 Friedrich Robert Helmert

Friedrich Robert Helmert (1843-1917) was a German mathematician and geodesist known for his contributions to the field of geodesy, which is the science of measuring and understanding the Earth's geometric shape, orientation in space, and gravity field. He is particularly recognized for developing methods for the accurate measurement and representation of the Earth's surface and for formulating the Helmert transformation, a mathematical technique used to relate different coordinate systems in geospatial studies.
