9. Arthur Zimmermann (1864-1940)
Zimmermann is best recognized as the writer of the infamous ‘Zimmermann Telegram’ that was delivered to the German Embassy in Mexico on 19 January 1917.
The concealed telegram to Heinrich von Eckhardt in Mexico presented an offer of German support for a Mexican invasion of the U.S. The idea was that the telegram would help shift the U.S attention away from Europe and onto a battle with Mexico.
The telegram got published and struck many Americans with disbelief, however, Zimmermann later confirmed the authenticity of the telegram. Not long after, the U.S and Germany would engage in war against each other.
