German General, hero and words of wisdom:

[Bear]

Kurt Gebhard Adolf Philipp Freiherr von Hammerstein-Equord
(September 26, 1878 – April 25, 1943 died of cancer) A German general who served as
Commander-in-Chief of the Reichswehr. He is a famous hero for being an ardent opponent of Hitler and the Nazi regime and also a member of the Catholic Underground.

As Chief of the Army High Command, Hammerstein-Equord oversaw the composition of the German manual on military unit command, 17 October 1933.
He originated a special classification scheme for his men:

"I divide my officers into four classes; the clever, the lazy, the industrious, and the stupid. Most often two of these qualities come together. The officers who are clever and industrious are fitted for the highest staff appointments. Those who are stupid and lazy make up around 90% of every army in the world, and they can be used for routine work. The man who is clever and lazy however is for the very highest command; he has the temperament and nerves to deal with all situations. But whoever is stupid and industrious is a menace and must be removed immediately!"
