German naval officer
Otto Kretschmer (1 May 1912 – 5 August 1998) was a German naval officer and submariner in World War II and the Cold War. From September 1939 until his capture in March 1941 he sank 44 ships, including one warship, a total of 274,333 tons. For this he received the Knight's Cross of the Iron Cross with Oak Leaves and Swords, among other awards. He earned the nickname "Silent Otto", both for his successful use of the "silent running" capability of U boats and for his reluctance to transmit radio messages during patrols. After the war he served in the German Federal Navy, from which he retired in 1970 with the flag rank of commodore.

Kretschmer was born in Heidau near Neisse, then in the German Empire on 1 May 1912 to Friedrich Wilhelm Otto and Alice (née Herbig) Kretschmer. His father was a teacher at the local Volkschule (primary school), which Otto attended from 1918 to 1921. He then moved to a Realgymnasium (secondary school). In the aftermath of World War I the Kretschmer family remained aloof from the political turbulence of the Weimar era. Kretschmer indulged in sporting pastimes and scientific interests. Kretschmer achieved good results in mathematics and chemistry and passed his Abitur (school leaving certificate) at 17. The report contained the remark, "Kretschmer demonstrated his extraordinary courage in many instances. He wants to be a naval officer." Kretschmer was too young to enlist at 17 and his father sent him to England to broaden his horizons. He enrolled at Exeter University (then University College of the South West of England) and studied under Professor Jacob Wilhelm Schopp (b. 1871), a German–born naturalised Briton. He mastered the English language and came to respect British education: its practical focus complemented his scientific and theoretical–based German background. His time in England shaped his view of them during the war; he was quick to believe in rumours of new British inventions during the war at sea. He returned home upon his mother's death from tetanus in a medical malpractice incident. He did not return to England from his hiatus, but travelled through France, Switzerland and Italy.
