Disappearing Spoon: The Murderous Origins of the American Medical Association
In this episode of The Disappearing Spoon, Sam Kean talks about the strange origin story of the American Medical Association. The creation of this powerful medical society can be traced back to a duel between two doctors at Transylvania University in Kentucky.

The Big ‘What If’ of Cancer
In this episode of The Disappearing Spoon, Sam Kean talks about Hermann Muller, a geneticist who in the 1920s discovered that radiation causes genetic mutations. This discovery happened around the same time that other geneticists were starting to link cancer with genetic mutations. Had both of these parties communicated they would have gotten a 50-year head start in cancer research. So why didn't scientists make this realization sooner? It turns out that Muller was a real jerk.

Disappearing Spoon: The Harvard Medical School Janitor Who Solved a Murder
On this episode of The Disappearing Spoon, Sam Kean talks about a murder mystery that rocked Boston in 1849. Harvard University alum and physician George Parkman had gone missing. The last place he was seen alive was at the Harvard medical building, which had plenty of bodies, but police couldn't find Parkman’s there. That is until a janitor intervened and implicated a medical school professor. The ensuing murder trial was a media circus equivalent to the O. J. Simpson trial. And just like that trial, it also familiarized the layperson with forensic and anatomical sciences.

Disappearing Spoon: Burn After Watching
In this episode of The Disappearing Spoon, Sam Kean breaks down the history of nitrocellulose. This thick, transparent liquid was the world’s first plastic and could be shaped into anything, including billiard balls and photography film. With nitrocellulose film, you could run reels of pictures together quickly, which gave birth to the first movies. The only fatal flaw with this plastic is that it’s also extremely combustible—so much so that it can burn underwater once it gets going. This led to notable tragedies in movie theaters, as well as in hospitals that used nitrocellulose X-rays such as the Cleveland Clinic Hospital, where 122 people died in a fire in 1929.

History’s First Car Crash Victim
In this episode of The Disappearing Spoon, Sam Kean talks about Mary Ward, a budding naturalist and astronomer from Ireland. She spent a lot of time observing plants and animals through a microscope and published a book of detailed sketches that dazzled readers and colleagues in the 1800s. However, her career was cut short by a strange curiosity of that time period: the automobile. They weren’t the same cars that are around today, but her death was the first car death recorded in history, and it foreshadowed the carnage the automobile continues to leave behind.

Real Life Zombies
In this episode of The Disappearing Spoon, Sam Kean talks about memory fugues, a psychological disorder that wipes out biographical information from people’s brains. It is estimated that roughly 1 in 100,000 people seeking help for mental disorders have them. This disorder happens worldwide and it usually afflicts people in their 20s. Scientists have only recently started to piece together what is going on in the brains of those impaired by it.

How Climate Change Will Remake the Human Body
On this episode of The Disappearing Spoon, Sam Kean delves deep into the science behind the evolution of animal and human bodies. Like animals, human bodies have also evolved to adhere to the demands of ever-changing climates. This raises a question: how will human bodies respond to climate change?

The ‘Mary Poppins’ Cancer
In this episode of Disappearing Spoon, Sam Kean discusses the horrors of a particular genetic disease that was, literally, sweeping through London in the 1700s. In 1666, the Great Fire of London consumed about 13,000 homes and caused the modern equivalent about $1.3 billion in damage. After the Great Fire, London officials made chimneys mandatory in all homes and buildings. All these new chimneys meant there was a big demand for sweepers. Who did they employ to clean these narrow, soot-filled chimneys you ask? Very young boys.

Disappearing Spoon: Kangaroo (and Pig and Monkey and Dog and Donkey) Courts
Animal trials have always been part of society, but we are not talking about the ones with lab mice. In medieval times dozens of animals were tried in human courts for committing human crimes. It sounds silly, but the practice raises an uncomfortable question that we are still grappling with today: if we hold animals accountable in court, doesn’t that mean that they deserve some sort of legal protection? We kill them for food and skin them for leather after all. What about medical and product trials that sacrifice thousands of animals despite the fact that they have had diminishing returns throughout the years?

Murder, Fraud, Sabotage, Piracy, and Other Dastardly Deeds Perpetrated in the Name of Science
The Disappearing Spoon, a podcast collaboration between the Science History Institute and New York Times best-selling author Sam Kean, returns for its second season on October 5, 2021. To celebrate, our producer, Rigoberto Hernandez, sat down with Kean to talk about his new book The Icepick Surgeon: Murder, Fraud, Sabotage Piracy, and Other Dastardly Deeds Perpetrated in the Name of Science. This interview is a great companion piece for The Disappearing Spoon series since some of the stories in the book relate directly to some of the stories in the upcoming season. In this interview Kean talks about some of the case studies in his book, including how Thomas Edison shifted his ethics on the death penalty because of a grudge, how a part-time chemist from Philadelphia became an unlikely spy, and how an American doctor purposefully infected people in Guatemala with venereal diseases—all in the name of science.
