The Willet Hauser Studios association with Jacob Landau began when he was commissioned by Keneseth Israel Reform Synagogue in Philadelphia to create paintings that were to be interpreted into stained glass windows. The congregation had conducted a search for a well-known artist to design the windows. Landau’s work deals with the universal concerns of Turmoil, Symbiosis, Love and Grief. His depictions of the scriptural prophets exhibited in his paintings for these windows bring them into the present. He was called a reformist, a visionary as were these prophets.
In that Landau had no previous experience in designing stained glass, Benoit Gisoul translated his drawings into original cartoons and the Willet Hauser Studios fabricated the windows.
