Nadir Afonso (December 4, 1920 – December 11, 2013)

Nadir Afonso, (December 4, 1920 – December 11, 2013) was a geometric abstractionist painter. Formally trained in architecture, which he practiced early in his career with Le Corbusier and Oscar Niemeyer, Nadir Afonso later studied painting in Paris and became one of the pioneers in Kinetic art, working alongside Victor Vasarely, Fernand Léger, Auguste Herbin, and André Bloc.

As a theorist of his own geometry-based aesthetics, published in several books, Nadir Afonso defends that art is purely objective and ruled by laws that treat art not as an act of imagination but of observation, perception, and form manipulation.
