Multi-Storey Car Park

Ever wondered who designed the multi-story car park?

Nope, neither had I :)

Until I happened across Popular Science magazaine, for April 1921 (I'm spending some time catching on reading - there's a bit of a backlog).

We're told that Fernand E. d'Humy has patented a throughly practical plan.

The key elements are that "The floors and ceilings are not on a line, for the floor of one corresponds with a point midway between the floor and ceiling of the other. Thus an inclined passage . . . leads only half a storey at a step."
