    When I think about Heddy LaMar, my brain switches to Blazing Saddles, but I digress… I won't have a go at you, Simon. A preamble before the video. THAT cracked me up! Awesome video and I am reminded how much events are shaped by the actions or inactions of others; thus, creating history. Please find ten more. LOL

    Oh dear Simon…MMR is the measles, mumps, and rubella…the meningitis vaccine is completely separate…

    Intentionally or not, Andrew Wakefield is largely responsible for the resurgence of preventable diseases and for totally unnecessary suffering and death. He is a prime example of how the publication a seemingly intelligent paper in a respected publication can have disastrous results.

    Actually, Germany wanted to exile the Jews to the Middle East, but the Muslims weren't having it.

    I guess there are a lot of us around today that may not have been, if not for the vaccines talked about here and the other medical breakthroughs.  Be fore we got the polio vaccines, we had two kids in my school come down with polio.  I have served in areas where certain diseases could be found, if not for the required vaccines, there would be many of us who would have been sick.  I came down with typhoid, if not for the vaccines that I had already taken, the course of the disease would have been much worse, at least my body was able to fight off the disease a lot better.  Just do not understand why so many people today are afraid the have their children vaccinated the child hood diseases.  Just do not understand that mind set.

    #10 The idiotic young man who happened to be Jewish and give the Nazis an excuse. Never knew his name now I feel sorry for him if he did survive the war he survive knowing that he was the cause of millions of dead. But the truth of the matter is they would have scapegoated someone else if it hadn't been him.

    I was told many years ago that the number 10 entry about Herschel Grynszpan was the inspiration for Queen's Bohemian Rhapsody, if you listen to the song keeping the story in mind it sort of makes sense.

    Poor Percy Julian that's part of why black people are struggling today they put barriers in front of them and didn't allow Black people to compete educationally…White people have had a head start and we still catching up

    Kristallnacht translates to “crystal night,” as all know because of the broken glass littering the streets. It’s only the “night of broken glass” to English speakers because calling it the “Crystal Night” sounds too pretty for western brains to conceive of when it comes to such a horrid occasion.

    Why don't black people in America talk abut Percy Julian instead wasting time on Kanye West and his stupid rants?! That is real black empowerment. He didn't waste time looking for white people to blame. He made something great of himself and actually benefited the world.

    Wakefield has been struck off in the UK for several reasons. Firstly he eventually admitted faking the data. Secondly he was being sponsored by a group of American law firms representing Anti-vaxers who were trying to pin Autism and Asperger's on the MMR jab (and he never declared this conflict of interest until prosecuted).

    yep the damage has been done loads of people now wont vaccinate their kids and babies incause they get autism and relay on 'natural' remedies or that any illnesses they get will just go away or antibiotics. But did they know that some of the smartest people out there have asbergers which a mild version of autism. And also I would have been dead today if I didn't get vaccinations as I had a dodgy kidney when I was born.

    Hi, I am one of those that says something about pronunciation. Truly, the only time I complain about creators pronunciations, it when it is a city or Towns name. because I want to know where they are talking about. sometimes it is so bad, that you as a listener are left scratching their heads, thinking WTF is that. And the speaker was talking about the listeners' hometown. I try to be nice & a little funny about it not rude or condescending or petty or like a twatwaffle. But for the most part, Simon your pronunciation is spot on… might I add, hopefully not without sounding cringy, or pervy, a very attractive voice & cadence. As a daily listener, I quite enjoy & find the information very interesting, well researched, presented with humor….. Thank you.

    Some of these people changed the world for the better, and some for the worse. I'm not sure that Flexner's changes were all for the better. Improving medical schools was one thing, but more restrictions on medical schools and doctors meant fewer doctors and higher pay for doctors, so medical care became more expensive and less accessible.

    This video almost makes me sad 😢 There's some great minds being overlooked as we progress through time so quickly. Ironic that in the Technology Age, we have access to all information and still know so little.

    I'm not sure Apple was much into C prior to the move to the BSD-derived OS X – classic MacOS was Pascal-centric, no?

    I knew about Hedy Lamarr already…it's sad that such a brilliant woman became famous for her looks and sex appeal rather than her intelligence. On the other hand, "Dr" Wakefield should have his balls cut off and rammed down his throat, because (speaking as a person at the high-functioning end of the Autism spectrum) I think Jenny McCarthy and her cohorts are as bad as the fracking Nazis, because not only do they insist on promoting a theory that has been debunked by legitimate medicine, the "treatments" they claim will "cure" or "manage" Autism are basically torture, starvation, and sexual abuse. If it were legal to do so, they should all be sterilized and have their children taken from them!

    This is the third time Simon's been all like "The pronunciations are hard, I'm trying." You can't let the comments section push you around, Simon. If Teen Titans Go, an objectively bad show and thing, can look at their comments and laugh them off, surely you don't have to feel self conscious about words that are hard to pronounce, right?
