Meselson had been trying through the 1980s to answer the questions he first raised when studying the intelligence reports. An effort in 1983 to organize an expedition to Sverdlovsk fell apart after the Korean airliner shoot down that year. In 1986, he was invited to come to Moscow by officials at the Ministry of Health. On that visit, Meselson met with several top Soviet health officials, including Pyotr Burgasov, the deputy health minister who, at the time of the outbreak, spread the story that contaminated meat was the cause of the anthrax epidemic. Burgasov probably knew better; he had been involved with the Soviet biological weapons program since the 1950s and had served in the Sverdlovsk facility from 1958 to 1963. In the meetings in Moscow with Meselson, August 27– 30, 1986, Burgasov repeated that contaminated meat was the cause and added that contaminated bone meal had been fed to cattle and caused the epidemic. Meselson also met with Vladimir Nikiforov, chief of the infectious diseases department at the Central Postgraduate Institute, located within the Botkin Hospital in Moscow, and Olga Yampolskaya, a specialist in infectious diseases there, who had been present during the Sverdlovsk epidemic. Nikiforov was the courtly scientist who had courageously told the Sverdlovsk pathologists to hide and preserve their autopsy results in 1979. But now he was advancing the official line. Nikiforov showed Meselson fourteen photographic slides from the autopsies that, he insisted, supported the argument that anthrax had been ingested by eating the contaminated meat. The lungs of the victims, he claimed, were “undamaged and free of hemorrhage.” Before leaving Moscow on August 29, Meselson told the charge d’affaires at the U.S. Embassy what he found in his discussions. The Soviet officials had insisted victims had died from intestinal anthrax; Meselson said he had no way of knowing if the story was true, but it “did seem to hang together.”6
In September 1986, the Soviet officials offered the same false explanation in Geneva at the Second Review Conference for the Biological Weapons Convention. Soviet officials prepared a briefing for Gorbachev warning him that suspicions were deepening in the West that the Soviet Union had something to hide. Nonetheless, the cover-up continued at the conference and afterward.7 On October 10–12, 1986, Joshua Lederberg, president of Rockefeller University, who was chairman of the Committee on International Security and Arms Control of the National Academy of Sciences, visited Moscow. Lederberg was a pioneering microbiologist, recipient of the 1953 Nobel Prize for the discovery that bacteria engage in a form of sexual reproduction and thus possess a genetic mechanism similar to those of higher organisms. Lederberg was presented with the story that anthrax bacteria had been spread by contaminated meat from cattle fed a bonemeal supplement that was improperly sterilized, and produced from naturally infected carcasses. Like Meselson, Lederberg was deceived. “My personal conclusion,” Lederberg later wrote, “is that the present Soviet account of the epidemic is plausible on its face and internally consistent.” The Soviet explanations are “very likely to be true.”8
In Moscow, on November 18, 1986, the Central Committee and the Council of Ministers approved a measure, proposed by the Defense Ministry, to move the secret formulas for biological weapons and the manufacturing plants away from the military. Specifically, the measure called for action by 1992—in the course of the next six years—to eliminate “the stockpile of biological recipes and industrial capacities for production of biological weapons located at the sites of this ministry.” This appears to mean that over the next six years, the Defense Ministry would transfer the formulas and production facilities to the better-concealed Biopreparat complex. Such a move was already undertaken with the anthrax facility at Sverdlovsk, which was moved to Stepnogorsk. The reason for the move, according to the documents, was to meet the goal “of insuring openness of work in conditions of international verification.” This was code for the fact that Soviet leaders wanted to keep the program alive—and well hidden—at a time when international inspectors might be nosing around. It seems extremely likely that such a high-level action by the Central Committee, which was led by members of the Politburo, would have come to Gorbachev’s attention.9
In 1987, a fresh worry arose in Moscow among the top echelons of Biopreparat and the military. For all their efforts at secrecy, a speech on chemical weapons treaty verification by Foreign Minister Eduard Shevardnadze threatened to crack open the door to their empire. During Gorbachev’s
On October 2, 1987, after Shevardnadze’s speech, the Central Committee and Council of Ministers issued an order to speed up preparations for possible international inspections. The goal was not to be open, but the opposite: continue the secret germ warfare program by moving the formulas and factories to a more secret place. And do it quicker.11
The Sverdlovsk deception reached a new level of audacity April 10–17, 1988, when Burgasov, Nikiforov and a third Soviet medical official, Vladimir Sergiyev, came to the United States with a presentation of their theory about contaminated meat and bonemeal. Meselson said he arranged the visit in hopes that the Soviet officials would be exposed to expert questioning from American scientists. The Soviets delivered their bogus story to distinguished audiences three times: at the National Academy of Sciences in Washington, the Johns Hopkins School of Hygiene and Public Health in Baltimore and the American Academy of the Arts and Sciences in Cambridge, Massachusetts. “It was clear to us that infectious meat was the cause,” claimed Burgasov. “The whole idea of some sort of aerosol is impossible,” he said. He dismissed the possibility of a leak of anthrax bacteria from Compound 19. “I couldn’t imagine that in the midst of the highly populated area that there could be any work on highly dangerous pathogens,” he said, although he knew that was probably what happened. Nikiforov, who also knew the truth, narrated autopsy slides that portrayed great black intestinal sores, which pointed toward contaminated meat, not inhalation. In all, the Soviet officials had addressed more than two hundred private and government medical scientists and arms control experts, delivering untruths to all of them. Afterward, summarizing the Soviet presentations, Meselson wrote that he found the Soviet explanation “plausible and consistent with what is known from previous outbreaks of human and animal anthrax in the USSR and elsewhere, including the US.” Meselson still hoped to send a group of American scientists to Sverdlovsk.12
Alibek, who had built the anthrax assembly line at Stepnogorsk and was now working in Moscow at the Biopreparat headquarters, sensed the tension over possible international inspections. “Once knowledgeable foreign scientists set foot in one of our installations, our secret would be out,” he wrote in his memoir. When Alibek became first deputy director of Biopreparat in 1988, he was put in charge of hiding the evidence. The assignment soon crowded out his other duties. A special task force for the deception plans was set up at the Moscow Institute of Applied Biochemistry. Even the name of the institute was itself a deception. “The institute had no connection with biochemistry: its function was to design and manufacture equipment for our labs,” he said. The task force was given the equivalent of $400,000 to create a cover story, or “legend,” for Biopreparat operations and to demonstrate the “civilian” character of the work, that they were making medicines to defend against disease, or pesticides.
“Nevertheless, some of us worried that foreign inspectors would see through our schemes.” By 1988, Biopreparat had produced an instruction manual for employees on how to answer questions for inspectors, Alibek said. “Every conceivable question—What is this room for? Why is this equipment here?—was followed by a prepared reply, which workers were expected to memorize.”
“I was most concerned about our smallpox project,” he said. “If foreign inspectors brought the right equipment to the Vector compound in Siberia, they would immediately pick up evidence of smallpox.” As part of the global smallpox eradication effort, in which the Soviet Union had played a leading role, there were supposed to be
