CATHRALL 202 CHADWICK Cathrall, Isaac (1763-1819) A native of Philadelphia, where he was born in 1763, Isaac Cathrall studied medicine under Dr. John Redman, then went abroad to add to his knowledge in London, Edinburgh and Paris. During the yellow-fever epidemics of 1793, and 1797-9 he distinguished himself by re- maining in the city and doing valiant work, losing no opportunity to study also the disease scientifically and performing autopsies on some of the victims. The results of these studies were embodied in several publications, and in 1802 he, with Dr. William Currie (q. v.), pub- lished their observations on an epidemic fever prevailing that year in Philadelphia. He also wrote a medical sketch of the "Synochus Maligna or Malignant Contagious Fever as it lately appeared in the city of Philadelphia," 1794, and edited "Buchan's Domestic Medi- cine, adapted to the Climate and Diseases of America," Philadelphia, 1797. He was a sur- geon of the city almshouse from 1810 to 1816. He died on the twenty-second of Febru- ary, 1819, of apoplexy; and Thacher describes him as "a well-bred gentleman of rigid morality and inflexible integrity." Francis R. Packard. Amer. Med.

He was collaborator for the state of Vermont for the Cyclopedia of American Medical Biography, Philadelphia, 1912, furnishing many excellent biographies. Dr. Caverly married Mary Alice Tuttle, who survived him ; their son, Harley T. Caverly, died in 1910 while taking a post-graduate course in medicine at the Johns Hopkins Uni- versity. Of Dr. Caverly it is said : "It is character- istic of the man that he died fighting, cut down by the scourge of influenza, against the epi- demic of which in Vermont he was active, he assumed responsibility in the work of preven- tion and took personal charge, rendering wise and effective aid." But his own life paid the cost, for he died, after an illness of three days, on October 16, 1918. Howard A. Kelly. The Vermonter, 1918, vol. xxiii, 254-261. Portrait.
