David Baltimore (b. March 7, 1938) is an American biologist and co-recipient of the 1975 Nobel Prize in Physiology or Medicine. He is currently the Robert A.

Baltimore was born in New York City and graduated from Swarthmore College (BA, 1960). He received his Ph.D. at Rockefeller University in 1964. At the age of 37, while on the Massachusetts Institute of Technology (MIT) faculty, he shared the Nobel Prize with Howard Temin for the discovery of reverse transcriptase (RTase). Baltimore and Temin worked independently of each other yet discovered RTase at the same time [1]. Since RTase transcribes RNA into DNA, this work upset a central dogma of molecular biology: that DNA led to RNA, which in turn led solely to proteins.

Imanishi-Kari Case

For most people outside of science, Baltimore is best known for his role in an affair of alleged scientific misconduct. In 1986, Professor of Biology, MIT & Director, Whitehead Institute Baltimore co-authored a scientific paper on immunology with Assistant Professor of Biology, MIT Thereza Imanishi-Kari and four others. [2] A postdoctoral fellow in Imanishi-Kari's laboratory, Dr. Margot O'Toole, who was not an author, could not reproduce some of the experiments in the paper and discovered laboratory data that contradicted the published data. O'Toole then challenged the authors to explain the discrepancies and ultimately accused Imanishi-Kari of fabricating data in a cover-up. Baltimore initially refused to retract the paper, although he did later with three co-authors (Imanishi-Kari and Moema H. Reis did not sign the retraction).[3] Although O'Toole soon dropped her challenge, Walter W. Stewart and Ned Feder, National Institutes of Health (NIH; Health & Human Services (HHS), U.S. Federal Government) scientists, picked it up. Because they and the authors also could not resolve the challenge, NIH, which had funded the contested paper's research, began investigating. It was then also taken up in the United States Congress by Representative John Dingell (D-MI) who aggressively pursued it, eventually calling in US Secret Service (USSS; US Treasury) document examiners. The House of Representatives' Subcommittee on Oversight & Investigations of the Committee on Energy & Commerce, chaired by Mr. Dingell, held four hearings analyzing the case.[4] In a draft report dated 14 March 1991 and based mainly on USSS forensics findings, NIH's fraud unit, then called the Office of Scientific Integrity (OSI), accused Dr. Imanishi-Kari of falsifying and fabricating data. It also harshly criticized Baltimore for failing to embrace O'Toole's challenge. After the report was soon leaked to the press, Baltimore stated he would retract the paper.[5] Scientific misconduct is the violation of the standard codes of scholarly conduct and ethical behavior in professional scientific research. ...

During the ensuing controversy/uproar (including extensive press coverage) the Rockefeller University faculty pressured President Baltimore to resign December 1991, after only 1.5 years in the office (term began 1 July 1990). An extensive file/analysis of the case assembled by Yale University mathematician Serge Lang entitled, "Questions of Scientific Responsibility: The Baltimore Case" was published in the journal, Ethics & Behavior Spring 1993. 26 October 1994 OSI's successor, the Office of Research Integrity (ORI, HHS) reviewed the case and found Imanishi-Kari guilty on 19 counts of research misconduct; it recommended she be barred from receiving HHS research grants for 10 years. In June 1996, a HHS appeals panel reviewed the case again and dismissed all charges. Neither OSI nor ORI ever accused Baltimore of research misconduct. Baltimore has been both admired for defending a junior faculty member at great personal and professional cost and criticized for failing to be a responsible scientist. Daniel Kevles' book, The Baltimore Case: A Trial of Politics, Science, and Character recounts the affair but is sympathetic to Baltimore and Imanishi-Kari. For a different perspective, see Lang's study (also reprinted updated in his book, Challenges (New York: Springer-Verlag; 1997)) and/or Horace Freeland Judson's book, The Great Betrayal: Fraud in Science (Orlando: Harcourt; 2004).

van Parijs Case

Probably scientific fraud cost Baltimore the CalTech presidency as well.[dubious ] Image File history File links Wikitext. ...

3 October 2005 Baltimore resigned CalTech's presidency (reported by Los Angeles Times [6] ONLY) for not very specific reasons (same LA Times article). 6 October 2005 CalTech began an inquiry (Harvard Crimson [7]) that was prompted by a free-lance reporter's queries (NewScientist.com, "MIT professor sacked for fabricating data" [8]). The reporter had found suspicious data in several of Dr. Luk van Parijs' research papers, including one co-authored by, among others, Baltimore when van Parijs was a postdoctoral trainee of his at CalTech. 27 October 2005 MIT fired van Parijs, Associate Professor of Biology, claiming he, "[...A]dmitted to fabricating and falsifying research data in a paper and several manuscripts and grant applications" (MIT statement [9]). Luk Van Parijs was an associate professor of biology in Massachusetts Institute of Technologys Center for Cancer Research. ...

28 October 2005 the media storm began: NewScientist.com, Boston Globe[10], New York Times[11], The Tech[12], Harvard Crimson, TheScientist.com[13], Nature[14], Science[15], Chronicle of Higher Education[16], and Nature Immunology[17]; but not LA Times and none mentions Baltimore's resignation. Apparently, van Parijs' lab's members observed questionable scientific practices on his part and then reported to MIT authorities. MIT began investigating August 2004. The NewScientist.com and Science reports conflict whether MIT had reimbursed NIH. The news reports also point to suspicious data in two papers co-authored by van Parijs during his Harvard doctoral training. Harvard University is a private university in Cambridge, Massachusetts, USA, and a member of the Ivy League. ...

26 January 2006 a story [18] in Nature by the same free-lance reporter discusses suspicious data in two patent applications filed by Baltimore and van Parijs.

Other than retraction of falsified or fabricated data from one of van Parijs' papers [19] by co-authors online 14 May 2007 and in print [20], there has been no more news since from CalTech, Harvard, MIT, or ORI (as of 4 August 2007).
