Solomon “Sol” LeWitt (September 9, 1928 – April 8, 2007) was an American artist linked to artistic movements including Conceptual art and Minimalism. LeWitt came to fame in the late 1960s with his wall drawings and sculptures, but was prolific in a wide range of media including drawing, printmaking, photography, and painting. In the 1980s, after a trip to Italy, LeWitt started using gouache, an opaque water-based paint, to produce free-flowing abstract works in contrasting colors. These represented a significant departure from the rest of his practice, as he created these works with his own hands. LeWitt’s gouaches were created in series based on specific motifs such as Irregular Forms, Parallel Curves, Squiggly Brushstrokes and Web-like Grids.
