Ilf and Petrov
Ostap Bender's origins are mysterious; he mentions only that his father was "a Turkish subject", his mother was "a Countess and received unearned incomes" and that his full name is Ostap-Sulayman-Berta-Maria-Bender-Bey (Остап-Сулейман-Берта-Мария-Бендер-Бей). In the comments to the "Complete Works" of Ilf and Petrov by M. Odessky and D. Feldman, this phrase is explained as a hint to his supposed Jewish origin from a port city in Novorossiya, most probably Odessa, where many Jews claimed Turkish citizenship to evade discrimination and conscription for military service. Some of them indeed held Turkish citizenship, such as Julius Martov.
