10 Intriguing Facts About Joseph Lister

Surgical patients once routinely died from their operations, because physicians believed that bad air—not bacteria—was responsible for their post-operative infections. This changed in the 19th century with a British physician named Joseph Lister (1827-1912), who dedicated his life to learning what caused infections and how to prevent them.

Get to know the quiet, studious doctor who is often called “the father of modern surgery"—and who has both a mountain and a popular mouthwash brand named after him.

1. Joseph Lister's father helped usher in the modern microscope—and his son's future career.

As a child, Lister’s scientific curiosity was encouraged by his father, Joseph Jackson Lister, who was an English wine merchant and amateur scientist. The elder Lister's tinkering with early microscopes paved the way for today’s modern achromatic (non-color distorting) microscope—an accomplishment that would admit him to the Royal Society, the world’s oldest national scientific society.

In addition to dissecting small creatures, articulating their skeletons, and sketching the remains, the younger Lister—who knew from an early age that he wanted to be a surgeon—spent much of his childhood using his father's microscopes to examine specimens. He would rely on microscopes throughout his scientific career, using them to research the action of muscles in the skin and the eye, how blood coagulated, and how blood vessels reacted during an infection’s early stages.

2. Joseph Lister was English, but he spent most of his career in Scotland.

Lister was born in the village of Upton, in Essex, England, and studied at University College, London. After graduating and working as a house surgeon at University College Hospital—where he became a Fellow of the Royal College of Surgeons—the young doctor moved to Edinburgh, Scotland, to work as renowned surgeon James Syme's assistant at the Royal Infirmary [PDF].

The move was supposed to be temporary, but Lister ended up finding both professional and personal success in Scotland: He married Syme’s daughter, Agnes, and was eventually appointed Regius Professor of Surgery at the University of Glasgow.

3. Joseph Lister thought about becoming a priest instead of a doctor.

Like many young professionals, Lister sometimes had doubts about his career path. The physician received a devout Quaker upbringing, and at one point he considered becoming a priest instead of a surgeon. However, Lister’s father encouraged him to stay in medicine and serve God by helping the sick. Lister would ultimately leave the Quaker faith to marry Agnes Syme, who belonged to the Scottish Episcopal Church.

4. Joseph Lister struggled with depression.

While away at school, Lister came down with a mild case of smallpox. He recovered, but the health scare—along with the death of his older brother, who succumbed to a brain tumor—pushed him into a deep depression. The student left school in London and traveled around Britain and Europe for a year or so before returning to the university and pursuing his medical studies with renewed vigor.

5. Joseph Lister is the reason we sterilize wounds.

When Lister was a surgeon, bloodstained bed linens and lab coats weren’t washed, and surgical instruments were rarely cleaned. And even though Italian physician Fracastoro of Verona had theorized in 1546 that small germs could cause contagious diseases, nobody thought they had anything to do with wound infections. Instead, many surgeons believed that miasmas—or bad air—emanating from the wound itself were responsible.

Lister, however, trusted his own observations. As a young doctor-in-training, he noted that some wounds healed when they were cleaned and damaged tissue was removed. However, the problem of infection continued to plague Lister through his career until he encountered the work of French scientist Louis Pasteur, who discovered that microbes could cause infection.

Intrigued, Lister began using a formula of diluted carbolic acid—a coal-tar derivative used to kill parasites found in sewage—to sterilize medical instruments and wash his hands. He also applied this mixture to bandages, and sprayed carbolic acid in operating rooms where surgeries resulted in high mortality. He reported the results at a meeting of the British Medical Association in 1867: "my wards […] have completely changed their character, so that during the last nine months not a single instance of [blood poisoning], hospital gangrene, or erysipelas has occurred in them.”

While some physicians balked at his techniques, claiming they wasted time and money, Lister’s approach caught on. Soon, physicians in Germany, the U.S., France, and Britain were following his lead. As for Pasteur and Lister, the two scientists corresponded, and would finally meet in person for the first time in 1878. And at Pasteur's 70th birthday celebration in 1892, Lister gave a praise-filled speech about the life-saving benefits of Pasteur's research.

