Who was responsible for the ultimate design of the (now) standard electric
box cover plates for
switches and plugs?   I've been ever curious since a lecturer about
proportions pointed out that we could find common examples of Golden Ratios
all
around us in those covers as well as Credit Cards.  He proved it to us by
carefully measuring them, but couldn't answer the history of industrial
design question about WHO made the executive decisions.

cp in bc,
(still proportional, since my specialist surgeon friend pointed out that the
neighbouring bones in each of our fingers are in Golden Ratio proportion to
each other ((he says they use that information in surgical reconstructions
of hands)).   No wonder the credit card folks chose that ratio to appear a
natural fit for our hands, but who was at the design table?  Were they
Masons?)
