An Art History lesson.

Pieter Cornelis "Piet" Mondrian; (March 7, 1872–February 1, 1944), was a Dutch painter. After a strictly Protestant upbringing, in 1892, Mondrian entered the Academy for Fine Art in Amsterdam, already qualified as a teacher. He was an important contributor to the De Stijl art movement and group, which was founded by Theo van Doesburg. He evolved a non-representational form which he termed Neo-Plasticism. This consisted of a grid of vertical and horizontal black lines and the use of the three primary colors.

Paul Jackson Pollock (January 28, 1912 – August 11, 1956) was an influential American painter and a major figure in the abstract expressionist movement in New York. In October 1945, he married the artist Lee Krasner. During his lifetime, Pollock enjoyed considerable fame and notoriety. He was regarded as a mostly reclusive artist, but had a volatile personality and struggled with alcoholism all of his life. He died at the age of 44 in an alcohol-related, single-car crash. In December 1956, he was given a memorial retrospective exhibition at the Museum of Modern Art (MoMA) in New York City.
