New York Hospital and Dr. Mary Engle were involved in a malpractice lawsuit regarding the hospital's participation in a 1952 Co-op study researching the relationship between oxygen and Retrolental Fibroplasia, an illness that causes blindness in premature infants. Another malpractice lawsuit was Anderson vs. New York Hospital in which a pediatric cardiac patient sued Dr. Engle. She lost both cases. The series is arranged chronologically.
