Historically speaking, this disease got its name from the first founder, Hans Gerhard Creutzfeldt. He examined patients with symptoms related to brain degeneration, which lead to the naming of the disease. Afterward Alfons Maria Jakob found more information regarding the disease, and thus, the "Creutzfeldt Jakob Disease" name was born.
