Ulrich Friedrich-Wilhelm Joachim von Ribbentrop (German: [joˈʔaxɪm fɔn ˈʁɪbəntʁɔp]; 30 April 1893 – 16 October 1946) was a German politician and diplomat who served as Minister of Foreign Affairs of Nazi Germany from 1938 to 1945. Ribbentrop first came to Adolf Hitler's notice as a well-travelled businessman with more knowledge of the outside world than most senior Nazis and as a perceived authority on foreign affairs. He offered his house Schloss Fuschl for the secret meetings in January 1933 that resulted in Hitler's appointment as Chancellor of Germany.
