Teddy Suhren, Ace of Aces, Memoirs of a U-Boat Rebel 

Reinhard ‘Teddy’ Suhren fired more successful torpedo shots than any other man during the war, many before he even became a U-boat commander. He was also the U-boat service’s most irreverent and rebellious commander; his lack of a military bearing was a constant source of friction with higher authority. Valued for his good humour and ability to lead, his nickname was acquired because he marched like a teddy-bear.
