The youngest of eight children, Dr. Hallie Earle was born on the outskirts of Waco on September 27, 1880. She graduated from Baylor University in 1901 with a bachelor's degree and received her master's degree the next year before enrolling at Baylor Medical School in Dallas. Earle, the only woman in the medical school, earned an M.D. in 1907. She worked as a doctor in Marlin and Waco from 1908 to 1948 and when she retired, she was one of only a handful of female doctors in the area. The U.S. government named Dr. Earle a Cooperative Weather Observer in 1916 due to her comprehensive weather observation journals. She passed away on November 1, 1963, in Waco.
