I had the privilege of interviewing 80 scientists and luminaries to document their stories. for the David J. Sencer CDC Museum Global Health Chronicles Oral History of Polio Project. In doing research to prepare for the interviews, I was surprised to find that there was no biography of Albert Sabin, developer of the oral polio vaccine. But I found that when I asked interviewees if they had known Sabin, people who knew him didn’t have to tell me—it was revealed first in their facial expressions and coloring. Then hands might run through hair or cover a smile as they remembered their Sabin encounters or stories from others about him. One scientist showed me a copy of the 40-year-old manuscript with red hand-written comments Sabin used to tear apart the paper he wrote. But each recounted Sabin experience ended with admiration of his scientific excellence along with what the researchers learned from him and passed on to others. The stories making up Sabin’s unique life journey and the scientific principles by which he lived are worth preserving for present and future generations. Five years ago with the help of scores of others, I began.
