Donald F. Turner was a notable antitrust attorney and professor at Harvard Law School. He headed antitrust division at the United States Department of Justice under Lyndon Baines Johnson. He clerked for Supreme Court Associate Justice Tom Clark. He died in 1994 from Alzheimer's disease.
Upon his death, Associate Justice Stephen G. Breyer wrote his obituary on his legal career. (Volume 41, Antitrust Bulletin, pages 725-727 (1996)) Breyer wrote that Turner was Breyer's first post-clerkship employer.
He is celebrated for his 1956 article on the so-called Cellophane Case against the duPont company (Harvard Law Review Volume 70, No. 2 Dec 1956 pp. 281-318). It marked the first time economic analysis was well publicized to analyse antitrust law for the non-economist public.
