Ostap Vyshnia (real name Pavlo Hubenko) was a Ukrainian writer, humourist, satirist, and medical official (feldsher). Nicknamed by many critics as the Ukrainian Mark Twain and the Ukrainian Printing King.

Several satirical articles were also printed in this same newspaper by the young writer. His period of regular publication began in April 1921, when he became a journalist with the government newspaper News of the All-Ukrainian Central Executive Committee (Ukrainian: Вісті ВУЦВК). The pen name Ostap Vyshnia first appeared in The Peasant Truth on 22 July 1921, in the feuilleton Odd Fellow, Really!.
