German submarine commander in the First World War, who served as lieutenant commander of the submarine U 26, a diesel-electric high-sea boat, from 1 August 1914 until its demise in the fall of 1915, only interrupted by a short command of the sister boat U 23 from 18 December 1914 to 12 January 1915.
Berckheim and his boat were deployed in the Baltic Sea where he had his greatest success on 28 September OS/ 11 October 1914 NS, when he torpedoed the Russian battleship Pallada at the entrance to the Gulf of Finland 16.5 nm from Russarö. It exploded ammunition chambers on the cruiser, which sank within a few minutes with its entire crew of 597 men. This was the first total loss of a ship of the Russian Navy in the First World War.
Berckheim on U 26 also sank three merchant ships (Frack, Pechora, Semlja) with a total of 3,700 GRT and in May 1915 the Russian Mine-laying Yenisei.
U 26 did not return from an enemy journey in August 1915. It is believed that the boat hit a Russian mine and sank off the Finnish coast. Berckheim and all 29 men of his crew were killed. The boat was discovered and identified by divers in the Gulf of Finland in May 2014, very close to where the Pallada sank and remains well preserved.
