It’s hard to separate the two talented humorous authors who, as co-writers, penned the best-selling novels “Twelve Chairs” and “The Golden Calf,” like Siamese twins. Ilf and Petrov, who worked together for a decade, even wrote separately in such a way that fans of their work couldn’t tell which chapters belonged to which of them—chapters of the novella “Twelve Chairs,” “The Golden Calf,” “One-Storey America,” “Unusual Stories from the Life of the Town of Kolokolamsk,” and others.
