From the 1950 essay by Robert H. Jackson:
He 'read law' in the Commentaries of Blackstone and Kent and not by the case system. He resolved problems by what he called “first principles.” He did not specialize, nor did he pick and choose clients. He rarely declined service to worthy ones because of inability to pay. [...] He never quit. He could think of motions for every purpose under the sun, and he made them all. [...] The law to him was like a religion, and its practice was more than a means of support; it was a mission. He was not always popular in his community, but he was respected. [...] He “lived well, worked hard, and died poor.” Often his name was in a generation or two forgotten. It was from this brotherhood that America has drawn its statesmen and its judges.
