From the memories of contemporaries

“[...] it was difficult to find another face like his – the forehead seemed to be going backwards, as the nose was like an eagle’s beak pointing forwards and strangely formed. The staring eyes were huge, the lower lip big and protruding, and these specific features meant an imprint of that face remained in the memory of anyone who had seen it.” (A. Szemesz, 1844, p. 211–212)

“[...] there was no one in Vilnius who had not seen him going or riding along the Antakalnis road or playing billiards at the “Polska kawa” cafe in the Big Street of the Old Town. And there was no one who had not seen the portraits he had drawn in huge numbers and with such distinctiveness.” (A. Szemesz, 1844, p. 211)

“By nature, he had a vivid and restless mind and knew a few languages, so he was able and liked to use rich sources of European science. There were few art and literature publications, especially those widely known, that had not been used to some extent by Rustem [...]. His reasoning was always based on common sense, as he was not only especially enthusiastic like any artist, but had the cold blood of the perfectly erudite.” (W. Smokowski)

“[…] He was a virtuous, modest and especially civilised man who was liked by everybody because of his sincerity and pleasant behaviour. In addition, he cared a lot about the well-being of his students.” (S. Jundziłł, 1909, p. 34–35)

“He liked the company of people and was witty and nice, so he was always welcomed into high society. Wearing his red fez on his head, he reminded one of his oriental descendancy.” (E. Rastawiecki)

“He was an unrivalled drawer and a very nice man.” (J. Frank, 1913)
