6 great inventions from the Civil War

The massive number of casualties and injuries created during these battles necessitated some quick, creative ideas... some of which we still have today.

  • The war resulted in more than 600,000 deaths.
  • About 500,000 were wounded.
  • The war created a massive need for inventions of various kinds and led to rapid advancement in medicine

There were several things newly invented during the Civil War that became keys to saving lives, as well as taking them. The Gatling Gun and repeating rifles, both invented just before or during the war, became quite effective at slaughter, as well as producing wounded men in unprecedented numbers.

Because such a devastating and massive war usually generates rapid advancement along medical fronts, inventions and new discoveries came fast and furious during those four years.

1. Rapid amputations

There was a reason amputations were streamlined during the war — and it was not because the surgeons and other medical staff were not capable. In 1840, a new kind of bullet was invented; the Minié Ball, named for its inventor.

This was 0.58 caliber — slightly smaller than the end of an adult human thumb. Due to their usage in rifled barrels, this bullet dramatically increased the accuracy of weapons of the time, as well as their damage. Rapid amputations were "invented" and practiced during the Civil War partly because of the sheer number of casualties and the need for the injured to be quickly stabilized. But the primary reason was because that very same Minié Ball caused such fragmentation and shattering of bone, ligaments, muscle, and flesh, that if amputation were not performed, then complications such as gangrene and infection — followed by death — were certain.

The solution? Cut the limb off well above the damaged area.

2. Anesthesia inhaler

With that many surgeries going on at once, pretty much constantly during most battles, there had to be a way to mercifully knock these people out while their limbs were amputated. Chloroform and ether were invented just 15 years before the war began, and they had not been deployed for use on battlefields involving mass casualties yet.

When available, chloroform was the go-to on Civil War battlefields, because ether was extremely flammable. It was usually applied via cotton balls, handkerchief, etc. This, however, wasted much of the precious drug.

The invention that saved a lot of soldiers from excruciating pain (something on the order of 95 percent of those who endured surgery for such wounds) was the anesthesia inhaler, invented just before the war and deployed as the field hospitals began to have an extreme need. These enabled medical staff to rapidly give chloroform to multiple soldiers with as little waste as possible. And, still to this day, a modern variant of that invention is used (with newer, superior intoxicants) before and during surgeries.

3. The ambulance-to-emergency-room system

One of the early high-casualty battles of the Civil War was the First Battle of Bull Run (or Manassas, as it's known to Southerners), which began on July 21, 1861. The soldiers who ended up being hurled into the fight had no idea what to expect; many of the Union forces were 90-day volunteers that President Abraham Lincoln had sought after Fort Sumter fell to Confederates. There were many gatherings of people watching the fight; expecting nothing as severe as what was to come, some bystanders — including a few dozen senators, and enterprising people selling pies and other food — setup picnic blankets and watched. But when the horror unfolded, many of them got in their carriages and headed back from whence they came.

Fleeing with those non-soldiers, however, were most of the private ambulances hired to help out; they'd never seen such carnage, and this experience terrified them, causing them to flee just as they were needed.

A few days later, when the full extent of the back-and-forth was over, there were 3,000 casualties on the Union side and about half of that on the Confederate side. Many lay dying for hours on the fields, since the concept of quickly ferrying the wounded to field hospitals was not yet invented — and all of the private ambulances hired had skedaddled.

The Medical Director of the Army of the Potomac, Jonathan Letterman, got to work immediately after Bull Run, and devised an ingenious "ambulance-to-E.R." system involving the use of existing soldiers and medical staff that is still basically in use today. By the time of the Battle of Antietam in September, it was fully deployed, with 50 ambulances containing a driver and two stretcher-bearers each, to quickly get the injured to field hospitals.

4. Plastic surgery

Before the U. S. Civil War, reconstructive plastic surgery, especially of the face, didn't really exist — it had been theorized in the medical journal known as The Lancet in 1837, and before that, facial reconstruction was limited to taking skin flaps and bone from other parts of the body to form facial features. But with over 10,000 cases of gunshot and cannon shrapnel wounds to the faces of various soldiers during the war, the need for something to at least partially reconstruct facial features was pretty dire. That put it high on the priority list.

Of course, with it being more or less experimental in nature and very much in need of research and testing, it couldn't be deployed for very many of those 10,000; indeed, it was successfully performed on only about 30 former soldiers or officers.

5. Embalming

The act of "arterial" embalming the dead — replacing their blood with chemicals to preserve the body long enough to get through services and burial — had been invented in France about 25 years before the Civil War.

But it took until the end of the war for it to really catch on in the United States; the casualties from the war itself were partly why. Up until that time, a family member dying usually meant the body would not be preserved, but would rather decompose within a few days or a week. This meant funeral services happened quickly, by necessity. And even then, the body was frequently surrounded in candles and other masking scents.

Most of the over 600,000 soldiers who died during the entire war were either put into mass graves or left where they lay in the fields and trenches. Only those with wealthy families had their bodies retrieved for services back home — and even then, all of those arrangements had to be made quickly, or the bodies would be too decomposed for even recognition. The science of embalming was still relatively new, so various experiments in the practice were conducted on deceased soldiers; indeed, 40,000 of the 600,000 dead were embalmed during the entire 4-year period. It was "catching on."

