The Origin of Weird: Thalidomide Babies

A tiny pill promised calm nights and easier mornings, then left a generation of families asking how a “safe” sedative could cause so much harm. We unravel the thalidomide story from its meteoric rise as a gentle sleep aid to the global wave of birth defects that followed, tracing how a single oversight in early pregnancy testing reshaped medicine, regulation, and public trust.

We walk through the crucial developmental window—roughly weeks three to eight after conception—when limbs, ears, and organs form, and explain how thalidomide’s interference with embryonic blood vessel growth led to phocomelia and other severe defects. You’ll hear how two physicians, Widukind Lenz in Germany and William McBride in Australia, independently connected the dots, and why the pattern they saw forced governments to pull a best-selling drug from shelves worldwide. We also spotlight Frances Oldham Kelsey at the FDA, whose insistence on stronger data kept thalidomide from broad U.S. approval and likely spared thousands of families.

The conversation doesn’t stop at crisis. We examine the regulatory revolution that followed: stringent proof of safety and efficacy, phased clinical trials, and rigorous reproductive risk evaluation. We also explore the drug’s surprising second act—its tightly controlled use for complications of leprosy and multiple myeloma—and what that says about the thin line between harm and healing in pharmacology. Most importantly, we center survivors who adapted with courage and helped drive disability rights and drug-safety reform.

If you care about medical history, bioethics, FDA oversight, and how evidence builds (or breaks) trust, this story matters. Subscribe, share with a friend who loves health and history, and leave a review to tell us what part of the thalidomide saga surprised you most.

Oh hey there.

SPEAKER_01 0:17

Oh hey there.

SPEAKER_00 0:20

I am Fred. I am Kate. This is This is take two. We had cat incidences. Too many of them to they they sneak in and then they attack the cords and no, Oliver attacks the cords. Oliver attacks the cords. Anyway, so this is take two. Um we're starting over. How are you? History of Buffoons. Okay. Yes. This is um the origin of Weird History Foons, and today we're going to talk about phthalidomide babies.

SPEAKER_01 0:55

Yes, I am well. How are you? This is so. Do you ever like drive by a car crash and just like you know, people are gawking, like, oh, what happened?

SPEAKER_00 1:07

Oh, for sure. Rubbernecking.

SPEAKER_01 1:09

Yeah. Yeah. Um, that's what people would be doing if they watched this right now. Look at that car crash. Thalodomide.

SPEAKER_00 1:20

Thalodomide babies. So in the late 1950s, doctors and pharmacists across Europe began recommending what seemed like a miracle drug.

SPEAKER_01 1:30

Which is never it's never a miracle. No, because with all the miracle drugs we've had in over time, and it's funny because it seems like a lot of them came from prior times to us, and it's like, eh, did you really know?

SPEAKER_00 1:46

Yeah. Okay. So it came in small tablets, easy to swallow, and it promised a really good night's sleep.

SPEAKER_01 1:54

Did they also come in chewable form?

SPEAKER_00 1:56

Not at the time.

SPEAKER_01 1:57

Did they put did they put so they did later?

SPEAKER_00 2:00

We don't know. Okay.

SPEAKER_01 2:01

Maybe perhaps put it in the Flintstones vitamins.

SPEAKER_00 2:04

Did you grow up on those? I did. I totally did, too.

SPEAKER_01 2:07

Yeah, I think most of our generation did, to be honest.

SPEAKER_00 2:10

It was just candy, basically.

SPEAKER_01 2:12

100%.

SPEAKER_00 2:13

So the medication was called thalodomide, and it was marketed as a gentle sedative. Okay. It was easy. Nope. It was impossible to overdose on.

SPEAKER_01 2:25

Which again, the human race finds a way.

SPEAKER_00 2:28

And um, unlike other sleeping pills of that era, it had no serious side effects.

SPEAKER_01 2:35

That they knew of.

SPEAKER_00 2:36

And so for people struggling with insomnia, anxiety, morning sickness, even during pregnancy, it was a blessing. So pregnant women were encouraged to take this. Doctors believe that it helped nausea during um early pregnancy.

SPEAKER_01 2:51

Is it nausea or nausea?

SPEAKER_00 2:54

For tomato tomato.

