Luckner, Count Felix von (1881-1966), a German naval officer. During World War I Luckner commanded the Seeadler (“Sea Eagle”), a raiding sailing vessel disguised as a commercial ship. In less than a year—from late 1916 until his capture near the Fiji Islands—he sank 18 to 25 Allied ships, winning the nickname “Sea Devil.” He claimed no deaths resulted; he tricked his enemies and took them captive.

Luckner was born into an aristocratic family. He ran away to sea at 13. After the war he traveled widely, lecturing on his adventures.
