Behind the Scenes Minis: Fitz Hugh and Sleepytime

16th-century Swiss physician Paracelsus was frustrated with established medical practice and academia and he was sometimes on the lam because of his beliefs. He wrote at length about the idea that items in the natural world carried “signatures” in their appearance that could tell you visually how they could be used medicinally.

Paracelsus and the Doctrine of Signatures

Hi, Stuff You Missed in History Class listeners! We're excited to share with you a sneak peek at iHeartPodcasts' latest release, Hoax!
 
Hoax!: Why do so many people believe things that aren’t true? In an era when claims of “fake news” come as naturally as breathing, and social media allows lies to spread and multiply like viruses, the question feels more relevant than ever. From the teenage girls who convinced Sir Arthur Conan Doyle that fairies were real in the 19th century to “Balloon boy” in 2009, Hoax! will explore the most audacious and ambitious tricks in history. Along the way, we’ll uncover the reasons people let themselves be fooled and how we can live our lives and engage with the media with a more critical eye. Co-hosted by Noble Blood’s Dana Schwartz and pop culture writer Lizzie Logan, we’ll bring you stories of pranks and grifts throughout history so big and bold they make us question why we believe what we believe in the first place.
 
 
 
Listen to Hoax! on the iHeartRadio App or wherever you get your podcasts!
