Robert E. Cornish: The Doctor Who 'Revived' Dead Dogs
Updated: Sep 4
In May 1934, in a laboratory near Berkeley, a biologist named Robert Cornish killed five fox terriers, all of them named Lazarus, and then tried to bring them back to life on a giant mechanical see-saw. Three of them stayed dead. Two didn't. Within a few years Cornish would be lobbying the state of California for permission to try the same trick on an executed murderer, playing himself in a Hollywood film built around his own experiments, and eventually settling into a rather quieter retirement selling toothpaste.
Quick Answers
● Who was Robert E. Cornish? An American biologist, born in 1903, best known for a series of 1930s experiments in which he attempted to resuscitate clinically dead dogs using a mechanical see-saw device and chemical injections.
● Did his experiments actually work? Partially. Two of his test dogs, named Lazarus IV and Lazarus V, were successfully revived after being clinically killed, though both were left blind and physically impaired.
● Did he ever try it on a human? He tried to. A death row inmate at San Quentin offered his body for the experiment, but California authorities refused Cornish permission to carry it out.
● What happened to Cornish afterward? His scientific career declined through the 1940s and 1950s. He later sold a commercial toothpaste and died in 1963 at 59.
A Genuine Child Prodigy
Robert Edwin Cornish was born on 21 December 1903 in San Francisco. By most accounts he really was exceptionally gifted: he finished high school at 15, graduated from the University of California, Berkeley at 18, and was licensed to practise medicine by 21. He completed his doctorate by 22 and returned to Berkeley as a researcher in his mid-twenties, working on an assortment of projects that included special lenses designed to let people read newspapers underwater.
None of that early, conventional promise hinted at what came next.
The Teeterboard
In 1932, Cornish became convinced that death, at least in its earliest moments, might be reversible. His method centred on a large teeterboard, essentially an oversized see-saw, onto which a body could be strapped and rocked rhythmically to simulate the pumping action of a heart. While the board rocked, Cornish injected a mixture of adrenaline and anticoagulants, hoping the combination of mechanical circulation and chemical stimulation might restart a body that had recently stopped.
His first trials, in 1933, targeted human victims of heart attacks, drowning and electrocution. None worked. Rather than abandon the idea, Cornish concluded he needed a more controlled test subject, and turned to dogs.
The Lazarus Dogs
Cornish's dogs, all fox terriers, were killed with a nitrogen gas mixture and left clinically dead for six to ten minutes before any revival attempt began, giving him a level of control over the exact circumstances of death that no human trial could offer. Each was then strapped to the teeterboard and given his adrenaline, heparin and oxygenated saline mixture, sometimes cut with defibrinated canine blood, blood with the natural clotting agent removed.
The first three dogs he revived this way didn't stay revived. Each one came back to life only briefly before slumping into a coma. The first survived eight hours before dying again. The second lasted five. For his third attempt in 1934, Cornish adjusted the formula, adding gum arabic to keep the heart from overworking itself back into failure. It was only with his fourth and fifth dogs, both named Lazarus, that the method properly held.
Lazarus IV, revived on 22 May 1934, survived but was left blind and unable to stand unaided. Within days it could crawl, bark and eat a substantial amount of food, though it never fully recovered. Lazarus V, revived the following year after being killed by an ether overdose, fared noticeably better, showing fewer impairments and recovering closer to normal function in a fraction of the time Lazarus IV had needed. Cornish took the improvement across his five attempts as evidence he was refining a genuine, repeatable method rather than getting lucky once.
Cornish Plays Himself in a Horror Film
The publicity from the Lazarus experiments reached well beyond the scientific press. Independent producer Eugene Frenke read about Cornish's work in a Time magazine article and pitched Universal Pictures on a film built around it. Cornish, who needed publicity to keep his research funded, agreed to take part. The resulting film, Life Returns, cast him as himself alongside professional actors including Onslow Stevens and Valerie Hobson, and its climactic scene, in which a dead dog is brought back to life on screen, wasn't a special effect. It was genuine footage lifted directly from Cornish's own May 1934 experiment.
