Pulmonary tuberculosis is a contagious disease spread through the air via cough, spit,sneezing. If the disease is left untreated, 50% of the infected die. The classic symptoms of active TB infection are a chronic cough with blood-tinged sputum, fever, night sweats, and weight loss (the latter giving rise to the formerly common term for the disease, "consumption").
Hartley siblings, Cora and Jewel, were born about 10 years apart; Cora in 1902 and Jewel in 1912. They were the children of Tom and Sarah Coleman Hartley. The siblings mother died in 1914, leaving the young children to be raised by their father and his new wife, Della Wallace, near Crystal Springs, Copiah County, MS.