Fast forward to the end of the war, when Abraham Lincoln was assassinated. His body was quickly embalmed, and then placed on a funeral train that worked its way across the country to Illinois.

Even then, the new process wasn't effective enough to keep the body preserved for the entire two-week trip. While people near the early train stops marveled that his appearance was so life-like — they even tried to reach out and touch him — near the end of the funeral train stops, Lincoln's face appeared hollow and gaunt. It was time for him to be lowered into the family burial plot.

Still, the experience of seeing and hearing about Lincoln's funeral train's visit to 180 cities made the concept of embalming the dead a permanent part of U.S. culture.

6. Hinged prosthetic limbs

Because amputations of the leg were considered worse than those of the arm due to the social impact as well as the ability to work on the farm and in factories, the lack of a prosthesis for either leg was becoming a big problem for soldiers returning home missing a lower limb.

One Confederate Virginia soldier, James Edward Hanger, was wounded early in the war, during the Battle of Philippi. When he returned home, his leg amputated just below the left hip, he disappeared into isolation — his family assuming he was depressed and didn't want anyone to see him in the state he was in. This was true, however, Hanger approached that isolation from a creative and nuanced angle: His missing leg was a problem to solve.

I cannot look back upon those days in the hospital without a shudder. No one can know what such a loss means unless he has suffered a similar catastrophe. In the twinkling of an eye, life's fondest hopes seemed dead. I was the prey of despair. What could the world hold for a maimed, crippled man!

Up until that time, leg replacements were simple devices, usually "peg" legs, stiff and definitely not something that would enable someone to have a gait that was at all normal.

He created not just the first jointed leg prosthetic out of barrel staves, rubber, joints, nails, and hinges, but a revolution in an industry that was about to explode. The "Hanger Limb" went from being a creation out of necessity to an industry that won a state grant to mass produce them in Virginia, and then after the war, a U. S. patent, and factories were setup in major cities across the world, making the limbs commonplace and effective for amputees of the Civil War as well as all other wars since.

Indeed, today Hanger, Inc. remains the largest maker of prosthetics in the world.

An organism found in dirt may lead to an anxiety vaccine, say scientists

Can dirt help us fight off stress? Groundbreaking new research shows how.

University of Colorado Boulder
Surprising Science
  • New research identifies a bacterium that helps block anxiety.
  • Scientists say this can lead to drugs for first responders and soldiers, preventing PTSD and other mental issues.
  • The finding builds on the hygiene hypothesis, first proposed in 1989.

Are modern societies trying too hard to be clean, at the detriment to public health? Scientists discovered that a microorganism living in dirt can actually be good for us, potentially helping the body to fight off stress. Harnessing its powers can lead to a "stress vaccine".

Researchers at the University of Colorado Boulder found that the fatty 10(Z)-hexadecenoic acid from the soil-residing bacterium Mycobacterium vaccae aids immune cells in blocking pathways that increase inflammation and the ability to combat stress.

The study's senior author and Integrative Physiology Professor Christopher Lowry described this fat as "one of the main ingredients" in the "special sauce" that causes the beneficial effects of the bacterium.

The finding goes hand in hand with the "hygiene hypothesis," initially proposed in 1989 by the British scientist David Strachan. He maintained that our generally sterile modern world prevents children from being exposed to certain microorganisms, resulting in compromised immune systems and greater incidences of asthma and allergies.

Contemporary research fine-tuned the hypothesis, finding that not interacting with so-called "old friends" or helpful microbes in the soil and the environment, rather than the ones that cause illnesses, is what's detrimental. In particular, our mental health could be at stake.

"The idea is that as humans have moved away from farms and an agricultural or hunter-gatherer existence into cities, we have lost contact with organisms that served to regulate our immune system and suppress inappropriate inflammation," explained Lowry. "That has put us at higher risk for inflammatory disease and stress-related psychiatric disorders."

This is not the first study on the subject from Lowry, who published previous work showing the connection between being exposed to healthy bacteria and mental health. He found that being raised with animals and dust in a rural environment helps children develop more stress-proof immune systems. Such kids were also likely to be less at risk for mental illnesses than people living in the city without pets.

Lowry's other work also pointed out that the soil-based bacterium Mycobacterium vaccae acts like an antidepressant when injected into rodents. It alters their behavior and has lasting anti-inflammatory effects on the brain, according to the press release from the University of Colorado Boulder. Prolonged inflammation can lead to such stress-related disorders as PTSD.

The new study from Lowry and his team identified why that worked by pinpointing the specific fatty acid responsible. They showed that when the 10(Z)-hexadecenoic acid gets into cells, it works like a lock, attaching itself to the peroxisome proliferator-activated receptor (PPAR). This allows it to block a number of key pathways responsible for inflammation. Pre-treating the cells with the acid (or lipid) made them withstand inflammation better.

Lowry thinks this understanding can lead to creating a "stress vaccine" that can be given to people in high-stress jobs, like first responders or soldiers. The vaccine can prevent the psychological effects of stress.

What's more, this friendly bacterium is not the only potentially helpful organism we can find in soil.

"This is just one strain of one species of one type of bacterium that is found in the soil but there are millions of other strains in soils," said Lowry. "We are just beginning to see the tip of the iceberg in terms of identifying the mechanisms through which they have evolved to keep us healthy. It should inspire awe in all of us."
