Research Ethics Timeline

David B. Resnik, J.D., Ph.D., Bioethicist, NIEHS/NIH

Note: This list is the author’s own interpretation of some important events in the history of research ethics and does not include every event that some people might regard as important. I am open to suggestions for additions, revisions, etc.

  • 1620

    Francis Bacon publishes The Novum Organon, in which he argues that scientific research should benefit humanity.

  • 1632

    Galileo Galilea publishes his Dialogue on Two World Systems, in which he defends a heliocentric theory of the solar system, a view that contradicted the Catholic Church’s position that the Earth does not move but that the Sun moves around it. In 1633, Galileo appeared before an inquisitor from the Catholic Church. He was forced to recant his views and was sentenced to house arrest for the remainder of his life. The Church banned his book. In 1992, 359 years after Galileo’s arrest, Pope John Paul II formally apologized for its treatment of Galileo.

  • 1752

    The Royal Society of London institutes peer review procedures for articles submitted to The Philosophical Transactions of the Royal Society of London. The Philosophical Transactions, the world’s first scientific journal, was first published in 1665.

  • 1796

    Edward Jenner inoculates eight-year-old James Phipps with fluid from a cowpox pustule to immunize him against smallpox.

  • 1830

    Charles Babbage publishes Reflections on the Decline of Science in England, And Some of Its Causes, in which he argues that many of his colleagues were engaging in dishonest research practices, including fabricating, cooking, trimming, and fudging data.

  • 1856

    Charles Darwin and Alfred Wallace publish The Origin of Species, which proposes a theory of evolution of living things by natural selection. The book generates a great deal of controversy because it proposes that human beings were not created by God (as most religions claimed) but descended from apes. Darwin collected most of the data for the theory while serving as the ship’s naturalist on the voyage of the HMS Beagle (1831-1836). He waited over twenty years to publish his ideas because he knew they would meet with strong opposition and he wanted to ensure that he could back up his claims with evidence and arguments. George Lyell urged Darwin to publish his theory after reading a paper by Alfred Wallace that proposed a theory similar to Darwin’s, so that Darwin could establish precedence. Instead, Darwin shared credit with Wallace.

  • 1885

    Louis Pasteur administers an experimental rabies vaccine to nine-year-old Joseph Meister without testing it on animals first.

  • 1874

    Robert Bartholomew inserts electrodes into a hole in the skull of Mary Rafferty caused by a tumor. He notes that small amounts electric current caused bodily movements and that larger amounts caused pain. Rafferty, who was mentally ill, fell into a coma and died a few days after the experiment.

  • 1897

    Giuseppe Sanarelli injects the yellow fever bacteria into five patients without their consent. All the patients developed the disease and three died.

  • 1900

    Walter Reed experiments to determine the cause of yellow fever. Thirty-three participants, including eighteen Americans and six Cubans, were exposed to mosquitoes infected with yellow fever or injected with blood from yellow fever patients. Six participants died, including two researcher-volunteers. The participants all signed consent forms, some of which were translated into Spanish.

  • 1909

    Robert Millikan performs oil drop experiments to determine the charge of an electron. Millikan received a Nobel Prize for this research in 1923. Historians and journalists who studied Millikan’s notebooks discovered that he did not report 33 out of 149 oil drop observations that he had marked as “fair” or “poor.” Millikan also did not name his student, Harvey Fletcher, as an author on the paper that reported the results of these experiments, even though Fletcher made important contributions to the design of these experiments, such as suggesting that Millikan use oil droplets instead of water droplets.

  • 1912

    Museum curator Charles Dawson discovers a skull in at Piltdown gravel bed near Surrey, U.K. It was thought to be the fossilized remains of a species in between humans and apes (i.e. “a missing link”). A controversy surrounded the skull for decades and many scientists believed it to be fake. Chemical analyses performed in 1953 confirmed these suspicions by showing that the skull is a combination of a human skull and orangutan jaw, which had been treated with chemicals to make them appear old. The identity of the forger is still unknown, though most historians suspect Dawson.

  • 1925

    The University of Wisconsin establishes the Wisconsin Alumni Foundation (WARF), an independent organization that manages intellectual property (e.g. patents) and investments owned by the university and supports scientific innovation and discovery on campus. At that time, few universities owned or managed patents that were awarded to their researchers. WARF helps Harry Steenbock develop his invention for fortifying fats with vitamin D.