Cornish was confident enough in the footage to put his name behind it directly. A card appearing in the film's credits, written by Cornish himself, stated plainly that everything shown was absolutely real and that the experiment had been recorded specifically to preserve a permanent scientific record. The film itself had a famously troubled release, delayed and re-edited for years, and became tangled in a lawsuit before finally reaching cinemas in 1938 under a different distributor entirely.
The publicity cut both ways. It made Cornish briefly famous, but it also displeased his university's officials, who wanted nothing to do with the attention a Hollywood horror picture was bringing to their institution, and it cemented an image of him as more showman than serious researcher, a reputation that would follow him for the rest of his career.
The Death Row Offer
Cornish stepped back from resuscitation work for a decade after the Lazarus dogs, but the idea never fully let go of him. In 1947 he resurfaced with a detailed plan to revive a freshly executed human prisoner. California at the time executed condemned inmates by lethal gas, and Cornish's proposal was built specifically around that method: as soon as physicians declared the body dead, he would strap it to the teeterboard, attach electrical heating pads to the limbs, and inject methylene blue into the veins to neutralise the poisonous fumes that had caused death. Pure oxygen would then be pumped into the lungs through a mask while the teeterboard rocked slowly to keep blood moving. Cornish said plainly that he believed the man would live.
Around this time, a San Quentin death-row inmate named Thomas McMonigle wrote to Cornish offering his own body for the experiment. McMonigle had been convicted of murdering Thora Chamberlain, a 14-year-old schoolgirl, and sentenced to death. His reasoning for volunteering was specific: if Cornish succeeded in reviving him, he believed America's double jeopardy protections would prevent the state from executing him a second time.
Cornish petitioned California for permission to carry out the experiment on McMonigle's body immediately after execution. The request was refused, and the reasoning was more specific than simple squeamishness. Because of the double jeopardy protections McMonigle himself was counting on, a successfully revived McMonigle would have had to walk free, with no legal mechanism left to punish a convicted child killer for his crime. State authorities weren't willing to risk that outcome to test an unproven medical technique, whatever the scientific interest. McMonigle was executed on 20 February 1948. No experiment followed.
What Was Left
Cornish's scientific reputation never really recovered from the human trial refusal. Funding dried up, and mainstream researchers increasingly treated his earlier work as a curiosity rather than serious science, the same skepticism that had followed him since the Life Returns publicity. By the late 1950s he had stepped away from resuscitation research entirely and reinvented himself, not as a scientist but as a small-time entrepreneur, marketing a product called Dr Cornish's Tooth Powder, formulated with vitamin D and fluoride.
There's a bleak irony buried in that final act. The powder's central selling point, that vitamin D helped prevent tooth decay, was a claim the American Dental Association had already explicitly rejected as scientifically unsupported back in 1945, years before Cornish started selling it. The man whose resuscitation work had been dismissed by the scientific mainstream spent his last working years peddling a product built on a health claim the dental establishment had dismissed in almost exactly the same way.
Robert Cornish died on 6 March 1963 in Alameda, California, at the age of 59. He never got the chance to find out whether a human being could have survived his teeterboard. Nobody has tried it since.
Frequently Asked Questions
How many dogs did Robert Cornish actually revive?
Across his 1934 trials he revived five dogs in total. The first three came back only briefly before slumping into comas and dying again within hours. The fourth and fifth, Lazarus IV and Lazarus V, were the ones that properly held, though both were left with lasting impairments.
Was Cornish considered a legitimate scientist at the time?
Opinion was divided even then. His early academic record was genuinely exceptional, but the resuscitation experiments and the Hollywood publicity around them led much of the scientific establishment to treat him as a showman rather than a serious researcher.
Did the death row inmate who volunteered actually get resuscitated?
No. California refused Cornish permission to attempt the experiment, and Thomas McMonigle was executed in 1948 with no resuscitation attempt made.
