As you read about Lynne Drexler you come to have a great respect for her and her work. Born in 1928 and having schooled under Hans Hoffman and Robert Motherwell, she found her own way and stuck with it. Her way was to break down the picture plane into smaller areas of color with brush strokes of all sizes and even dots. This was definitely a new take on pointillism, where the realism was starting to matter less and the appreciation for the individual pieces of the painting took center stage. The word pointillism is never mentioned when describing her work and she doesn't seem to have considered herself to be involved with the genre, but this certainly is a fore runner to the postmodern pointillism of today. You'll especially want to see her work in the Collection at the Portland Museum of Art.
Always interested in nature and landscapes, she later incorporated stylized organic forms into her work, as in the painting above. These have a wonderful harmony to them and just seem to make sense.
The top image is from the Portland Press Herald, which has more images and a nice article about her. Another good read (short) with images is the Jameson Art Group.
This image, "Jomo's World" 1966 Oil on canvas, 22" x 22", is from the Anita Shapolsky Gallery.
She's also represented by the Thomas McCormick Gallery
and the Maine Art Collectors.
