Noah Webster, Proto Epidemiologist: 

Pedant, Pestilence & Politics

Noah Webster (1758-1843), best known for the dictionary that bears his name (1828), was also an educator, newspaper editor, lawyer, and politician, and he advocated for universal education, social welfare, and public health.  Less well known are his efforts to understand the causes and prevention of diseases such as yellow fever that plagued the young nation,  Though not a physician, between 1796 and 1800 Webster published two books and many articles on disease, public health, yellow fever, and quarantine, and this work catalyzed the creation of the first U.S. medical journal, The Medical Repository (1797-1824).  

In the 1790s, the young Republic faced yearly yellow fever epidemics. Webster sought to the understand these outbreaks by gathering numerical data, and his work influenced figures like Benjamin Rush and Thomas Jefferson and made lasting contributions to American medical thought. Webster’s extensive data collection emphasized the relationship between cosmic and environmental factors on epidemics. As interest in public health and health statistics grew, Webster became, for both physicians and public health officials, a forerunner of a scholar who, fifty years later, would be called an “epidemiologist.” My research explores Webster’s medical writings, their publication challenges, and contemporary responses. Sources include the Noah Webster Papers at the New York Public Library, the Library Company of Philadelphia, and collections at Yale and Harvard. Key questions addressed are why Webster engaged in this medical debate, his methods for gathering data, contemporary reactions, and the impact of his work. Additionally, I examine his unpublished revisions of A Brief History of Epidemic and Pestilential Diseases (1799), held at the New York Public Library.
