Twenty years ago this June, a software entrepreneur named Phillipe Kahn witnessed his daughter Sophie’s delivery. This milestone moment also inspired the birth of a new technology, according to Slate—an invention that’s credited by many as the very first camera phone.

Eager to share pictures of his newborn with the world, Kahn raced to his car to grab his soldering iron, and used it to fuse a Casio QV-10 digital camera together with a Motorola Startac flip phone. The camera was connected to a laptop, and the computer was connected to Kahn’s home server.

The jerry-rigged contraption was primitive, but effective. Kahn snapped a photo of Sophie and sent the picture to around 2000 friends, family, and business connections. Soon, the father's inbox was flooded with messages, asking him how he’d managed to capture—and share—the image mere minutes after his daughter's birth.

Hear the story in Kahn’s own words below, recounted in a short documentary by creative studio Conscious Minds.
