E. Chwalewik (1873-1956) was a librarian, bibliophile, book historian, co-founder of the Society of Polish Bibliophiles. Chwalewik's book collection (numbering some 4,000 volumes, mainly on economics, history, literature) was partially burned during the Warsaw Uprising. "His works of documentation and exlibrisology became a model and reference for many later studies" (Wikipedia).
