Born in Warsaw in 1950. In 1968 he passed his secondary school leaving examination at the French secondary school in Warsaw. In 1968–1972 he studied art history at the Warsaw University, from which he graduated with a master’s thesis about iconography of Renaissance Venetian painting (his advisor was Prof. Dr. Jan Białostocki). In the years 1971 and 1972 he repeatedly held scholarships and did research at the Fondazione Cini in Venice. In 1971 he was chosen by Henryk Stażewski (the laureate of the “Gottfried-von-Herder Preis” in 1971) to be awarded the scholarship of the Herder Prize. From 1972 he continued studies in art history at the Vienna University. In 1973 he participated in the CIHA International Congress of Art History in Granada (Spain). In 1976, at the Vienna University, he defended his doctorate which treated Leon Chwistek and his “zones theory” in painting. During the years 1975 and 1976 undertook further studies and research-stays at the Fondazione R. Longhi and the Villa I Tatti (Harvard University) in Florence. As their result he published articles on Donatello, Titian, Lorenzo Lotto, Tintoretto, Padovano and Algardi. In 1977 he was awarded Prof. Karolina Lanckorońska’s (Fundatio Lanckoroński) scholarship to pursue further research on the art of Italian Renaissance.

In 1973 he participated in the CIHA International Congress of Art History in Granada (Spain), and again in Bologna in 1979.

After the CIHA International Congress of Art History in Bologna in 1979, together with an international group of scholars (André Chastel, Jan Białostocki, Federico Zeri, W. Roger Rearick, Hermann Fillitz) he founded the International Institute for Art Historical Research IRSA (Istituto per le Ricerche di Storia dell'Arte) with headquarters in Venice and became its director. Next year, in 1980 he started publishing a scholarly art-historical journal entitled ARTIBUS ET HISTORIAE, of which he has been the editor until now. IRSA Publishing House has hitherto published over 600 papers, written by scholars from most of European countries and many of the world.

Roger Rearick, Hermann Fillitz) he founded the international Institute for Art Historical Research ( Istituto per le Ricerche di Storia dell’Arte) with headquarters in Venice and became its director. A year later, in 1980 he developed and began publishing a scholarly art-historical journal entitled ARTIBUS ET HISTORIAE which he has been the editor to this day. IRSA Publishing House has hitherto published over 600 papers and books, written by scholars from most of the European countries and many others from around the world.

In 1990, in Vienna, he established a gallery of fine art named “Apollo Art Galleries”. From 1980 he worked on building a collection of fine art for Barbara Piasecka Johnson. Part of this collection important was shown in the exhibition, “OPUS SACRUM”, held at the Royal Castle Warsaw and co-organized by Dr Grabski and Prof. Andrzej Rottermund.

Dr Grabski has developed special ties with Japan, where he co-created two great museum collections of European art, namely that of Marubeni and Takeuchi. Since 1992, he has held lectures as a visiting professor at the Art History Department of the Sendai University (Tohoku Daigaku) focusing on Raphael, Titian, Tintoretto, Van Dyck among others. In 1996 a branch of IRSA, dealing with mutual relations of European and Asian art, was established at the Sendai University (dir. Prof. Hidemichi Tanaka). Since 2008 he is an adviser of the museums in Cina (Beijing, Shanghai), where he organizes also art exhibitions.

He has been interested particularly in his scholarly research in the work of Donatello, Giorgione, Titian, Lorenzo Lotto, Paris Bordone, Tintoretto, Caravaggio, Caroselli, Algardi, Rubens, Van Dyck, Artemisia Gentileschi, Vermeer van Delft, and Rembrandt. The main area of Dr Grabski’s interest is, however, modern European art.
