G. M. Fikhtengol'ts and the teaching of the mathematical analysis in the Russia during the first half of the XXth century

We discuss the evolution of the course of the mathematical analysis in the Russian universities during the first half of the XXth century and the role in this process of the professor of the Leningrad University G. M. Fikhtengol'ts (1888–1959), who was the author of the classical works — of the three-volume treatise «Differential and Integral Calculus» (1947–1949) and of the two-volumes text-book «The Fundamentals of Mathematical Analysis» (1955–1956).
