From physicists to photographers developing their plates, Naturalist painters recorded the science and technology of their time.
Unlike Impressionism, which spread relatively slowly, Naturalism was prominent in the Salon, so spread across Europe and North America like wildfire.
The very large Paris Salon of 1883 introduced the public and critics to a new and growing movement in painting. It wasn’t Impressionism or Post-Impressionism, though.
From 1880, artists concentrated on social aspects of work. They questioned whether young children should be at work, and the role of the worker in society.
