It was back in 1903 that Dr. Karl Vogt arrived in Japan. Originally having aimed for a career as a conductor or composer, Vogt had changed his mind and studied Japanese and jurisprudence in order to be accepted into the Foreign Service at the Department for Foreign Affairs. After passing the Japanese-translator examination, completion of legal training, and passing the law examination followed by a doctorate in law and military service, Vogt arrived in Japan in 1903 to begin his career at the German embassy. Although Vogt’s legal comments and opinions were appreciated by his superiors at the Embassy, his prospects for promotion were bleak and he was not satisfied with the progress his diplomatic career was taking. With his doctorate in German Law, Vogt was admitted as a Japanese Patent Attorney on February 8, 1910. As he was known and appreciated in the German community for his work in the Foreign Service, Vogt proceeded to set up a patent law firm in Yokohama. Together with English barrister Charles Neville Crosse and Australian solicitor Heath, Vogt founded the joint practice “Crosse, Heath & Vogt” leading the German practice at a time when German commerce with Japan was flourishing. Requests for counsel on general legal matters could be fielded by Japanese attorneys-at-law and, if necessary, they were able to conduct proceedings before the courts.
World War I broke out in the summer of 1914, and Vogt was called in for military service in the province of Tsingtao. During this time, office work was continued by his Japanese attorney-at-law colleagues.
