Charles Atwood Kofoid

Charles Atwood Kofoid (11 October 1865 – 30 May 1947) was an American zoologist known for his collection and classification of many new species of marine protozoans which established marine biology on a systematic basis.

Kofoid also wrote a volume on the biological stations of Europe.

In 1920, Kofoid and US zoologist Olive Swezy (1873-1968), published Pavillardia Kof. & Swezy 1920 (a genus of dinoflagellates) in Univ. Calif. Publ. Zool. pages 323-324. It was named in honour of Jules Pavillard.

In 1921, Kofoid and Olive Swezy, wrote a book about unarmored dinoflagellates in La Jolla, California, in which they described a new genus called Torodinium (with Torodinium robustum and the type species Torodinium teredo). They also published Gyrodinium, which is a genus of dinoflagellates belonging to the order Gymnodiniales in 'Memoirs of the University of California'. vol.5.

In 1929, botanist Pavillard first described Kofoidinium, which is a genus of dinoflagellates belonging to the family Kofoidiniaceae.

Kofoid was elected to the American Academy of Arts and Sciences in 1913, the United States National Academy of Sciences in 1922, and the American Philosophical Society in 1924.
