Curiously -- or not, depending on your level of knowledge of the Nazis -- many of the top Nazis including Adolf Eichmann, Adolf Hitler, Heinrich Himmler, Josef Goebbels, and others were, to say the least, not exactly ideal specimens of the Nordic European racial type.
In fact, they do not look Nordic/Germanic at all, with black hair, swarthy complexions, and facial structures demonstrating jewish or other non-white ancestry.
Eichmann's face and head structure display some strong Jewish characteristics.
1) Characteristic Jewish pattern of baldness, which forms a strong "ruff" around the back of the head.
2) Curly dark hair. Even though he doesn't have much hair, what he does have is kinky and refuses to lay down.
3) Brachycephalic. This is a broad forehead that recedes quickly from the browline back. This occurs in Whites as well, but is much less common.
4) Long nose. The trademark Jewish feature is a nose that is very long in proportion to the face.
5) Thickness at midsection of nose. Jewish noses quite often are thin at the bridge, then flare out in the midsection.
6) Nose tip has exaggerated "V" shape.
7) Large projecting ears with large lobes.
8) Very strong lines around the mouth. This, combined with large lips and underlying muscles lends a beaky aspect to the face that is especially common in Jews.
9) Protruding lower lip. Eichmann doesn't have large lips, but it's clear that his lower lip protrudes slightly.
10) Mouth often looks loose and irregular. Clearly Eichmann has a loose irregular mouth.
11) White line along edge of top lip, and often a crease along edge of lower lip.
12) Puffy, soulful eyes, often slanted down on the corners. Eichmann definitely has the soulful eyes.
Eichmann was of small stature, a feature common to Jews. 
Reportedly, Eichmann spoke Yiddish and showed interest in Zionism, visiting Zionists in Palestine many times, and even collaborated with Mussolini and the Jews in Palestine to set up Irgun training camps. 
According to Hennecke Kardel, in his book Adolf Hitler: Founder of Israel, Eichmann was a full-blooded Jew.
