His successful business allowed him eventually to indulge his youthful passion for art, first as a collector and subsequently as a patron, by opening a gallery next to one of his chemist outlets at 84 Sloane Avenue in Chelsea.
[10] The gallery became known as a pioneer of group and solo shows of recent art school graduates, including graduates of the nearby Royal College of Art, as well as artists from the British Commonwealth and established Polish émigré artists.

[18] The Grabowski was one of several noted contemporary art exhibition spaces initiated by émigré Poles in London.
