A historical figure that I would bring back to life would be Louis Daguerre. Louis Daguerre was a French artist and photographer. He is particularly well-known for his invention of the daguerrotype process of photography, an early photographic type. Therefore, he is known as one of the fathers of photography.
I would imagine his favourite app would be <em>Instagram</em>. This is because the app would allow him to see the enormous progress that photography has made, and the important role that it has on our present lives.
