September's Artist of the month is Piet Mondrian.  He was a Dutch Neo-Plasticist painter.  Which means It is a rigid form of Abstraction, whose rules allow only for a canvas subsected into rectangles by horizontal and vertical lines, and colored using a very limited palette. 

He lived from 1872-1944.