SPEAKER_01 2:56

Is that I think so. Okay. I always was curious because I think I say nause nausea.

SPEAKER_00 3:00

Yeah. I think it's tomato tomato. Okay, gotcha. Um, so pharmacists sold it um confidently in several countries. It didn't require a prescription. Um, the drug was so widely trusted that some advertisements suggested that it was safe enough for both mother and unborn child.

SPEAKER_01 3:17

Oh boy.

SPEAKER_00 3:18

And for a while, nothing was wrong.

Marketed As Safe For Pregnancy

SPEAKER_01 3:21

Until those mothers, let me guess, started having babies. Hence the thal thalodamide. Am I saying it right?

SPEAKER_00 3:31

Sure.

SPEAKER_01 3:31

Sure.

SPEAKER_00 3:32

I mean, who knows if I'm saying it right. So touche. Um, around 1959 and 1960, something strange became h began happening in the maternity ward in Europe.

SPEAKER_01 3:46

Yeah.

SPEAKER_00 3:47

Doctors started noticing babies were born with severe and unusual deformities.

SPEAKER_01 3:54

Okay, let's get a rundown here. What are they?

SPEAKER_00 3:57

Some infants were born without arms.

SPEAKER_01 4:00

Like, so it was just straight, not not even a nub, just straight, no arms. I mean, I haven't looked at pictures. And I don't think I want to. Yeah. Because that sounds fucking horrible. Yeah. Oh, yeah.

SPEAKER_00 4:12

Others had legs that were extremely shortened. Um, in certain areas, this is wild, hands seemed to grow directly from the shoulders or feet from the hips.

SPEAKER_01 4:27

That so, like kind of like when I think of the feet like that, I think of E.T.

SPEAKER_00 4:33

Yeah. Right?

SPEAKER_01 4:33

You know what I mean? Yeah. Can you picture it? Yeah. Yeah.

SPEAKER_00 4:36

You know, I've I think I've only seen that movie once 'cause it scared me as a child and I never saw it again.

SPEAKER_01 4:42

Well, I mean I can understand that. Yeah. This is the Reese's pieces. Isn't that what scared you?

SPEAKER_00 4:47

No, it was it was actually um the people in suits at the end. Right. That scared me.

SPEAKER_01 4:54

Yeah, I can see that.

SPEAKER_00 4:55

And then there's also a movie with with Angela Houston called The Witches. That scared me as a kid, and my brother was babysitting one time. Shout out to my brother Eric. So rude. He made me watch it while he was babysitting, and I was traumatized even more, and have yet to watch it again. And I have not watched the remake with Ann Hathaway, but I digressed.

SPEAKER_01 5:16

Oh, that that's a remake of that. Okay. I guess I didn't know that.

SPEAKER_00 5:19

Yes. Okay. So the condition that they were um seeing was called Focomelia. Focomelia. My apologies. Focomelia.

SPEAKER_01 5:30

Focomelia.

SPEAKER_00 5:32

It was a rare birth defect where limbs failed to develop properly. That sucks. So these babies were known in the media as thalodomide babies, though at first no one knew the cause. So physicians, the sudden increase in these cases were a little unsettling. Right. Birth defects were extremely rare, but now hospitals were seeing them again and again. Jeez. So pediatricians were comparing notes, and obstetrician try to identify patterns. Some wondered if it was environmental, perhaps radiation or pollution or an unknown virus.

SPEAKER_01 6:11

Right.

SPEAKER_00 6:12

But cases kept appearing.

SPEAKER_01 6:14

So you said over in the UK, this is mainly where you're talking about right now. Did these things, because you said it was sold in several countries. Did these same things happen in those other countries as well?

SPEAKER_00 6:27

Yes. And I will get to a little bit more specifics on that starting right now.

SPEAKER_01 6:30

Oh, okay.

SPEAKER_00 6:32

These cases weren't just isolated to the UK. Germany had a wave of these uh births. So did um Australia, Canada, and parts of Asia.

SPEAKER_01 6:44

Wow.

