Campaign Updates

Harvard University experimenter Margaret Livingstone tears baby monkeys away from their mothers shortly after birth and imprisons them in cold steel cages, where they’re given only a pathetic cloth “surrogate” to cling to for comfort. She’s sewn some of the babies’ eyes shut, leaving them in complete darkness for up to a year. Help end her morally depraved experiments.

First Baby Monkey Torture, Now Alleged Research Misconduct: Is Harvard’s Moral Compass Shattered?

February 2, 2024

Harvard Medical School’s abysmal reputation for abusing animals in deadly experiments, already cemented by veteran baby monkey torturer Margaret Livingstone, has been further solidified following back-to-back allegations that five Harvard professors manipulated data in dozens of published papers. The experimenters injected their animal victims with toxins, caused animals to grow tumors, and killed and dissected them. Read more.

January 24, 2024

PETA supporters wearing monkey masks rallied outside the office of Harvard University’s president while “experimenters” in lab coats tormented them with flashing strobe lights in a bizarre scene mimicking Harvard experimenter Margaret Livingstone’s latest cruel test.

PETA also urged former President Barack Obama to condemn Livingstone’s twisted experiments, for which she’s received more than $2 million in taxpayer funds from the National Institutes of Health’s BRAIN Initiative. The initiative was launched during the Obama administration.

August 23, 2023

PETA has filed a complaint with the National Institutes of Health (NIH), urging it to withdraw funding from Harvard University after the U.S. Department of Agriculture cited Harvard Medical School for violations of the federal Animal Welfare Act. Experimenters overdosed a monkey with a compound and couldn’t even manage to properly monitor the health of monkeys who were purposely being kept thirsty to force their cooperation in experiments. These callous episodes of neglect took place under the same roof where Margaret Livingstone runs her NIH-funded cruel and pointless sensory deprivation experiments on baby monkeys.

Dressed to Kill: PETA Urges Experimenter to Spare Monkeys With Special Birthday Teelivery

April 3, 2023

Will Harvard Medical School’s Margaret Livingstone give monkeys the gift of liberation for her birthday this year? PETA’s stylish surprise for the animal experimenter—a T-shirt in Harvard crimson along with a card offering to help place the monkeys in her laboratory with reputable sanctuaries—encourages her to hang up her welding mask and try on the garb of a former experimenter instead.

Monkey Tormenter Margaret Livingstone ‘Can’t Imagine Having More Fun Doing Anything Else’

November 17, 2022

How do you know if someone is an animal exploiter? Don’t worry—they’ll tell you. Prolific baby monkey torturer Margaret Livingstone does just that in her chapter of The History of Neuroscience in Autobiography, volume 9, a series that collects the stories of neuroscientists in their own words. Displaying not an ounce of remorse or self-awareness, she regales readers with (shock-)inspiring anecdotes about paralyzing lobsters with chemicals, devising her own torture device to deprive cats of sleep, and more. “I spend a lot of time now taking care of baby monkeys while wearing a mask so they never see any faces, and I can’t imagine having more fun doing anything else,” she writes.

One Monkey Dies, Another Loses Finger in Margaret Livingstone’s Lawless Laboratory

November 10, 2022

Given her habit of separating vulnerable infants from their bereft mothers, we already knew that Margaret Livingstone had a penchant for psychologically breaking monkeys. Now we know what else she has a penchant for breaking: the law. Federal reports obtained by PETA reveal that because of violations of federal animal welfare regulations in two separate instances, one monkey strangled to death and another sustained injuries so severe that the animal’s finger had to be amputated. Livingstone’s laboratory also earned a write-up from the feds after she failed to wear necessary personal protective equipment while experimenting on a restrained monkey, the documents show.

October 28, 2022

The most stomach-churning evil can be rationalized, normalized, and even claimed to be necessary, writes animal rights activist Wayne Hsiung—but it can be challenged with compassion. Hsiung, the founder of animal rights group Direct Action Everywhere, calls out the factual and ethical leaps in Harvard University’s statement in support of Margaret Livingstone and highlights the story of his mother, who understood that barbaric experiments like Livingstone’s were wrong despite suffering from the same terminal illness that Livingstone implausibly claims she’s helping to cure.

October 12, 2022

Roe detailed her concerns in a letter to Harvard University President Lawrence Bacow and other school officials, urging them to revoke university approval for the psychologically devastating tests. “It’s deeply concerning that experiments that induce irreversible harm on infant primates are permitted at Harvard Medical School at all, let alone allowed to occur for several decades,” she wrote.
