Jedidiah Morse (1761–1826) was a pioneering American geographer, often called the "father of American geography." A Congregational minister by profession, he is best known for his influential geographical publications, including Geography Made Easy (1784) and The American Universal Geography (1793), which were among the first comprehensive geographical works published in the United States. His books shaped early American understanding of geography and cartography, providing a crucial reference for educators and mapmakers. Morse's work laid the groundwork for geographic education in America, and his emphasis on detailed maps helped standardize cartographic practices during a formative period for the young nation.