A Surge Of Rare Birth Defects

SPEAKER_00 6:44

And doctors started realizing Excuse me. Thousands of families were suddenly facing these heartbreaking circumstances with babies born with missing or malformed limbs, damaged ears, heart defects, or internal organ problems. Right. And these parents were confused and devastated. I would imagine. And mothers were like, What did I do wrong? And it's like, it's not you. Well. But no one could answer. We we they didn't know. Okay, so the mystery began unraveling when a few researchers started looking closely at what the mothers had taken during pregnancy.

SPEAKER_01 7:25

Which makes sense. You would obviously want to look through that because clearly something's going in them, and then something abnormal is coming out of them. So there has to be a correlation there. Yes.

SPEAKER_00 7:38

So one of the first physicians to connect the dots was a German pediatrician named Vitakoden Lenz.

SPEAKER_01 7:46

Vicodin?

SPEAKER_00 7:47

Vidokind. Sorry, Vidokind Lens.

SPEAKER_01 7:50

Vidokind, what's his last name?

SPEAKER_00 7:52

Lenz, L-E-N-Z.

SPEAKER_01 7:53

Oh, okay.

SPEAKER_00 7:54

Vidokind Lens.

SPEAKER_01 7:56

That was Germans, man. I know. Wild names. Wild.

SPEAKER_00 8:00

So as he interviews families, he begins to notice the same pattern that the mothers are starting are taking the same medication earlier in their pregnancy, and that was the thalodomide.

SPEAKER_01 8:13

Right.

SPEAKER_00 8:13

So another doctor in Australia named William McBride noticed the same pattern independent like independently but at the same time.

SPEAKER_01 8:21

So not a not a corresponding study, just he noticed it in Australia, he noted and noticed it in Germany. Exactly at the same time. Yeah. Okay.

SPEAKER_00 8:30

So the more cases this they studied, the clearer the connection became. Right. When pregnant women took uh phthalodomide during a very specific window of early pregnancy, roughly between the third and eighth week of conception, the developing embryo could be severely affected.

SPEAKER_01 8:49

Huh.

SPEAKER_00 8:49

The narrow window was exactly when limbs, ears, and other structures begin forming. Makes sense. Phalodomide interfered with the growth of tiny blood vessels that embryos need during development. Okay. So without these blood vessels, tissue couldn't grow properly. Yeah. Arms might never form, legs might st stop growing halfway, ears and eyes could be damaged.

SPEAKER_01 9:16

So you said some of them just had like hands out their shoulders, if you will. When do hands start growing?

SPEAKER_00 9:25

I don't know.

SPEAKER_01 9:26

Isn't that seems to be a good thing?

SPEAKER_00 9:27

Yeah, because it's yeah, it seems like arms and then hands, but well, you know, yeah, makes the sense and whatever.

SPEAKER_01 9:32

But like I remember seeing the ultrasounds of my kids, and it's like, hey, look at those little little hands. Yeah. That's just wild that it was such a specific time. But it makes sense if that's when those things start to develop.

SPEAKER_00 9:43

Yeah.

SPEAKER_01 9:44

I could see how that would severely fuck it up.

SPEAKER_00 9:46

So I mean, if they were taking the drug during the arm development stage and then they stopped taking it, or it went past the arm development stage to the hand development stage, and then that's when those hard to say, but it's just kind of weird. I mean, I'm a doctor, but what?

SPEAKER_01 10:05

Let's move on.

SPEAKER_00 10:07

So, in some cases, just one or two pills during that window of time could cause permanent changes to that fetus. Wow. Yeah.

Global Pattern And Medical Clues

SPEAKER_01 10:19

Did they did they notice, did you come across at all um after that window if the the mother was taking that was were things fine then? Or did you not come across? I did not come across that. That's all right.

SPEAKER_00 10:32

Yeah. That would be interesting though.

SPEAKER_01 10:35

Well, yeah, because I mean if it's such a specific window for these certain things.

SPEAKER_00 10:40

And like for many people, morning sys morning sickness continues throughout the pregnancy, not just that first trimester.

SPEAKER_01 10:49

Right. Besides the extreme high blood pressure for Sarah, she was very lucky and did not have morning sickness for either child of ours. So she got she got lucky. Yeah. And it's a good thing she didn't take that.

SPEAKER_00 11:03

Saladomide.

