Arthur Lazarus, Jr.

    The firm of Sonosky, Chambers, Sachse, Endreson & Perry, LLP is sad to announce the passing of Arthur Lazarus, Jr.  Arthur’s contribution to our firm and to Indian law was enormous.  He established the first Indian law practice at a large firm in D.C. when he was a partner at Fried Frank.  He was an outstanding litigator – as the United States Supreme Court’s decision in the Sioux Nation case demonstrates, which was only one of his many successes.  When Arthur joined us – at Marvin Sonosky’s urging after Arthur had retired from Fried Frank –  he was a giant in the field, and brought a wealth of experience, judgment, and warm collegiality to the firm.  He was humble, respected others and their views, and listened carefully when they spoke.  His character and professionalism exemplified the importance of civility in law practice, which enables one to treat other lawyers with the dignity and respect to which all persons are entitled, while at the same time addressing matters of law through advocacy.  He relied on the law and his integrity to advance the legal position that his great mind had concluded was best.  He never sought to make his points other than by reason and persuasion.   And when others sought to answer his argument by other means, it did not distract him to realize that they had no better answer to what he had said.  All of us are privileged to be part of a firm that has a place in Arthur’s great legacy.
