Johann Jacob Baeyer

Johann Jacob Baeyer was a 19th-century German geodesist and mathematician known for his significant contributions to the science of geodesy, which is the study of Earth's shape, size, and gravitational field. He is best remembered for developing precise measurement techniques and promoting triangulation methods, which involve measuring angles in triangles formed by points on the Earth's surface. His work laid foundational principles for accurate map-making and surveying, advancing our understanding of Earth's dimensions and surface. Baeyer's innovations helped improve navigation, boundary delineation, and the overall science of cartography.