SPEAKER_01 11:04

Saladomide. Because I wouldn't want to see Vesper walking around with feet coming out of her pelvis or whatever.

SPEAKER_00 11:11

No.

SPEAKER_01 11:12

Her hips. That'd be weird.

SPEAKER_00 11:15

So by early 1960s, the evidence had become undeniable.

SPEAKER_01 11:20

Sure.

SPEAKER_00 11:20

The drug that had been marketed as a sleep, a safe sleeping aid was was responsible for one of the largest medical disasters of the 20th century. Wow. So estimates vary, but experts believe that more than 10,000 babies worldwide were born with uh thalodomide-related deformities.

SPEAKER_01 11:41

That's crazy. 10,000?

SPEAKER_00 11:43

And only about half survived inf infancy.

SPEAKER_01 11:46

Oh, really? I was gonna ask, are there yes?

SPEAKER_00 11:49

So many died from internal organ complications, um, heart and digestive defects. Okay. And those who did survive faced enormous challenges. Um children grew up without arms and learned to use their feet to eat, write, perform everyday tasks. Right. Others relied on prosthetic limbs, and many underwent dozens of surgeries throughout childhood.

SPEAKER_01 12:13

Sure, it's just to try and correct anything they obviously possibly could. That would make it really hard to drive.

SPEAKER_00 12:20

Yeah.

SPEAKER_01 12:21

The old ten and two.

SPEAKER_00 12:24

So despite these hardships, many survivors did live on to live remarkable lives.

SPEAKER_01 12:30

Okay.

SPEAKER_00 12:31

Um, adapting in ways that most people couldn't. Yeah. Really?

SPEAKER_01 12:36

Yeah.

SPEAKER_00 12:36

So the tragedy also exposed some major flaws in how medications were tested and approved. Some investigators looked back at the original development development of a thalodomide and they discovered something. The drug had been tested on animals, but researchers had not adequately studied its effects on pregnant animals.

SPEAKER_01 12:57

Oh, sure.

SPEAKER_00 12:58

So the impact on fetal development had gone unnoticed.

SPEAKER_01 13:02

So do you think if they did it? I don't know what kind of animals they mostly test on. If it's a chimp or something.

SPEAKER_00 13:09

Yeah.

SPEAKER_01 13:10

Chimp born without arms, that'd be weird as fuck.

Linking Thalidomide To Fetal Damage

SPEAKER_00 13:12

Yeah. But um the drug manufacturer, sorry, the drugs manufacturer, a German um pharmaceutical company called Kemi Grunthal. That's what it is.

SPEAKER_01 13:26

I like it.

SPEAKER_00 13:27

Um, had promoted um thalodomide aggressively.

SPEAKER_01 13:30

Sure, because they want to make money.

SPEAKER_00 13:33

In many countries, it was sold under dozens of brand names and widely distributed throughout clinical trials. And once the link to birth defects became clear, governments put rushed to pull the drug from the market. Okay. And by late 1961, thalodomide was being uh withdrawn across the world. Wow. In one country, something unusual had had happened in the United States. Yes, the drug had been submitted for approval to the Food and Drug Administration.

SPEAKER_01 14:02

Yeah.

SPEAKER_00 14:03

A pharmacologist named Frances Oldham Kelsey was assigned to review the application. As she studied the company's research data, she noticed gaps and inconsistencies. Oh. The safety study seemed incomplete. Okay. Reports of nerve damage in patients raised additional concerns. So instead of proving approving the drug quickly, as many would have expected, Kelsey repeatedly asked the company for more evidence.

SPEAKER_01 14:34

Okay.

SPEAKER_00 14:35

Pharmaceutical representatives grew frustrated, and of course, they pushed for her approval. Thalodomide was already selling well overseas, and the company hoped to capture the American market, but Kelsey refused to sign off on it. So her um insistence on stronger safety data meant that thalodomide never received widespread approval in the United States. That's crazy. Only small quantities were distributed through clinical trials, which limited its impact. Of course. So when the global disaster became known, her decision was recognized as a life-saving act of scientific caution. Sure. In 1962, President John F. Kennedy awarded Frances Kelsey the President's Award for Distinguished Federal Civilian Service. That's awesome. Her refer refusal to rush approval had spared thousands of American families from the tragedy unfolding elsewhere. And the thalodomide disaster changed medicine forever. Public outrage pushed governments to strengthen drug safety regulations. Okay. And in the United States, new laws required pharmaceutical companies to both prove safety and effectiveness before drugs could reach the market. Good. And clinical trials became much more rigorous.