  • 1932-1972

    The Tuskegee Syphilis Study, sponsored by the U.S. Department of Health, Education and Welfare, begins in 1932. The study investigated the effects of untreated syphilis in 400 African American men from the Tuskegee, Alabama area. The researchers did not tell the subjects that they were in an experiment. Most subjects who attended the Tuskegee clinic thought they were getting treatment for "bad blood." Researchers withheld treatment for the disease from participants even when penicillin, an effective form of treatment, became widely available in the 1950s. The study ended in 1972, after a news story from the Associated Press alerted the public and Congress to the ethical problems with the research. The U.S. government settled a lawsuit brought by the participants and their families.

  • 1932-1945

    Japanese scientists working at Unit 731 performed morally abominable experiments on thousands of Chinese prisoners or war, including biological and chemical weapons experiments, vaccination experiments, and wound-healing and surgical studies, including vivisections. The U.S. government agreed to not prosecute the scientists for war crimes in exchange for data from the biological and chemical weapons research. Unit 731 of the Imperial Japanese Army also conducted research on Korean prisoners/civilians (such as Dong Ju Yoon (arguably the most famous modern era Korean poet) and Chung-Chun Lee (a Korean national hero and freedom fighter)), as well as Mongolians, Manchurians (separate from Chinese), and Russians.

  • 1939-45

    German scientists conducted morally abominable research on concentration camp prisoners, including experiments that exposed subjects to freezing temperatures, low air pressures, ionizing radiation and electricity, and infectious diseases; as well as wound-healing and surgical studies. The Allies prosecuted the German scientists for war crimes in the Nuremberg Trials. The Nuremberg Code provided the legal basis for prosecuting the scientists.

  • 1940

    Two German refugee scientists, Frisch and R.E. Peierls, warn the U.S. about Germany's nuclear weapons program. Albert Einstein sends a letter to President Roosevelt warning him about the threat posed by Germany. The letter, which was written by Leó Szilárd in consultation with Edward Teller and Eugene Wigner, was signed by Einstein. The letter suggested that the U.S. should develop a nuclear weapons program.

  • 1942-1945

    The U.S. conducts the $2 billion Manhattan Project to develop an atomic bomb. General Leslie Groves direct the Project and physicist Robert Oppenheimer oversees the scientific work.

  • 1944-1980s

    The U.S. Department of Energy sponsors secret research on the effects of radiation on human beings. Subjects were not told that they were participating in the experiments. Experiments were conducted on cancer patients, pregnant women, and military personnel.

  • 1945

    The U.S. drops atomic bombs on Hiroshima and Nagasaki, Japan, killing an estimated 200,000 civilians.

  • 1945

    Led by President Eisenhower and atomic bomb scientist Robert Oppenheimer, the "atoms for peace" movement begins.

  • 1945

    Vannevar Bush writes the report Science: The Endless Frontier for President Roosevelt. The report argues for a major increase in government spending on science and defends the ideal of a self-governing scientific community free from significant public oversight. It advocates for investment in science and technology as a means of promoting national security and economic development.

  • 1947

    The Nuremberg Code, the first international code of ethics for research on human subjects, is adopted.

    Norbert Wiener, the founder of cybernetics, published an article in the Atlantic Monthly titled "A Scientist Rebels" in which he refuses to conduct research for the military.

  • 1948

    Alfred Kinsey publishes Sexual Behavior in the Human Male. Five years later, he publishes Sexual Behavior in the Human Female. These books were very controversial, because they examined topics which were regarded as taboo at the time, such as masturbation, orgasm, intercourse, promiscuity, and sexual fantasies. Kinsey could not obtain public funding for the research, so he funded it privately through the Kinsey Institute.

  • 1949

    The Soviet Union tests an atomic bomb; the Cold War begins.

  • 1953

    James Watson and Francis Crick propose a model for the structure of DNA, for which they eventually would share the Nobel Prize in 1962. They secretly obtained key x-ray diffraction data from Rosalind Franklin without her permission. Franklin was not named as an author on Watson and Crick’s paper. She was not awarded a Nobel Prize because she died in 1953 from ovarian cancer (at age 37), and the prize is not awarded posthumously.

