“Cohen’s thesis is that Yeltsin, rather than Russia’s first democratic leader, was a neo-czarist bumbler who destroyed a democratization process that, in fact, should be credited to Mikhail Gorbachev,” Robert D. Kaplan wrote in a Times review. “Cohen is particularly scathing toward American journalists, whom he depicts as overly influenced by the prosperity of a small, rapacious upper class in the major Russian cities, and who seldom ventured out into the countryside to see the terrible price of the reformers’ handiwork.”
Stephen Frand Cohen was born in Indianapolis on Nov. 25, 1938, the older of two children of Marvin and Ruth (Frand) Cohen. His father owned a jewelry store and a golf course in Hollywood, Fla. Stephen and his sister, Judith, attended schools in Owensboro, Ky., but Stephen graduated in 1956 from the Pine Crest School, a private school in Fort Lauderdale, Fla.
He loved the novels of Hemingway. As an undergraduate at Indiana University, he went to England on a study-abroad program. He had saved $300 for a side trip to Pamplona to run with the bulls. But an advertisement he saw for a 30-day, $300 trip to the U.S.S.R. changed his life.
Back at Indiana University, he gave up plans to be a golf pro and took up Russian studies. He earned a bachelor’s degree in economics and public policy in 1960 and a master’s in Russian studies in 1962. In 1969, he received a doctorate in that subject from Columbia University.
Professor Cohen’s marriage in 1962 to the opera singer Lynn Blair ended in divorce. He married Ms. vanden Heuvel in 1988. In addition to her, he is survived by a son, Andrew, and a daughter, Alexandra Cohen, from his first marriage; another daughter, Nicola Cohen, from his second marriage; a sister, Judith Lefkowitz; and four grandchildren.
His Columbia dissertation on Mr. Bukharin’s economic ideas grew into his first book, copies of which reached Soviet dissidents, the K.G.B. in Moscow, and eventually Mr. Gorbachev, who put Professor Cohen on his guest list for the 1987 Gorbachev-Reagan summit in Washington.
Professor Cohen taught at Princeton from 1968 to 1998, rising to full professor of politics and Russian studies, and at New York University thereafter until his retirement in 2011. His last book, published in 2019, was “War With Russia? From Putin & Ukraine to Trump & Russiagate.”
