I think I'm 'someone' :-)
According to my book: "Oscar Reuterswärd, Omöjliga figurer" the Opus 1 from
1934, is "the first known case in Art History when an artist consciously
makes an 'impossible' design", but as the book is written by OR himself, I
wouldn't put too much trust in that...
Especially as on the opposite page, there is an example by William Hogart
with the caption "Whoever makes a design without the knowledge of
perspective will be liable to such Absurdities as are shewn in this
Frontispiece", where Hogart obviously made an impossible design consciously.
It's not geometrical, though.
OR is calling the collection "Perspective Japonaise", which might indicate
an influence from Japan or, on the other hand, may just be a name on the
perspectiveless perspective...
Penrose was probably the first one _publishing_ such pictures (1958).

Judging by the name 'Opus2b', it would be very early, probably around '40,
but we'll never know...
He was born 1915, but didn't 'show up' on exhibitions until 1960 (according
to the book), so the dates of previous designs might be a little fuzzy.

At the Linköping University, there's a physical model, built 1981, connected
everywhere, that looks exactly as one of OR's designs - a variation of the
Escher Monks in Stairs (that's not the name, but describes the picture, I
don't want't to run and fetch the Escher book too, just to check the name).
Of course, it only works in _one_ viewing angle, from all other directions
it looks all wrong.
