In the 1920s, transatlantic encounters between the USA and Europe redefined what it truly meant to be modern. These encounters encompassed numerous sociopolitical and cultural phenomena such as "Americanism," Hollywood, jazz, Fordism, Taylorism, and the machine age, all intricately interwoven in a complex network of mutual influences. *Modern Times* shows that the European "-isms" - Futurism, Purism, Dada, Poetism, and Constructivism - were also closely interlinked with these phenomena, which shaped the decade of the "Roaring Twenties."In the 1920s, transatlantic encounters between the USA and Europe redefined what it truly meant to be modern.
