We talk a good bit about the Duchenne smile in our podcast episode "The Science of Smiles," so let's take a look at the 19th century experiment in question via this image gallery. Here we see Dr Guillaume Duchenne de Boulogne, a French physician and a pioneer in electrophysiology, demonstrating the appearance of laughter by electrical muscle stimulation.

He wrote for the smallest of small-town newspapers before finally becoming a full-time science writer and podcaster. He’s currently a senior writer at HowStuffWorks and has co-hosted the science podcast Stuff to Blow Your Mind since its inception in 2010. In his spare time, he enjoys traveling with his wife Bonnie, discussing dinosaurs with his son Bastian and crafting the occasional work of fiction.
