Twenty years after the last museum exhibition of his work, MASI Lugano is dedicating an extensive retrospective and publication to Richard Paul Lohse. This ambitious project underlines the importance of Lohse's work and the central position he occupies in the international art world with his painting. With a selection of more than forty paintings from the four key decades of his artistic career, from the 1940s until his death, the authors shed light on fundamental elements of his rigorous methodical approach as well as historical events, social utopias, and Lohse's confidence in the expressive power of color.
