Can you name the earliest SLR?

Very interesting article (to me at least). Did not know about this camera.

I agree and interesting article indeed. From a historical perspective however it was not the first SLR. That distinction goes to E. W. Smith for his Monocular Duplex camera. Quite different than what we perceive today.
