The Russian "Sport" was the first SLR, followed closely by the initial
Exakta models.  But both lacked a prism and you viewed the camera as you
would a Hasselblad or Rolleiflex TLR with their WLF's.  In that since, the
Russians deserve the credit for the first SLR of ANY kind.

Hubert Nerwin, Chief Designer at Zeiss Ikon, was the first to conceive of
an SLR with a penta-prism to allow horizontal viewing with a properly
aligned image.  He thought this up around 1937, but the Contax S, due to
the War, did not appear 'til '49, after Nerwin had moved to the US and was
finishing work on that "Contax on Steroids", the Combat Graphic 70.
