Challenging man-made disease.

Hardy's "studies on beryllium began in 1945 when she started working for the Massachusetts Division of Occupational Medicine. She studied factories that produced fluorescent bulbs in Lynn, Salem, and Ipswich, Massachusetts. She discovered that many of the workers contracted berylliosis. Berylliosis is caused by the inhalation of dust or fumes containing beryllium. The disease presents itself with coughing, weight loss, shortness of breath, and scarring of the lungs. While beryllium was a main area of study for Dr. Hardy, throughout her career, she also studied anthrax, mercury poisoning, women's growth, and physical fitness" (Wikipedia).
