Twee aanblikken van een voetzool met symptomen van syfilis before 1894

"Twee aanblikken van een voetzool met symptomen van syfilis" (Two views of a sole with symptoms of syphilis), is a medical illustration created by Albert Ludwig Sigesmund Neisser, a German physician who discovered the bacterium responsible for gonorrhea and made significant contributions to the understanding of syphilis. This illustration shows the two views of a foot affected by the disease. It's a rare example of Neisser's visual documentation of the disease and its impact on the human body. Created before 1894, it serves as a historical testament to the impact of the disease and the importance of early diagnosis.
