In the mid 1980s, Kaplan met David Romanoff, the medical director of the Inglis House—a residential care facility for adults with disabilities. Two residents of the facility were diagnosed with fibrodysplasia ossificans progressiva (FOP), a very rare medical condition in which the soft tissue of the body ossifies, or turns to bone, over time. Romanoff was "grappling" with caring for the patients, and asked Kaplan if he would like to meet them, which he did.
