Harold H. Greene (1924-2000) was a federal judge for the United States District Court for the District of Columbia. He was nominated by President Jimmy Carter in 1978. He presided over the antitrust suit that broke up the AT&T vertical market monopoly on the telecommunications industry in the United States. The case, one of Greene’s first after being named to the bench, resulted in the 1982 consent decree between AT&T and the Federal Trade Commission. The consent decree, later amended and usually called the modified final judgment (MFJ), provided for the spinoff of the regional bell operating companies (RBOCs). The conclusion of the case freed AT&T to enter the computer industry, from which it had previously been barred, leading to commercial distribution of the UNIX operating system. He received his law degree from The George Washington University Law School in 1952.
