Henry Carsten Kellers (July 6, 1874 – May 23, 1954)[1] was an American United States Navy Lieutenant Commander[2] who served on numerous scientific expeditions on behalf of the Smithsonian Institution. During his expeditionary career, he collected biological specimens for the Smithsonian, bringing back over 10,000 specimens, living and deceased, many which were held by the National Zoo in Washington, D.C.
Kellers participated in a number of expeditions during his Navy career, representing the Smithsonian Institution. He participated in four United States Naval Observatory Eclipse Expeditions between the years of 1925 and 1930. These expeditions included trips to Niuafo'ou, the Philippines, Sumatra and Nicaragua. On behalf of the Smithsonian he collected biological specimens, including 130 animals and birds from Nicaragua for the National Zoological Park in 1927. He also brought back, to the United States, over 10,000 specimens from the Philippines in 1929,[2] and over 120 boxes of specimens from Niuafo'ou in 1930.[4] Among the 120 boxes included four boxes of samples of a plant that grew in lava, bearing wood that sank in water.[4]
Kellers was credited for the 1930 discovery of a new genus of sea urchins endemic to Niuafo'ou, the Zenocentrotus, as well as the first two species of this genus; the Smithsonian Institution named the two species Z. kellersi (in honor of Kellers) and Z. paradoxus.[4][5] The discovery was described by the Smithsonian as "one of the most important discoveries that has been made in the well-worked field of shallow water sea-urchins in the past 100 years".[4]
