First volume of three-volume city and statistical atlas by Lajos Illyefalvi, published in 1933. Collation: XII pages, 201 plates (including 1 fold-out), [3] pages. Plates contain a total of 214 maps and 926 diagrams. Final map serves as an index to the information throughout the volume, representing the administrative divisions within Budapest, as of 1933. Maps and diagrams printed in color and accompanied by legends and explanatory text. Atlas includes an introduction and an explanation on the administrative boundaries within Budapest, as well as a key to the index numbers found on certain maps and within the data of certain diagrams. Erratum appears at the end. All texts - as well as all maps and diagrams - appear in both Hungarian and German. Covers are linen-covered board; binding includes exposed blue cord. Authorship, title and imprint on front cover, in Hungarian, in navy blue. The atlas was unique at its time of publication “because it was the first representative album in Hungary which told about history, correlations and complexity using only the visual language of graphs, diagrams and thematic maps in exceptional quantity and quality” (Bátorfy). “Lajos Illyefalvi was born in Lajtafalu (now Potzneusiedl, Burgenland, Austria) in 1881 as Lajos Imre Janisch to an Evangelist family. In 1907 he changed his name to Illyefalvi (sometimes written as Illyefalvy) and graduated from the Science University of Budapest (the predecessor of Eötvös Loránd Science University). In 1908 he joined the Budapest Capital Statistical Office and served as the director of the Office from 1926 until his retirement in 1943. From 1929 on, he was a member of the International Statistical Institute. His main research fields were urban population and economics, and he was a pioneer in Hungarian statistical research of women in society. He served as the editor of several journals, most notably he was the editor of Bulletin of Statistics until his retirement. He died at 63 in April 1944. A székesfőváros múltja és jelene grafikus ábrázolásban (Past and Present of the Capital in Graphic Presentation) was published in 1933, Budapest székesfőváros áruforgalma (Trade Accounts of Budapest) in 1937, and A székesfőváros jelentősége hazánk anyagi és szellemi művelődésében (The Importance of the Capital City in our Country’s Material and Intellectual Culture) in 1940. The first volume, [Past and Present] came out in 1933 for the 60th anniversary of the merge of Buda, Pest, and Óbuda into Budapest. Illyefalvi writes in the [introduction] that the aim of the album was not just popularizing statistics but to help the interest of the scientific research: The graphic presentation gives some new perspectives for professionals, statisticians and economists, clarifies correlations, relations which can’t be read out from the numbers (p. II.). The two subsequent albums edited by Illyefalvi, published in 1937 and 1940, followed the first’s overall concept. In addition, the draughtsmen re-introduced 3D perspective visualizations and maps. Illyefalvi argued in the Introduction that with a three-dimensional method they could show more complex correlations and comparisons (Bátorfy).” For the second volume of the atlas [Trade Accounts of Budapest], please see Pub List No. 14246.000, and for the third volume [Material and Intellectual Culture], 14247.000.
