Sass Gábor munkássága. Egy gazdasági géptan tankönyv születéstörténete

Abstract

This article examines the work of Gábor Sass, a mechanical engineer, as a textbook author and his textbook on Economic Mechanics. We draw heavily on the author's papers, a valuable part of the Collection of Agricultural History Papers of the Hungarian Agricultural Museum and Library. The collection of documents includes the review reports on the textbook, the author's reply, the author's correspondence with the agricultural machinery companies, and his correspondence with his co-author, Béla Molnár, in 1935 and 1936. Information on the actual use of the textbook in schools was gathered from contemporary school notices. For the biography of Sass, we consulted Gyula Réz's 1989 book, and for our knowledge of the history of machinery, we consulted János Estók's 2001 volume. Our research is interdisciplinary since it enriches our understanding of agricultural history, the history of agricultural education, and the history of machinery and mechanical engineering, in addition to school history and textbook history.
