Who says modern can't be romantic? Knoll just unearthed a trove of love letters exchanged between iconic designer Eero Saarinen and his wife, writer Aline B. Saarinen. Filled with pet names and poems, the letters reveal an intimate side to the architect that was sometimes absent from his designs.

We've reproduced the list in full, along with a few of our favorite images from Saarinen's career.
