Intrigued, Alday reached out to Cox, who now owns his own UX and UI company, to find out more. Here's how Cox responded:

You've done your homework and found the right guy. I designed that symbol many years ago as a "container" for contextual menu choices. It would be somewhat equivalent to the context menu we use today when clicking over objects with the right mouse button.

Its graphic design was meant to be very "road sign" simple, functionally memorable, and mimic the look of the resulting displayed menu list. With so few pixels to work with, it had to be very distinct, yet simple. I think we only had 16x16 pixels to render the image. (or possibly 13x13... can't remember exactly).

Interesting inside joke... we used to tell potential users that the image was an "air vent" to keep the window cool. It usually got a chuckle, and made the mark much more memorable.

It's been nice to see that so many of our designs from those early pioneering years have stood the test of time and become ubiquitous symbols in our UI's.

I wonder if Cox could have imagined that his icon would become as familiar as a stop sign, as a young designers in the early 1980s. Thanks to Alday, we can now add the hamburger to a growing list of historic UI mysteries solved. Previously: the mouse arrow, the broken image icon, and the pan hand. [Evernote]
