back of her pink nightgown patterned with little white hearts. David Crenshaw was eighteen; he wore his usual hand-me-down T-shirt and faded gray pajama pants and oversized glasses that turned dark in the sunlight. David would stand at one end of the hospital hallway, hoping Kim would come out of her room at the other end.
“No way,” the wing’s respiratory therapist, Doug Kellum, would say. “No way she’s going to look twice at you.”
Kim was known among the nurses as the princess. She came from a polished North Dallas family. She loved Tiffany perfume, Lancôme makeup, and clothes from Neiman Marcus. She would sit for hours in her hospital bed, reading romance novels. David, on the other hand, was famous for his bad grammar and coarse jokes. When a female nurse walked past his room, he would lean forward in his bed and shout, “Shake it, baby, don’t break it.” On Saturday nights when he wasn’t in the hospital, he raced midget cars at a local dirt track. “Can you name just one other race car driver in this country with cystic fibrosis?” he proudly asked Kellum. “Let me tell you, there ain’t one.”
“She still isn’t going to talk to you,” Kellum replied.
It was hard enough to imagine a love affair developing between two cystic fibrosis patients, let alone one between Kim and David. A baffling genetic disorder that produces a sticky phlegmlike mucus that clogs the lungs and digestive tracts, CF afflicts at least 30,000 young Americans—1 out of every 2,000 people. Sometimes the disease kills quickly, choking the air out of bewildered little children. Other times it attacks when its victims are in their teens or twenties, causing respiratory infections, pneumonia, dehydration, and gastrointestinal complications. Like a brilliant serial killer, CF is unstoppable: Although an array of pulmonary treatments and medicines now allows patients to live more productive, pain-free lives, few survive into their thirties. As one doctor has said, trying to get rid of the mucus is like sweeping spilled molasses off the floor with a broom.
Nevertheless, Kim Marshall did finally go out on a date with David Crenshaw. Then, six months later, to the shock of their families, friends, and doctors, Kim and David announced their engagement.
“Both of you are sick,” David’s father told him, pleading with his son to reconsider. “You’re sick! You two can’t possibly take care of yourselves.”
“Do you realize what will happen?” Kim’s mother asked her tearfully. “Do you realize that one of you is going to die in the other’s arms?”
Staring down such a death sentence, 21-year-old Kim Marshall wobbled down the aisle of Lovers Lane United Methodist Church in Dallas on October 27, 1990, and declared her love for 23-year-old David Crenshaw—the first known marriage in America between CF patients. To some in attendance, the wedding was a rash, starry-eyed act of youth. “They’ve set themselves up for a tragedy,” a fellow patient told me.
Kim and David, however, insisted that they had a right to be together—“just like normal people,” Kim said not long after the wedding, when I interviewed her for a
