Defined by a monolithic clarity, Tworkov progresses towards a reductive and structured process in his painting. Geometry becomes a spatial parallelogram creating variation upon variation of structure and gesture in the artist’s canvases during this decade. Through his tenure as the Chairman of the Art Department at Yale University (‘63-69) and active nationally as visiting artist, Tworkov becomes a much-sought-after teacher whose appeal to young people comes from his sense of moral purpose evident in the man and his work.
