[@thecatherd]

My parents were anti-vax when I was a toddler, so I didn't end up getting my MMR until I was 16 and "old enough" to make my own decision. Thankfully I managed to dodge the measles outbreaks when I was younger so I consider myself lucky to have not been affected before then. Getting the MMR was one of the first things I did when I gained legal autonomy.

[@luispadua8491]

Sceptagon Same here.

[@tigerlilly5579]

You were still benefitted by the vaccines, even though you didn't get them. When a large segment of a population gets vaccinated, it greatly reduces the chances of everyone getting the diseases, even those who aren't vaccinated. I grew up in the '50's and '60's and they didn't have the MMR vaccines or the chicken pox vaccine. Nearly every kid got those common "childhood diseases". Nearly all recovered fully. The vaccines we did have were for life-threatening diseases: smallpox, polio, diptheria, and whooping cough. They could be killers. - Joy F.

[@thecatherd]

tiger lilly I'm aware of this, we're incredibly lucky to be alive at a time when smallpox and whooping cough aren't much of a concern in the first world. I would still rather be vaccinated though.

[@tigerlilly5579]

Yes; you don't want to get those "childhood diseases" as an adult, especially the mumps, which can cause sterility if you get it as an adult male, and the chicken pox, which has been associated with shingles. I got my shingles vaccine, since I had chicken pox in childhood. - Joy F.

[@apostle333]

Chickenpox is often fatal for an adult. That's why you were likely brought to a "chicken pox party" as a child.

[@Phelixc]

I was expecting Ignaz Semmelweis when you said he finally got doctors to wash their hands... After all, Semmelweis had been nagging about this until his death and Lister kind of followed up on Semmelweis' theory (2 years after Semmelweis death).. I feel sorry for Semmelweis, he was not taken seriously during his lifetime, and died in an insane asylum before his procedures were accepted as good practice. So let us at least credit him posthumous for his pioneering work.

[@mschoplos]

Same! !! he's is after all the saviour of mothers :)

[@lorenyoung791]

Lister improved the lot of everyone who needed surgery. What with the medicalization of obstetrics, Semmelweis boosted the odds for . . . everyone who had a mother, as well as all their mothers.

[@beegood6700]

Thank you for correcting that info. So important to know!

[@EricPalmer_DaddyOh]

Was just reading about Semmelweis today. He should get more credit.

[@VicJang]

I just finished watching Vsauce2’s video about Dr. Semmelweis. He definitely deserves more praise. Lister built on top of Semmelweis work.

[@EyeLean5280]

My husband saved my life when insisted I go to the hospital when I thought I had a pulled abdominal muscle. Turned out to be my appendix and it was long overdue for rupturing. I had emergency surgery and survived. Thanks, honey!

[@karaa7595]

EyeLean5280 doctors are too eager to remove the appendix. they have recently discovered it is an essential organ to the proper functioning of the immune system. same with tonsils.

[@brianjack49]

Kara A i was going to die from constant sickness as a baby, it was all caused by my tonsils. Once i had gotten them removed i went 5 years without getting sick.

[@galaxymew5138]

It's mind blowing to think that doctors didn't even operate with clean clothes and equipment until late 19th century because they didn't know germs existed.

[@marlonmoncrieffe0728]

Tori Peacock Good luck!

[@NSRDevelopment]

Tori - I spent a good portion of my career as a professional virologist, university professor, and research scientist, and I can tell you there are many fascinating reasons to become a virologist. Way back when, and even still today, I considered viruses to be the last great frontier in medicine. The control of these entities has always been an exercise in strategy, since they are so integrally associated with the host cell. You can't just "shotgun" approach them with antibiotics as is done with several bacteria. Many years ago, I created and taught an elective course for senior medical students in Advanced Medical Virology that emphasized effective strategies, but that also sought to educate these young professionals on the history, social, and global political impact of viral infectious disease. I urge you to hold onto and follow that desire to become a virologist. As you learn about the great medical scientists of the past, realize you are the hope of our future! www.RogerKoment.com

[@MyMagicCookie6]

ok so they disinfect sewers back then but not their wounds, wtf history

[@romannasuti25]

MyMagicCookie6 it did kinda make sense, because to some the miasma theory of disease was still accepted. According to that model, diseases were more or less treated as poisonings, where some caustic chemicals could be used to remove "toxins" (actually microbes) from areas that would obviously be toxic. A wound wasn't considered abviously toxic, hence no sterilization until Semmelweiss and later Lister.

