A landmark of Russian scientific pedagogy: the first edition of Ivan Alekseevich Sikorsky's foundational study of infant psychological development, issued in 1884 by the St. Petersburg publisher A. E. Riabchenko. Sikorsky (1842-1919), docent of psychiatry at the Military-Medical Academy in St. Petersburg and later professor at Kiev University, was among the earliest researchers anywhere to undertake a sustained, quantitative study of a child's development from birth, tracking weight, motor behavior, facial expression, and emotional response through the first year of life against dated observation logs reproduced in the text. Conceived partly in dialogue with the German child psychologist Wilhelm Preyer, Sikorsky's study became one of the founding texts of Russian developmental psychology and the pedagogy of early childhood, still cited as the point of origin for systematic research on the pre-school period in Russian scholarship. The work was translated abroad within the year of its publication, an unusually rapid international reception for a Russian scientific monograph of this period. Sikorsky went on to become a prominent, and in later years controversial, figure in Russian psychiatry, and is remembered outside his own field as the father of aviation pioneer Igor Sikorsky. This copy has been rebound in contemporary half-leather, with the trade stamp of a bindery in Batum on the Black Sea coast marking an early stage in the book's provenance in the Caucasus, and carries an unattributed owner's ink inscription on two preliminary leaves. Copies of the first edition are seldom offered outside institutional holdings, with most known examples surviving in Russian academic and university libraries: a foundational nineteenth-century monograph of interest equally to historians of psychology and pedagogy and to collectors drawn to the Sikorsky name through the history of aviation.
