ヴァルター・ウルブリヒト
In 1949 the Soviets turned control of East Germany over to the SED, headed by Wilhelm Pieck (1876–1960), who became President of the GDR and held the office until his death, while the SED general secretary Walter Ulbricht assumed most executive authority. Socialist leader Otto Grotewohl (1894–1964) became prime minister until his death.