  • 1956-1980

    Saul Krugman, Joan Giles and other researchers conduct hepatitis experiments on mentally disabled children at The Willowbrook State School. They intentionally infected subjects with the disease and observed its natural progression. The experiments were approved by the New York Department of Health.

  • 1950s-1963

    The CIA begins a mind control research program, which includes administering LSD and other drugs to unwitting subjects.

  • 1957

    The Soviets launch Sputnik, the first satellite, which triggers the U.S. government to increase its investments in science and technology to avoid falling behind in the space race.

  • 1957-1962

    In 1957, thalidomide is marketed in West Germany as medication to treat morning sickness during pregnancy. About 10,000 infants, mostly in West Germany, are born with severe birth defects as a result of exposure to this drug. 2,000 children die from thalidomide exposure. In 1960, Frances Kathleen Oldham Kelsey, a drug reviewer for the FDA, refused to approve the drug. Soon, countries around the world ban the drug. Kelsey is awarded the President's Award for Distinguished Federal Civilian Service in 1962.

  • 1961

    President John F. Kennedy commits the U.S. to the goal of putting a man on the moon by the end of the decade.

    Rachel Carson publishes Silent Spring, which alerts people to the harmful effects on the environment of various toxins and pollutants, including DDT. Her book launches the environmentalist movement.

  • 1961-1962

    Stanley Milgram conducts his "electric shock" experiments, which proved that people are willing to do things that they consider to be morally wrong when following the orders of an authority. The experiments, which had several variations, included a learner, a teacher, and a researcher. The learner was connected to electrodes. If the learner gave an incorrect response to a question, the researcher would instruct the teacher to push a button on a machine to give the learner an electric shock. Teachers were willing to do this even when the dial on the machine was turned up to “dangerous” levels and the learner were crying out in pain and asking for the experiments to stop. In reality, no shocks were given. The purpose of the experiments was to test subjects’ willingness to obey an authority figure. Since then, other researchers who have repeated these experiments have obtained similar results.

  • 1964

    The World Medical Association publishes Declaration at Helsinki, Ethical Principles for Research Involving Human Subjects. The Helsinki Declaration has been revised numerous times, most recently in 2013.

    Henry Beecher publishes an article in the New England Journal of Medicine alerting scientists and doctors to 22 unethical studies, including the Tuskegee syphilis study and the Willowbrook hepatitis study.

  • 1960s/1970s

    The animal rights movement impacts scientific research. The U.S. Public Health Service publishes its Guide for the Humane Care and Use of Laboratory Animals in 1963. The Guide requires research institutions to form Institutional Animal Care and Use Committees (IACUCs) to review and oversee animal experiments. The U.S. Congress adopts the Animal Welfare Act in 1966, which protect animals used in research, excluding rodents and birds. Various states adopt or revise animal cruelty laws, which also protect animals used in research. In 1975, Peter Singer publishes Animal Liberation, which provides a philosophical defense of the animal rights movement. Singer argues that most animal research is immoral.

  • 1969

    The U.S. lands the first man on the moon.

  • 1973

    After conducting hearings on unethical research involving human subjects, including the Tuskegee study, Congress passes the National Research Act in 1973, which President Nixon signs in 1974.

    Margot O'Toole, a post-doctoral student at the Whitehead Institute, has some questions about data in a paper authored by six of her colleagues and published in the journal Cell in 1986. She asks to examine Thereza-Imanishi-Kari's lab notebooks, which seem to be inconsistent with published results. She accuses Imanishi-Kari of fabricating and falsifying data. The ensuing investigation leads to inquiries by MIT and Tufts as well as the NIH and a Congressional committee chaired by Rep. John Dingell. Nobel Prize winner David Baltimore is one of the co-authors on the disputed paper. Although he was not accused of misconduct, Baltimore resigns as President of Rockefeller University. He described the investigation, which was covered by the New York Times, as a "witch hunt." An appeals board at the DHHS eventually exonerated Imanishi-Kari, who admitted only to poor record keeping.

Most courts have followed this ruling by holding that patients no longer have rights to tissues leftover from surgeries or procedures or donated to researchers.

  • 1990

    Congress investigates conflicts of interest involving Pharmatec and the University of Florida.

