Rear Admiral Karl Rudolf Brommy (changed his name to reflect the English pronunciation of his original name, Bromme) (10 September 1804 – 9 January 1860) was a German naval officer who helped establish the first unified German fleet, the Reichsflotte, during the First Schleswig War which broke out just before the Revolutions of 1848 in the German states.
During his youth, he had served in the Chilean, Brazilian, and Greek Navies under the command of Admiral Thomas Cochrane, 10th Earl of Dundonald.
A skilled sea commander, Brommy also made significant contributions to German naval education and shore infrastructure.
