オットー・ブラウン
Otto Braun (28 September 1900 – 15 August 1974) was a German Communist journalist and functionary of the Communist Party of Germany with a long and varied career. His most significant role was as a Comintern agent sent to China in 1934, to advise the Communist Party of China (CPC) on military strategy during the Chinese Civil War. At the time Braun adopted a Chinese name, Li De (); it was only many years later that Otto Braun and "Li De" came to be known as the same person.
