Considered to be one of the pioneers in Pointillism along with Georges Seurat. The birth of the Pointillism school is often listed as 1886.
In a previous lifetime I used hand-held radios to communicate with other people in a noisy (+85 dBa) factory. Simple commands, repeated and then with the other person repeating back what they think they heard "drilled through" the noise.
Pointillism is the visual equivalent.
