 These figures included Richard Huelsenbeck, Emmy Hennings, Klabund, Johannes R. Becher, Franz Jung and most importantly of all his particular friend Hugo Ball.It was Ball who interested Leybold in the expressionist movement and soon the two of them were soon producing poetry together under the pseudonym "Ha Hu Baley".In the company of these authors, Leybold experimented wildly with technique and imagery in his poetry, seeking both to develop his skills and in the process deconstruct poetry itself, heavily influenced by Alfred Kerr and Friedrich Nietzsche.