6. He was kind to patients.

Lister referred to some patients as "this poor man" or "this good woman" (he refused to call them "cases"), and he always tried to keep them calm and comfortable pre-and post-operation. Once, the surgeon even sewed a doll's missing leg back into place for a young charge.

7. He treated Queen Victoria ...

Lister's most famous patient was Queen Victoria: In 1871, the surgeon was called to the monarch's estate in the Scottish Highlands after the queen sprouted an orange-sized abscess in her armpit. Armed with carbolic acid, Lister lanced the mass, drained its pus, and dressed and treated the wound to prevent infection—but at one point, he accidentally sprayed his disinfectant in the displeased queen's face.

Lister would later joke to his medical students, "Gentlemen, I am the only man who has ever stuck a knife into the queen!"

8. ... who later made him a baron.

As Lister's fame grew, Queen Victoria made him a baronet in 1883. Later, she elevated the physician to baron status. Lister would remain beloved among members of the royal family, including Edward VII, who was diagnosed with appendicitis two days before his royal coronation in 1902. His doctors consulted Lister before performing a successful surgery, and the king made sure to thank him once he was crowned. "I know that if it had not been for you and your work, I wouldn’t be sitting here today," the monarch told Lister.

9. Listerine mouthwash is—surprise!—named after Joseph Lister.

Even if you didn’t learn about Lister in science class, you’ve probably used his namesake formula: Listerine. The popular mouthwash brand—which is promoted with the slogan "Kills germs that cause bad breath"—was originally invented in 1879 by American physician Joseph Lawrence. Lawrence had created the green liquid as an alcohol-based surgical antiseptic, and he fittingly named the product after his pioneering predecessor. However, Listerine would ultimately be marketed for oral hygiene purposes, after first being peddled as a cigarette additive, a cure for the common cold, a dandruff treatment, and more.

10. Lister also has a mountain named after him.

Lister has public monuments and hospitals dedicated to him around the world, but if you travel to Antarctica, you may also encounter a massive mountain named in his honor: At around 13,200 feet, Mount Lister is the highest point in the Royal Society Range, a mountain range in Victoria Land, Antarctica, that was first explored by the British during the Discovery Expedition from 1901 to 1904. This expedition was organized by the Royal Society and the Royal Geographical Society—and since Lister was the Royal Society’s president from 1895 to 1900, the range’s most majestic peak was named after him.

More Than 350 Franklin Expedition Artifacts Retrieved from Shipwreck of HMS Erebus

From a shallow Arctic gulf, a treasure trove of objects from the HMS Erebus shipwreck has been brought to the surface for the first time in more than 170 years. The items could offer new clues about the doomed Franklin expedition, which left England in 1845 to search for the Northwest Passage. All 129 people perished from still-uncertain causes—a mystery that was fictionalized in the AMC series The Terror in 2018.

Marc-André Bernier, head of underwater archaeology at Parks Canada, said in a teleconference from Ottawa that this year’s research season was the most successful since the discovery of the HMS Erebus shipwreck in 2014. Parks Canada divers and Inuit located the HMS Terror, the second ship of the Franklin expedition, in 2016.

From mid-August to mid-September, 2019, the Parks Canada and Inuit research team began systematically excavating the large and complex shipwreck. “We focused on areas that had not been disturbed since the ship had sunk,” Bernier said. “Right now, our focus is the cabins of the officers, and we’re working our way toward the higher officers. That’s where we think we have a better chance of finding more clues to what happened to the expedition, which is one of the major objectives.”

Over a total of 93 dives this year, archaeologists concentrated on three crew members’ cabins on the port side amidships: one belonging to the third lieutenant, one for the steward, and one likely for the ice master. In drawers underneath the third lieutenant’s bed, they discovered a tin box with a pair of the officer’s epaulets in “pristine condition,” Bernier said. They may have belonged to James Walter Fairholme, one of the three lieutenants on the Erebus.

