Q: Question: What town was the US Supreme Court Justice that worked at the same firm Milton Shadur worked at starting in 1949 from? Passage 1:Shadur was born in Saint Paul, Minnesota, and raised in Milwaukee, Wisconsin, where he attended Washington High School, alma mater of fellow future attorneys Newton N. Minow and Abner J. Mikva. Shadur received a Bachelor of Science degree in Mathematics and Physics from the University of Chicago in 1943. Upon graduation, he joined the United States Navy, where he served as a radar officer on multiple ships, including the USS Sangamon, the victim of a kamikaze attack on May 24, 1945. After earning a Juris Doctor from the University of Chicago Law School in 1949, he joined the law firm of Goldberg, Devoe & Brussell, which had become known as Shadur, Krupp & Miller by the time of Shadur's appointment to the federal judiciary, and is today known as Miller, Shakman & Beem. In addition to Shadur, the firm produced a number of other highly-regarded jurists, including former United States Supreme Court Justice Arthur Goldberg; Mikva, who served on the United States Court of Appeals for the District of Columbia Circuit and as White House Counsel; and United States District Court Judge Elaine E. Bucklo.
Passage 2:Apart from its engine configuration, the C.43 was conventional and shared its airframe with the three engined C.39. The first five engine aircraft built in France, it was a three bay biplane with fabric covered, rectangular plan wings mounted without stagger. The lower wing had dihedral outboard of the engines, reducing the large interwing gap from inboard to outboard. Though their spans were about equal (on the C.39, the upper span was and the lower one ) or 93% of the upper) the area of the lower wing was only 76% that of the upper because of a narrower chord. The wings were joined by vertical pairs of interplane struts, the forward members attached near the leading edges, and the centre section was supported by similar, shorter cabane struts from the upper fuselage. The inner bay was defined by two close pairs of interplane struts, which between them supported the push-pull pairs of Le Rhone 9C nine cylinder rotary engines about halfway between the wings. Each pair was mounted in a long, cylindrical cowling. Its ailerons, on the upper wing only, were aerodynamically balanced by overhanging extensions beyond the tips, as on the C.39.
