"(Piet Mondrian's) comment was: 'You have a very strong inner rhythm. You must never lose it'. Then we moved on. Piet Mondrian had said something quiet beautiful to me. Hofmann was also excited and enthusiastic about what I was doing at this time [c. 1938] but his comment was: 'This is so good that you would not know it was done by a woman'. His was a double-edged compliment. But Mondrian’s evaluation rides through beautifully."