In the steward’s pantry, where items used to serve the captain were stored, divers carefully brushed away sediment to reveal dozens of plates, bowls, dish warmers, strainers, and more— about 50 serving pieces total. Bernier said some of the most exciting finds were personal objects that could be linked to individuals, such as a lead stamp with the inscription “Ed. Hoar,” for Edmund Hoar, the 23-year-old captain’s steward. They also found a piece of red sealing wax with a fingerprint of its last user.

Other intriguing items brought to the surface include a glass decanter, found in the officers’ mess area on the lower deck, which may have held brandy or port; a high-quality hairbrush with a few human hairs still in the bristles; and a cedar-wood pencil case. All of the artifacts are jointly owned by the Government of Canada and Inuit.

The extensive recovery was made possible by a new research barge, which was moored over the shipwreck and provided hyperbaric chambers and hot-water suits. While wearing the suits, divers were able to stay in the frigid waters for about 90 minutes at a time; they spent over 100 hours examining the wreck this year.

The HMS Erebus’s size and excellent state of preservation mean there’s much more to discover, Bernier said. The Erebus is 108 feet long, and though the upper deck has collapsed, there are 20 cabins on the main deck. They’ve examined only three so far. “There are tens of thousands of artifacts still there,” Bernier tells Mental Floss. “We’re going to be very focused and save what needs to be saved, and go to places [in the wreck] where there are good chances of finding the most information that is valuable for the site.”

As with the findings from previous research seasons, many questions about the shocking demise of the Franklin expedition remain unanswered. How and when did the HMS Erebus sink after both ships were abandoned in spring 1848, having been trapped in ice since September 1846? Which officers and crew were among the 24 men who had died by that time, and why so many?

Bernier tells Mental Floss there’s even a new mystery to solve. Near Edmund Hoar’s items, divers found another artifact that also bore the name of a crew member—mate Frederick Hornby. “Originally, when the ships set sail, he was not on Erebus, he was on Terror,” Bernier says. “So this object jumped ship at one point. How did that happen? Was Hornby transferred to Erebus; did they abandon one ship and put everybody on the other one? Was it something somebody recovered after he died? Was it given to somebody? With one object, we can start to see [new] questions. Hopefully, by piecing all of this together, we can actually start pushing the narrative of the story in some interesting direction.”

The Reason Our Teeth Are So Sensitive to Pain

On a good day, your teeth can chew through tough steak and split hard candy into pieces without you feeling a thing. But sometimes, something as simple as slurping a frosty milkshake can send a shock through your tooth that feels even more painful than stubbing your toe.

According to Live Science, that sensitivity is a defense mechanism we’ve developed to protect damaged teeth from further injury.

“If you eat something too hot or chew something too cold, or if the tooth is worn down enough where the underlying tissue underneath is exposed, all of those things cause pain,” Julius Manz, American Dental Association spokesperson and director of the San Juan College dental hygiene program, told Live Science. “And then the pain causes the person not to use that tooth to try to protect it a little bit more.”

Teeth are made of three layers: enamel on the outside, pulp on the inside, and dentin between the two. Pulp, which contains blood vessels and nerves, is the layer that actually feels pain—but that doesn’t mean the other two layers aren’t involved. When your enamel (which isn’t alive and can’t feel anything at all) is worn down, it exposes the dentin, a tissue that will then allow especially hot or cold substances to stimulate the nerves in the pulp. Pulp can’t sense temperature, so it interprets just about every stimulus as pain.

If you do have a toothache, however, pulp might not be the (only) culprit. The periodontal ligament, which connects teeth to the jawbone, can also feel pain. As Manz explains, that sore feeling people sometimes get because of an orthodontic treatment like braces is usually coming from the periodontal ligament rather than the pulp.

To help you avoid tooth pain in the first place, here are seven tips for healthier teeth.