  • 1990s-present

The EPA revised its human subjects rules in response to a Congressional mandate to strengthen protections for children and pregnant or nursing women.

  • 2004

    Ronald Reagan, Jr. makes a presentation in support of federal funding for embryonic stem cell research to the Democratic Convention. Stem cell research (and therapeutic cloning) become hot issues in the 2004 Presidential election.

  • 2004

    Merck withdraws its drug Vioxx from the market, due to safety and liability issues. As many as 50,000 people had a heart attack or stroke while take the drug, and thousands sued the company. As early as 2001, Merck scientists suspected that Vioxx could increase the cardiovascular risks, but researchers funded by Merck did not publish some of the data that would support these suspicions, even though they reported it to the FDA. In 2001, the FDA warned Merck that it had misrepresented Vioxx’s safety profile to the public and in 2002 it issued a black box warning for the drug. A systematic review of antidepressant medications known as selective serotonin uptake inhibitors (SSRIs) found that some of these drugs increase the risks of suicide in adolescents and children. The review included data from the U.K.’s Committee on Safety in Medicines, which had not been previously published. Patients, parents, researchers, and policymakers accused companies intentionally hiding this data from the public, and New York Attorney General Eliot Spitzer sued Glaxo for fraud. As a result of these problems related to data suppression, government agencies (including the FDA) and journals now require clinical trials to be registered on a publicly available website. Registration includes important information about the studies, including research design, interventions, and methods; research sites and personnel; contact information; and research results (but not raw data).

  • 2005

    In response to criticism from Congress, the NIH revises its conflict of interest rules for intramural research. NIH researchers cannot hold stock in pharmaceutical or biotech companies or consult with these companies for pay.

    Someone hacked into the email server at the University of East Anglia Climatic Research Unit (CRU) and posted on the internet thousands of emails exchanged between climate change researchers at the CRU and researchers around the world. The emails showed that the researchers refused to share data and computer codes with climate change skeptics, who called the incident "climategate." The Intergovernmental Panel on Climate Change (IPCC), which relies heavily on data and models from CRU researchers, vowed to promote greater openness in climate research.

    While doing research on the Tuskegee Syphilis Study, Susan Reverby, Professor of Women’s Studies at Wellesley College, uncovered documents concerning unethical research experiments on human subjects conducted by the U.S. government in Guatemala from 1946 to 1948. The research involved intentionally infecting over 1300 subjects with syphilis to test the effectiveness of penicillin in preventing this disease. Only 700 subjects were given penicillin and 83 died as a result of the study. The subjects were not informed that they were participating in an experiment.

    Lancet retracts a paper for fraud, published in 1998 by Andrew Wakefield and colleagues, linking autism to vaccine for measles, mumps, and rubella. Members of the anti-vaccine movement cited the paper as proof that childhood immunizations are dangerous. Vaccination rates in U.K., Europe, and the U.S. declined after Wakefield’s study was published. An investigation by journalist Brian Deer found that Wakefield had not disclosed a significant financial interest and had not obtained ethics board approval for the study. Wakefield’s research had been supported by a law firm that was suing vaccine manufacturers. A lawyer for the firm had helped Wakefield recruit patients. Wakefield did not disclose his relationship to the law firm in the 1998 paper. In 2010, the U.K.’s General Medical Council (GMC) revoked Wakefield’s license to practice medicine following an investigation which concluded that he had not disclosed a significant financial interest and had performed risky procedures, such as colonoscopies and lumbar punctures, without appropriate pediatric qualifications or ethics committee approval.

    Journalist Rebecca Skloot publishes a widely-acclaimed book about Henrietta Lacks, an African American woman who provided the tissue for a widely-used cell line known as HeLa (an abbreviation of her name). In 1951, Lacks underwent treatment for cervical cancer at Johns Hopkins Hospital and died later that year. Researchers discovered that they were able to culture the cells from Lacks’ tumor and keep them alive, which was the first time that scientists had been able to grow a human cell line. HeLa cells have been used in thousands of laboratories around the world in various biomedical experiments. Skloot was interested in finding out where the HeLa cell line came from, and she discovered that it came from Henrietta Lacks. Skloot interviewed Lacks’ family and learned that researchers had grown her tumor cells without her consent and without providing the family any compensation, which was a common practice at that time. Skloot decided to share profits from her book with the family. In 2013, the NIH reached an agreement with Lacks’ family concerning access to genomic data from the cell line. The agreement gives the family control over access to the data and acknowledgment in scientific papers. In 2021, the Lacks family sued Thermo Fisher Scientific, a company that commercialized them the cell line. The lawsuit claims that the company unjustly profited from Lacks' tissue without her consent.

