Ivan Natanovich Kupitman

He was wearing a white shirt, it was unbuttoned, and his trousers were also stained with soot in some places from when they were putting out the fire.

Ivan Natanovich Kupitman is a dermatovenereologist, candidate of medical sciences, and head of the hospital's dermatovenereology department.

The series takes place in the 19th century. Dr. Bykov, venereologist Kupitman, and nurse Lyubov Mikhailovna work peacefully in the district hospital. Life in the village is dull, as everything proceeds at a measured pace and nothing new happens to brighten up the gray everyday life. But suddenly, three interns arrive from St. Petersburg, and their peaceful life is shattered.

He wears a white shirt with a black tie with silver lines on it. He wears a brown-beige vest with black polka dots over the white shirt. He wears a knee-length cloak over the vest. His cloak is always unbuttoned and is gray-brown in color. His trousers are tight around his thighs and hang a little loose at the bottom, beige-gray in color.

Every birthday he receives stupid gifts from Bykov.
He doesn't have the best relationship with his father, Nathan Donatovich, because he stole his woman.
His mother doesn't know that he's been married and divorced three times. She also thinks Ivan is the only member of their family who doesn't drink.
Kupitman refused to share the apartment with his ex-wife, Naina, who, after divorcing her new husband, tried to sue for the right to live in it.
He is very clean: his apartment looks great, which the interns didn’t even suspect.
Sometimes he replaces the gynecologist, Vladlen Nikolaevich, but the nurse Galya actively incites her female patients against him.
Before Kisegach wanted to invite Bykov to Venice with her, Kupitman always went instead of him.
Three years older than Bykov.
He doesn’t know that he has brothers in Odessa, Kyiv and Minsk.
Atheist.
I really wanted to take part in the birth at Kisegach.
He presented Lyuba with a plot at the Bogorodskoye Cemetery; he himself had received a similar gift at the age of 35, not far from Lyuba’s plot.
He shot Levin out of jealousy towards Lyuba.
Kupitman's character received his surname thanks to the series' producer, Vyacheslav Dusmukhametov, in honor of a university friend named Grigory Kupitman.
Besides Sophia, there are two more nieces.
In one of the New Year's episodes, he created his own brand of cognac, "Kupinyak," which turned out to be disgusting. To preserve his reputation, he poured his expensive collection into a barrel, but he couldn't sell it all, earning only 500 rubles.
