The Mid Century Vault

Currently Playing: 097 Pneumatic Tubes: The Secret Air Network That Built the Modern World

Imagine a world where information traveled at 30 MPH beneath the city streets, powered by nothing but air. Long before email, fiber optics, or the internet, major cities like New York, London, and Paris relied on a massive, hidden network of pneumatic tubes to keep the world moving. In this episode of The Mid Century Vault, your host Philip Mershon uncovers the incredible, steampunk history of pneumatic tube systems. From the underground mail tubes of the U.S. Postal Service to the bustling retail hubs like Marshall Fields and Sears Catalog distribution, discover how this "physical internet" revolutionized 20th-century commerce. We’ll explore why these glorious, art-deco systems vanished from our office walls, and where they are STILL being used today—from major hospitals like the Mayo Clinic to your local drive-thru bank and pharmacy. Did you know these systems were this massive? Do you work somewhere that still uses a pneumatic tube? Let us know in the comments below!