    Two papers embroiled in controversy were published in Science and Nature after several months of debate about their implications for bioterrorism. The papers reported results of NIH-sponsored research conducted by a team working in the Netherlands, led by Ron Fouchier, and a team working at the University of Wisconsin, led by Yoshihiro Kawaoka. The researchers were able to genetically modify an H5N1 avian flu virus so that it can be transmitted by air between mammals, including humans. Currently, avian flu can only be contracted through direct contact with birds. The virus is highly lethal, with a mortality rate of over 50%. Over 300 people have died from the virus since 1997. The National Science Advisory Board for Biosecurity (NSABB) initially recommend that the papers be published in redacted form, with key details removed and only made available to responsible scientists, so the terrorists or others could not use the information to make deadly bioweapons. However, the NSABB changed its mind and recommended full publication of both papers after learning more about the value of the research for public health (e.g. monitoring of bird populations, vaccine development), biosafety measures, how difficult it would be for terrorists to replicate the work, and problems with redacted publication.

    In Association for Molecular Pathology et al. v. Myriad Genetics, the U.S. Supreme Court rules that isolated and purified DNA cannot be patented. Only DNA that has been modified by human beings can be patented. The ruling invalidates Myriad’s patents on BRCA1 and BRCA2 genes and creates uncertainty concerning the legal validity of other types of patents on isolated and purified chemicals.

    Haruko Obokata, a biochemist at the RIKEN Center for Developmental Biology in Kobe, Japan, and coauthors published two high-profile papers in Nature describing a method for converting adult spleen cells in mice into pluripotent stem cells by means of chemical stimulation and physical stress. Several weeks after the papers were published, researchers at the RIKEN Center were unable to reproduce the results and they accused Obokata, who was the lead author on the papers, of misconduct. The journal retracted both papers in July after an investigation by the RIKEN center found that Obokata had fabricated and falsified data. Later that year, Obokata’s advisor, Yoshiki Sasai, committed suicide by hanging himself.

    During the COVID-19 pandemic, which killed millions of people around the world, scientists worked feverishly to conduct research that could help combat this public health crisis. To make data and results available as quickly as possible, many journals expedited their peer review process for COVID-19 submissions and scientists published articles on pre-print servers before undergoing peer review. Unfortunately, the rush to publish led to the dissemination of invalid, irreproducible, and falsified results in some cases. Dozens of COVID-19 papers had to be retracted or withdrawn. Two prominent biomedical journals, the New England Journal of Medicine and the Lancet, retracted papers after the editors learned that the healthcare analytics company Surgisphere, which provided the data used in the studies, was not making the raw data available to independent scientists who found inconsistencies in the data and wanted to do an audit. The journals also learned that Surgisphere did not make all the data available to the scientists who authored the papers.

    In early 2020, at the beginning of the COVID-19 pandemic, US scientists claimed that the SARS-CoV-2 virus that causes the disease probably moved from horseshoe bats into the human population via an undetermined intermediate host species. Others believed that SARS-CoV-2 was a genetically engineered pathogen that had escaped from a laboratory at the Wuhan Institute of Virology (WIV) in China. The World Health Organization attempted to investigate the origins of the virus by interviewing scientists at WIV and inspecting facilities, but they were unable to obtain all the information they needed. During 2020, there was a scientific consensus that SARS-CoV-2 probably had a natural origin. Opinions began to change in 2021, however, when highly respected science writer Nicholas Wade published several articles critically examining the two competing hypotheses: natural origin vs. laboratory escape. Wade argued that there was substantial evidence supporting the laboratory escape hypothesis, because an intermediate host species had not been found despite intense searching and a key part the protein that the virus uses to infect cells, known as the furin cleavage site, does not occur in related coronaviruses. After Wade’s articles were published, many scientists started publishing papers examining evidence concerning the origins of SARS-CoV-2. However, the origins of SARS-CoV-2 remain a mystery.
