Who advocated for an originated hospital corps as early as 1893?

Navy Surgeon General J.R. Tryon was a pivotal figure in advocating for the establishment of a hospital corps within the Navy as early as 1893. His vision was to create a structured medical service that would improve the care provided to sailors and marines, emphasizing the need for trained medical personnel to operate effectively within the military context. This initiative laid the groundwork for the eventual establishment of the Hospital Corps officially in 1898, which significantly improved medical support in the Navy.

Other historical figures mentioned, such as President William McKinley, Admiral Chester W. Nimitz, and General George S. Patton, contributed to military and naval advancements in their own ways, but it was J.R. Tryon's specific advocacy that directly led to the creation of the hospital corps as a recognized entity in the Navy, making him the key individual in this context.
