The Hungarian artist Vera Molnár, who died last December at 99, was already producing abstract paintings in the 1940s. In the 50s she moved on to combinatorial images, which used mathematics to construct shapes. Math fascinated Molnár, and she eventually gained access to a computer in a Sorbonne research lab. Molnár taught herself early programming language and used a plotter to create graphic drawings. “My life is in squares, triangles, lines,” she once said. Centre Pompidou’s retrospective celebrates this female pioneer of computer-generated art. —Elena Clavarino
