I photographed Lucy Kalanithi for ELLE Magazine’s February 2016 issue in San Carlos, CA. Her husband, Paul, a neurosurgeon at Stanford, was diagnosed with Stage IV lung cancer at the age of 36. He set out to write a book about living a full life, and died at the age of 37 while still working on it. Lucy vowed to finish it for him. “When Breath Becomes Air” will be released January 12.
