Eponymy: Henry Sears (1913–1982) was an American naval commander during WWII. [...] Einar Koefoed (1875–1963) was a Danish-born marine biologist, though much of his work was done in Norway. He took part in the ‘Michael Sars’ (q.v.) expedition of 1910, and was a pioneer researcher on Atlantic species such as the Pollack (1932). (Ref. 128868), visit book page.
