Oscar Sherman Adams was an American mathematician, geodesist, and cartographer who dedicated over three decades of his professional career to the United States Coast and Geodetic Survey. Serving the agency from 1910 until 1944, Adams established himself as one of the leading authorities of his era on the mathematics of map projections.
During his tenure, Adams played a pivotal role in developing the foundational frameworks of modern American cartography. He was instrumental in the establishment of the North American Datum of 1927, a major geodetic reference system that standardized surveying across the continent. Additionally, his mathematical expertise contributed significantly to the creation of the State Plane Coordinate System, which simplified localized mapping and surveying operations throughout the United States.
