Dr. Barbara Beattie, a Littleton native and the daughter of William Johnson Beattie (co-founder of Littleton Hospital) was one of the first women doctors in New Hampshire. She was born in 1897, graduating from Littleton High School in 1914, and from Vassar College in 1920. She obtained her medical degree from the Cornell Medical School and interned at the New York Infirmary. She began her practice in Littleton in 1929 and became an authority in pediatric care. In 1938 she became a fellow of the American Academy of Pediatrics. She was the first woman appointed to the New Hampshire Board of Health.
Dr. Beattie was instrumental in beginning school health and immunization clinics. She was a public school physician in Littleton, Bethlehem and St. Mary's School. She was also noted as being the first woman to own her own aircraft. She probably flew from an airstrip in Littleton's Apthorp village in a single engine plane. Her own health was poor and she died at age 58 on May 22, 1955.
