To truly understand how Janusz Korczak revolutionized the "recording of children’s voices", one must trace the technical apparatus he utilized. The institutional implementation of stenography during the conferences of Mały Przegląd was not a late, spontaneous editorial experiment. Its methodological foundation was laid a decade earlier.
Korczak formally mentions stenography for the very first time in his seminal work How to Love a Child: The Child in the Family (Jak kochać dziecko: Dziecko w rodzinie), published in 1919. In this book, Korczak draws a direct parallel between the meticulous diagnostics of psychiatry and the future of pedagogy:
"In psychiatric clinics, the stenographer records the monologues and conversations of patients; it will be the same in the future in pedagogical clinics. Today we have only material: a catalog of children's questions."
For Korczak, stenography was the ultimate anti-censorship tool—a way to outrun the swiftness of children's speech and preserve it without the intrusive filtering, stylization, or moralizing of an adult hand. This deep methodological commitment is precisely why Korczak later hired Igor Newerly to be his private secretary and the editor-in-chief of Mały Przegląd. Newerly’s primary, indispensable asset for the job was his fluent mastery of stenography, allowing him to act as the objective, rapid human recording device for the children’s parliament.
