Emil Karl Heinrich von Richthofen (11 July 1810 – 20 June 1895, at Baden-Baden), was a Prussian baron (freiherr) and diplomat.
His son Oswald von Richthofen, the future Imperial German foreign minister, was born in Jassy in 1847.
During this time he organised a visit to Hamburg by the fledgling Prussian Navy, led by Prince Adalbert of Prussia, to whom he was appointed Premier Lieutenant and Personal Adjutant.
On 24 June 1866, he visited two prominent members of Hamburg's House of Burgesses (Burgerschaft), Isaac Wolffson (former President of the Burgerschaft and member of the Right party) and Johannes Halben (leader of the Left party), to inform them of the intended rejection of the Prussian proposals by the Senate.
[7] Krüger, still their Bundestag envoy, was not without influence on the decisions during the critical hours, and then had to return to Frankfurt to make a joint statement of the three cities.