[@melTiceTiger]

(you will read this in Agent Smith's voice) --- IT'S THE SMELL

[@evilcam]

It is people like this that actually make me proud that I am a human. We still have lots of problems, but it is through people like these men who will find the solutions. You should do a follow up to this, with Norman Borlaug, Robert Koch, Paul Ehrlich, and probably a whole bunch of other people that deserve this sort of recognition.

[@LilliD3]

Ignaz Semmelweis, John Snow, Francesco Redi... All the scientists who inspired these scientists to make these discoveries but died without recognition.

Maybe he would be saving more lives with the measles vaccine if more people actually used it.

[@MurdoDW]

Oh well, as long as I'm vaccinated...😂

[@BlackHoleMan77]

+Stuart M actually the vaccine doesn't work 100% of the time. So the only way to be completely safe is to have everyone be vaccinated to protect those for whom the vaccine isn't effective/can't be vaccinated through herd immunity.

[@MurdoDW]

not true, herm immunity works on the pretence that those immunised are removed from the susceptible population to cause the rate of gain of infection in the population to be below 0, ie. the basic reproductive rate of the disease will be below 1.

[@A_Dopamine_Molecule]

How does a show as intelligent as SciShow have such a horrific comment section? I think looking through these gave me legit nausea.

[@DustinRodriguez1_0]

One of the things that has fascinated me since I was a child when finding out what people used to believe was why they believed the wrong thing, and why they resisted the truth when it was discovered. With spontaneous generation and germ theory, the biggest reason people refused to believe in microscopic organisms that could cause disease is because they believed that God created the world specifically for mankind. And in a world created specifically for mankind, it would not make sense for there to be organisms which man could not even see which could kill them. Lister's findings were fought against very vocally. Doctors, and people who supported doctors, found his ideas as tremendously insulting. The suggestion that doctors could be introducing infection to their patients while trying to heal them was seen as the most malicious smear on their character possible. When reading about Lister, it is usually explained (and I was surprised to not see it featured in this video) that he worked at a hospital in which many doctors would deliver babies immediately after performing autopsies, without washing their hands between tasks. Infant mortality in that hospital was astronomically high. Lister was seen as accusing the doctors of being babykillers. At the time, the public perception of doctors was seen as a crucial thing to preserve. Much of medical practice was as much superstition and guesswork as it was science, and doctors were seen as virtuous and doing their best to 'do no harm.' To face that people with the best intentions are actually causing tremendous damage and death is always difficult, especially for the people themselves. You see this a lot whenever parenting is discussed too. Parents are doing an important job, they have the best intentions, so no one, especially not most parents, is willing to consider that they might be doing far more harm than good.

[@johnnyonthespot4375]

[@meinbuch9458]

+Dustin Rodriguez Thank you for the enlightenment.

[@MsPeabody1231]

Dustin Rodriguez Good comment. Doctors are still viewed in that way today in many countries. However with the rise of the internet people with chronic illnesses are challenging doctors positions due to the fact they now can get easier access to scientific research papers and to other health care professionals around the world.

[@argella1300]

Virginia Apgar is a good one to include. She developed the APGAR score, basically a way of evaluating babies right after they're born to see if they're having any health issues (line trouble breathing, issues with circulation, body temperature, etc.)

