During the late
1980s and early
1990s,
Thereza Imanishi-Kari, a scientist who was not in
Baltimore's laboratory but in a separate, independent laboratory at
MIT, was implicated in a case of scientific fraud. The case received extensive news coverage and a Congressional investigation. The case was linked to Baltimore's name because of his scientific collaboration with and later his strong defense of Imanishi-Kari against accusations of fraud.
In
1986, while a
Professor of
Biology at MIT and
Director at
Whitehead, Baltimore co-authored a scientific paper on immunology with Thereza Imanishi-Kari (an
Assistant Professor of Biology who had her own laboratory at MIT) as well as four others.[57] A postdoctoral fellow in Imanishi-Kari's laboratory, Margot
O'Toole, who was not an author, reported concerns about the paper, ultimately accusing Imanishi-Kari of fabricating data in a cover-up. Baltimore, however, refused to retract the paper.
O'Toole soon dropped her challenge, but the
NIH, which had funded the contested paper's research, began investigating, thanks to the insistence of
Walter W. Stewart, a self-appointed fraud buster, and Ned
Feder, his lab head at the NIH.[58]
Representative John Dingell (
D-MI) also aggressively pursued it, eventually calling in
U.S. Secret Service (
USSS;
U.S. Treasury) document examiners.[59]
Around October 1989, when Baltimore was appointed president of
Rockefeller University, around a third of the faculty opposed his appointment because of concerns about his behaviour in the Imanishi-Kari case. He had to visit every laboratory, one by one, to hear those concerns directly from each group of researchers.[58]
In a draft report dated March 14,
1991 and based mainly on USSS forensics findings, NIH's fraud unit, then called the
Office of Scientific Integrity (
OSI), accused Imanishi-Kari of falsifying and fabricating data. It also criticized Baltimore for failing to embrace
O'Toole's challenge.[citation needed]
Less than a week later, the report was leaked to the press.[60] Baltimore and three co-authors then retracted the paper; Imanishi-Kari and
Moema H.
Reis did not
sign the retraction.[61] In the report, Baltimore admitted that he was "too willing to accept" Imanishi-Kari's explanations, and felt he "did too little to seek an independent verification of her data and conclusions."[62] Baltimore publicly apologized for not taking a whistle-blower's charge seriously.[63]
Amid concerns raised by negative publicity in connection with the scandal, Baltimore resigned as president of Rockefeller University[64] and rejoined the MIT Biology faculty.[65]
In July
1992, the
US Attorney for the
District of MD, who had been investigating the case, announced he would bring neither criminal nor civil charges against Imanishi-Kari.[66][67] In
October 1994, however, OSI's successor, the
Office of Research Integrity (
ORI;
HHS) found Imanishi-Kari guilty on 19 counts of research misconduct, basing its conclusions largely on Secret Service analysis of laboratory notebooks.
An HHS appeals panel began meeting in June
1995 to review all charges in detail. In June
1996, the panel ruled that the ORI had failed to prove even one of its 19 charges. After throwing out much of the documentary evidence gathered by the ORI, the panel dismissed all charges against Imanishi-Kari. As their final report stated, the HHS panel "found that much of what ORI presented was irrelevant, had limited probative value, was internally inconsistent, lacked reliability or foundation, was not credible or not corroborated, or was based on unwarranted assumptions." It did conclude that "
The Cell paper as a whole is rife with errors of all sorts
... [including] some which, despite all these years and layers of review, have never previously been pointed out or corrected.
Responsibility ... must be shared by all participants." Neither OSI nor ORI ever accused Baltimore of research misconduct.[68][69] The reputations of
Stewart and Feder, who had pushed for the investigation, were very damaged.[69]
Baltimore has been both defended and criticized for his actions in this matter. In
1993,
Yale University mathematician
Serge Lang strongly criticized Baltimore's behavior.
Historian of science Daniel Kevles, writing after the exoneration of Imanishi-Kari, recounted the affair in his
1998 book,
The Baltimore Case.
Horace Freeland Judson also gives a critical assessment of Baltimore's actions in
The Great Betrayal:
Fraud In
Science. Baltimore has also written his own analysis.
