This article contains a series of new proposals as well as corrections that its authoress, occupying herself for a period of over forty years with the art of this Polish painter and graphic artist (1880-1970) who lived in Paris on a permanent basis from 1903 onwards, wishes to contribute to the current state of research into this artist. The first part of this article comprises a critical assessment of the most recent proposals for dating graphic works by Brandel together with the handwritten catalogues compiled by the artist himself. The second part of the article comprises a discussion on the place Konstanty Brandel’s creative work occupies among the main currents in European art during the period he was active. Here, specific attention is given to the painting and graphic art of German Expressionism, this being an area of Brandel’s artistry thus far ignored by specialists which the authoress wishes to point out while postulating the necessity of detailed research in the future.
