The 19th Century
The end of the industrial revolution and the birth of scientists
The Industrial Revolution began around 1760 and ran through the 1840's. Then began the birth of the profession of science. Louis Pasteur, Charles Darwin, Michael Faraday, Thomas Edison, and Nikola Tesla were all products of the 19th century. And, in 1839, the first camera was commercially introduced.
As a result of the commercial camera, we have the first photographic record of the sights of the lives and lifestyles of a century.
