The gentlemen's clothing date the photos to the late 1940s or 1950s.

Yet the building(s) seems much more contemporary.
My first thought was religious sect, perhaps something akin to an early version of the Heaven's Gate cult http://en.wikipedia.org/wiki/Heaven'...eligious_group)
A bit far-fetched I know...but I'm known for my vivid imagination.

Like many of you at first blush this seems crazy but after googling "pyramid planetarium"
I discovered these structures are not uncommon! Take a look at this example at Texas A&M.
Now I see the hemispherical screen that I would expect.
So why the pyramid?
To protect the screen from the elements?
The screen must be pretty delicate.
If it is so delicate how does it hold its shape?
By positive air pressure!
Check out this
portable planetarium.

So, was Henry C Wilhelm a kook or visionary?
PS, thanks for all the fascinating posts everyone.
