In the beginning, there were no cubicles. It wasn't until 1968 that the cubicle was invented by Bob Propst of office furniture company Herman Miller.

Originally viewed as an improvement over the open office plan, Propst’s design was adapted in order to cram more employees into smaller spaces. 

Probst came to regret his invention; “They make little bitty cubicles and stuff people in them. Barren, rat-hole places...”

Thanks, Bob.
