Dupuis, N. F. (Nathan Fellowes), 1836-1917

N. F. Dupuis, also known as Nathan Fellowes Dupuis, was an American mathematician and educator recognized for his contributions to the field of trigonometry. His works primarily focused on practical applications of mathematical principles, making them accessible to students of practical sciences. Dupuis authored several notable texts, including 'A Brief Treatise on Plane Trigonometry' and 'An Elementary Treatise on Spherical Trigonometry.' These works were designed to aid students in understanding the essential concepts of trigonometry, particularly in relation to fields such as geodesy and astronomy. Dupuis's approach emphasized the practical side of mathematics, reflecting a pedagogical commitment to equipping students with the tools necessary for real-world applications. His treatises not only served as educational resources but also contributed to the broader discourse on the importance of mathematics in scientific inquiry during the late 19th and early 20th centuries. Through his writings, Dupuis played a significant role in shaping the curriculum for practical science students, leaving a lasting impact on mathematical education in America.
