What were the occupations of the two men in the bet?

In Anton Chekhov's short story "The Bet," the two men involved in the wager are a lawyer and a banker. The lawyer bets that he can endure fifteen years of solitary confinement to prove that life imprisonment is preferable to the death penalty, while the banker, driven by pride and financial concerns, wagers a substantial sum to challenge the lawyer's claim. This bet ultimately leads to profound reflections on human nature and the value of freedom.
