Abstract

Alexander Yakovlevich Pehrna (1878 - 1916) was born into a family of Estonian intellectuals. A. Ya. Pehrna received his secondary education at the 7th Petrograd Gymnasium. After graduating from high school, he entered Petrograd University in the natural department of the Faculty of Physics and Mathematics, from which he graduated in 1902 with a 1st degree diploma. Then he entered the Mining Institute, which he graduated first in 1910. While still a student, he took part in detailed geological research on the eastern slope of the southern Urals. These works provided him with material for several geological and paleontological articles on the Upper Devonian and Lower Carboniferous deposits of the Urals (see list of works in the article).
