Konstantinov, a cosmopolitan traveler, was the first Bulgarian to write about his visits to Western Europe and America. His visits to the World Exhibitions in Paris in 1889, Prague in 1891 and Chicago in 1893 - including a visit to Niagara Falls - provided Bulgarian readers, who had recently gained independence from nearly 500 years of Turkish Ottoman oppression, with a portrait of the developed world. "To Chicago and Back" (where Bay Ganyo appears again), his travel notes from his American trip, spurred a lasting interest in Chicago, which today boasts the largest concentration of Bulgarian immigrants in the United States. There is a bust of the writer in the University of Chicago's Regenstein Library and a section of Irving Park Road in Chicago is named after him.