[@prepperjonpnw6482]

argella1300 have you ever noticed only doctors babies get a perfect score? lol. When I worked in the medical field it was a common knowledge/joke. So one day a colleague and I pulled up on the computer all of the files for 5 of the hospitals that our company owned and guess what? Yep it was true lol

[@nins7457]

Fascinating video! Very thought provoking. Though I must add that Dr. Ignas Semmelweis truly deserves the first credit of who pioneered or coined the idea of hand washing. Even though no one believed his theory at the time the man still deserves some form of recognition. R.I.P: Semmelweis 💜

+SciShow -- Joseph Lister based his work on the groundbreaking work of Ignaz Semmelweis, who had long died at the time Lister published his proposals. from the english Wikipedia: "Semmelweis *proposed the practice of washing hands with chlorinated lime solutions in 1847* while working in Vienna General Hospital's First Obstetrical Clinic, where doctors' wards had three times the mortality of midwives' wards."

[@Choclocklate]

I totally agree, Semmelweis is just too often forget :/

This pisses me off they mention Lister but no mention at all of Semmelweis who basically gave up his life when he advanced the idea of hand washing. Lister influenced by Pastuer?

It should be noted Nicolas Appert perfected preserving food by canning years before Louis Pasteur.

I think as an addition to this list, Alan Turing should also be mentioned. He made the first 'Turing machine' which was the first basic computer. With the Turing machine he broke the enigma machine, the machine that the germans were using for al their communications. Historians have estimated that if Alan would not have cracked the enigma the war would continue for at least 2 years and he saved at least 14 million lives. But that estimation is only if Germany would not have won the war, because Germany was actually very close of winning. So therefor you might even say that Alan Turing saved countless of lives in Europe and also the way we think in Europe.

[@joyfrost7960]

How could you leave out Jonas Salk and Sabine? I was born in 1952 and polio was the killer and maimer of both children and adults. Polio was merciless and nobody knew how it spread. Parents were afraid to let their kids go out and play or go swimming in the summer because of it. My parents were highly educated and were not fearful of vaccines, thankfully, so I was among the earliest batch of kids who were vaccinated and finally protected from this horrible disease. Most kids lived through and made a full recovery from the "normal" childhood diseases of measels, German measels, mumps, and chicken pox as I did and every kid I knew did. All kids whose ancestors were of European and Mediterranean descent had some measure of restance to these diseases; not enough to prevent getting sick, but to prevent them from being serious or fatal. - JF

The U.S. President William McKinley is a good example of Lister's technique. When McKinley was shot, most American doctors were still doubtful of Lister's techniques, which meant their probing and prodding ended up introducing more infections into McKinley's wounds. He survived the gunshot, and probably would have survived the initial infection, but he eventually became septic and died. I read a book about it last year, "Destiny of the Republic" by Candice Millard - a very interesting read. Millard has a few narrative non-fiction books that are pretty well done. My favorite so far is "River of Doubt," about Teddy Roosevelt. One of my favorite books. =)

My ears perked up when I heard the name Merck. My husband's grandfather use to work for them by building computer programs that could break down all the chemical components in drugs (or something like that, my husband knows more about it than I do). The story goes that when Merck wanted to move their headquarters he refused to move, so they moved the company to his home town. I'm not sure exactly how true that is, but it's nice to imagine it is. He is now 94 years old living in the same house in Central New Jersey.

It's very nice to think that these people have saved so many lives and made our modern world so much safer. Thanks for informing us so we can raise our glasses every now and then to those great minds!

I saved my sister once! When her horse went down and landed on her leg when it was getting up it slipped, and before it fell again I quickly jumped off of my horse and ran and dragged her out if it had fallen on her the second time the angle and the were the horse fell it would have killed her. Thankfully she's was fine despite a bruised leg and a minor sprained neck. So that's the story of how I saved my sister from a falling horse

I really liked the point at the beginning about how science is collaborative and cooperative. There's a public perception that scientists, especially ones in history, are solo heroes, but that's not true! From lab assistants who wash dishes to the principal investigator of the lab, discoveries have many people to thank! :-)

surprise not to find Fleming the list

I was born a rhesus baby in 1943. I owe my life to Karl Landsteiner and Alexander Wiener who discovered the rhesus factor in blood in 1939. Fortunately I was sent to Birmingham children's hospital which managed to save my life. Regards from Redruth Arnold

[@attilarischt2851]

I personally would've also included Ignaz Semmelwis.

