> In 1827, Niépce traveled to England to visit his brother. While there, with the assistance of English botanist Francis Bauer, he presented a paper on his new invention to the Royal Society. His findings were rejected, however, because he opted not to fully reveal the details, hoping to make economic gains with a proprietary method.

And in doing so joins the graveyard of many promising technologies that were left by the wayside of history because the inventor thought more about locking people out than getting them on board.

I saw this one time. It wasn’t a whole lot to look at (even in a darkened booth, it was only barely discernible) but that only added to the overall spooky effect of looking back visually into the past to the first instant a visual representation was captured. I would recommend visiting it if you’re ever on or near the UT campus.
