Flexner worked late nights for the duration of his career, and with good reason. In 12 years with DOJ’s Antitrust Division, where he rose to become deputy assistant attorney general and acting head, he oversaw major litigation such as United States v. AT&T, which ultimately led to the breakup of the telephone giant in 1984.
