Figure 7 (Small)

Figure 7. (left) Ernst Unger of Berlin (1875-1938). This cartoon was all I was able to find by way of an illustration of him. Unger worked alone in a privately-funded laboratory clinic, and in 1910 he used the two kidneys of a macaque pigtailed monkey transplanted en bloc into a young woman in advanced renal failure (right). This technique is used for young paediatric donors today.
