Wladimir Klitschko

Dr. Wladimir Klitschko is the creator of the FACE the Challenge method, an entrepreneur, a bestselling author, and the longest-reigning heavyweight boxing world champion. Since the start of Russia’s war of aggression against Ukraine, he has stood by his compatriots and used his international influence and connections to draw attention to the injustice of the war and generate widespread support. In September 2026, the book *STARK SEIN. Vertrau auf dich!* (Be Strong: Trust Yourself!) from the “WAS IST WAS” series will be published; he co-authored it with Tatjana Kiel and Andrea Weller-Essers for Tessloff Verlag.
