What is the name of the character in 'Oblomov' who is Oblomov's friend and foil?

The character who is Oblomov’s friend and foil in Ivan Goncharov’s “Oblomov” is Andrei Stoltz. Stoltz’s practical energy and disciplined outlook sharply contrast with Ilya Ilyich Oblomov’s passivity, hesitation, and devotion to comfortable inactivity.

Stoltz is Oblomov’s lifelong friend from childhood. He is the son of a German father and a Russian mother, and his upbringing combines strict lessons in efficiency with the warmth of Oblomov’s more indulgent household. As an adult, Stoltz is hardworking, organized, and willing to act—qualities that make him the natural counterpoint to Oblomov’s inability to manage his estate or leave his bed.

Throughout the novel, Stoltz repeatedly tries to rescue his friend from financial trouble and emotional stagnation. He introduces Oblomov to Olga Ilyinskaya and later helps repair the damage caused by dishonest associates such as Taranteyev. Yet Stoltz cannot permanently transform Oblomov, whose dream of a quiet, protected life ultimately defeats every reforming effort.

A common mix-up is confusing Stoltz with Ilya, Oblomov’s first name, or with Zakhar, his servant. Stoltz is not merely a supporting friend: he is the novel’s principal contrast to Oblomov and embodies action, modernity, and practical responsibility.