SPEAKER_01 15:56

Okay.

SPEAKER_00 15:57

Testing during pregnancy also became a critical area of research.

SPEAKER_01 16:02

So is that that's a common practice these days since since this happened, basically? Yeah. I mean, you it makes sense.

SPEAKER_00 16:09

Yeah. Modern drug approval systems with their multiple trial phases and strict oversight owe much to the lessons learned from this uh thalodomide. Um words.

SPEAKER_01 16:25

Words are tough.

SPEAKER_00 16:26

Thalodomide disaster.

SPEAKER_01 16:28

Let's go with that.

SPEAKER_00 16:29

Yeah. Despite its devastating history, thalodomide did not disappear.

SPEAKER_01 16:37

Imagine that.

Human Impact And Survivors’ Lives

SPEAKER_00 16:38

Years later, researchers discovered that the drug had powerful anti-inflammatory and immune modulating effects. Okay. So under extremely strict controls, it began to be used to treat certain diseases, including complications of leprosy and a type of blood cancer known as multiple myeloma.

SPEAKER_01 16:59

Okay.

SPEAKER_00 16:59

Today, thalodomide and related drugs are still prescribed in carefully monitored programs where pregnancy prevention is strictly enforced. Wow. The same medication that once caused the worst pharmaceutical tragedies in history now helped treat life-threatening illnesses.

SPEAKER_01 17:16

That's crazy.

SPEAKER_00 17:17

It is a reminder that medicine often walks a strange line between this disaster and discovery. Yep. For the families, uh thousands of families affected, the story of thalodomide was not just a historical left, and it was part of their lives written into their bodies, into their experiences. Right. Children who were born with missing limbs grew up to become artists and athletes, activists and advocates, all A's for disp disability rights. And many survivors have spoken publicly about their lives, determined that the world would never forget the lessons of the past. And that is the story of the thaladomide babies.

SPEAKER_01 17:56

That's wild.

SPEAKER_00 17:57

Isn't it?

SPEAKER_01 17:58

That's just weird that, like, I mean, knock on wood that I have all my digits and arms and limbs and my kids do and so on, but damn, I couldn't imagine. And like, great for them that you know they could find a life afterwards. It was such struggles early on in life, but poor uh what'd you say, half didn't even make it through infancy, right? That's sad.

SPEAKER_00 18:20

It is, yeah.

Regulatory Failures Exposed

SPEAKER_01 18:20

It's a lot of kids to have die because a drug company, and you know how I feel about drugs, yeah, you know, stuff like that. I I don't even really like taking ibuprofen or whatever if I don't have to. So I mean, I know there's ones out there that help people, and that's great, but man, I don't like how like you sit down and if you put on normal TV, it's like 40% of the commercials are pushing these fucking drugs for oh hey, you got a little blotch on your skin. We can make it 70% better, right? Or you could just be like, I don't care. But the side effects can lead to death, suicide, and you know, all these other just ridiculous, you know. And I the one that I love always on those commercials. If you're allergic to I know you're drunk here, do not well, no shit. It's just like I'm allergic to bees, sting me bee. Yeah, no, no, obviously not, but it's just there's so many like side effects from this stuff, and I know it's the funny thing is about the side effects, it could have happened once, but then they have to say it. But it's like, good lord, yeah, if we just all wouldn't care. Just kidding. If we were all just healthy, well, I mean I know I do unhealthy things, unfortunately, but I'm not sitting there putting hard drugs or anything like that in my body either. But you know, unfortunately, people have to go through shit. Yeah, it happens, and sometimes some drugs help, and that's great. Um, but uh yeah, if we could all just be healthy, that'd be amazing. And we're all going for world peace, too.

SPEAKER_00 19:59

Absolutely.

SPEAKER_01 20:00

Welp.

SPEAKER_00 20:00

I suppose.
