Eva Slater studied art and life drawing in Berlin, Germany (where top photo was taken) as well as Art Center in the late 1940's and early 1950's. Although she went on to paint landscapes and abstract hard-edge paintings, she had a solid traditional art training, which is one reason her later work was so good - it had a strong foundation. Slater's feeling for line and a more minimalist approach can be seen in her early works because the desire for simplicity was a part of her personality. A number of the abstract painters working in Slater's time (1950's and 60's), like Slater, had a good solid figurative background and it made for a more aesthetically sound abstract paintings. They really knew what they were doing back then.....
I have been studying and creating art all my life and am married to figurative artist Harry Carmean - we have been making art together for forty years and so am sharing some of what we have done in this and related blogs.
