Who developed the Unified Soil Classification System?

The Unified Soil Classification System (USCS) was developed by Arthur Casagrande during the 1940s. This system was designed to provide a coherent method for classifying soils based on both their physical and engineering properties. Casagrande's work was instrumental in creating a standardized classification that could be used for various engineering applications, particularly in civil and geotechnical engineering. The framework established by the USCS provides engineers and soil scientists with a clear vocabulary and methodology for differentiating soil types, which aids in understanding their behavior under load and their suitability for construction purposes. The contributions made by other figures, such as Atterberg with his plasticity concepts, and the Mohr-Coulomb and Coulomb theories pertaining to soil mechanics, complement soil classification systems but do not represent the foundational work of USCS. This context reinforces why the correct answer is linked specifically to Arthur Casagrande, as he is recognized for his significant contributions to the development and implementation of this classification while the others focus on different aspects and criteria within soil science and mechanics.