[@tiredteen8906]

Ive recently finished the book "the horror of early medicine" by mrs. Fitzharris, it is about Joseph Lister who basically made desinfecting bandages and Hygiene common in hospitals, he should be a saint he deserved way more fame!

An interesting case study I found was a friend of mine whose family was prone to autism. His parents decided to just delay his vaccinations for a few years. But one day, he caught a strain of the flu. It was to bad, just standard fly symptoms, but after that, he began to socially regress, and Autism manifested itself. That case has led me to wonder if a strong immune response, or even certain antibodies could be one of the triggers of autism

Chuck Norris and Hulk Hogan should have ran a science show together. I'd watch that.

[@gordonlawrence3537]

+Travor McDonald some of the scientists in WWII ended up UK Comandos or UK LDR or from the US perspective a few of them were Rangers specialists. One I read about had over 100 confirmed kills - one had over 30 knife kills alone. You just don't mess with people like that.

[@VincentZalzal]

Very good episode. This should become a new recurring theme : the history of great scientists that changed humanity!

[@jamiekerr5514]

I swear Semmelweis got doctors to wash there hands??

Not "glassgow", it's pronounced "Glazzgo"

[@hugoesson2803]

I'm genuinely surprised that Alexander Fleming wasn't on this list, considering he "invented" penicillin

[@BaroquerChick]

forever crying because Glasgow is pronounced with IPA z not s ;_;

[@chairmanmeaow6379]

+Missus Attila Who cares, scottish people pronounce everything backwards lol I live there and they say "Ken" instead of "know" and "wayne" instead of "kid".

[@chairmanmeaow6379]

***** I live just outside of glasgow but i'm not scottish myself so i've never noticed much difference between glaswegians and people from outskirts towns like kilmarnock, just me being ignorant i guess.

[@BaroquerChick]

Error 404: Hodor Not Found it's "wean". A contraction of scots "wee ane" which means "wee one". Just a people trying to cling to the last vestiges of their dialect. And *I* care. Obviously.

[@kittersmccat8847]

Error 404: Hodor Not Found as some one from Kilmarnock I can confirm your right

Spontaneous generation = If god can make human from dirt then god can make rat from garbage.

[@Soviet_Kitty]

So spontaneous generation doesn't exist?

[@DustinRodriguez1_0]

Yep. Plus, it wouldn't make sense if things humans can't see could be alive. God made the world for man. Only a malicious god would create a world that contained living things man could not see which could hurt or kill him, and god isn't malicious. That was the primary opposition to germ theory at the time, and it caused the deaths of untold numbers of people.

Oh, for fuck's sake, he didn't invent free electricity. He made a method of long distance magnetic power generation. The magnetic field would have to come from somewhere, and it wasn't efficient enough. Tesla wasn't a god.

The most important invention that probably has saved more lives in history is water purification by Robert Thom (1804) and the idea of water desinfection by John Snow (1854).

I think Fritz Haber is up there as well. Even though his discovery was the result of unideal pursuits, he has allowed for billions of people to be supported by agriculture that otherwise would not exist.

I feel like Ignaz Semmelweis got shafted here by your choice of Joseph Lister.

[@Leve2Games]

In other news about saving people: another settlement needs our help. I'll mark the location on your pip-boy.

[@RodeyMcG]

Whenever I see people mention Lister, I always feel sad for Ignaz Semmelwies; never gets a look-in. He tweaked the importance of Hand Hygiene a few decades before Lister, but nobody listened to him because a)he didn't link it to germ theory, and b)everyone hated him because he was a jerk. Still, he deserves the nod.
