He eventually served as assistant Secretary of the Smithsonian from 1850 to 1878, and as Secretary from 1878 until 1887. He was dedicated to expanding the natural history collections of the Smithsonian which he increased from 6,000 specimens in 1850 to over 2 million by the time of his death. He also served as the U.S. Commissioner of Fish and Fisheries from 1871 to 1887 and published over 1,000 works during his lifetime.
Johann Jakob Heckel was an Austrian taxidermist, zoologist, and ichthyologist from Mannheim in the Electoral Palatinate. He worked at the Royal natural history cabinet in Vienna which later became the Austrian Museum of Natural History.

The International Game Fish Association (IGFA) is the leading authority on angling pursuits and the keeper of the most current world record fishing catches by fish categories. Fishermen who are sport fishers are careful to follow their stringent rules for fair play and line requirements in order to receive the honor of being listed in their annual "World Record Game Fishes" publication. The publication also gives fishing tips, and has an extensive fish identification guide. The IGFA is also an ardent proponent of aquatic habitat conservation, and cooperates with biologists all over the world.
Theodore Dru Alison Cockerell (1866–1948) was an entomologist and systematic biologist who published nearly 4,000 papers, some of them only a few lines long. Cockerell's speciality was the insect order Hymenoptera, an area of study where he described specimens from the United States, the West Indies, Honduras, the Philippines, Africa, and Asia. Cockerell named at least 5,500 species and varieties of bees and almost 150 genera and subgenera, representing over a quarter of all species of bees known during his lifetime. In addition to his extensive studies of bees, he published papers on scale insects, slugs, moths, fish scales, fungi, roses and other flowers, mollusks, and a wide variety of other plants and animals.
George Sprague Myers was an American ichthyologist who spent most of his career at Stanford University. He served as the editor of Stanford Ichthyological Bulletin as well as president of the American Society of Ichthyologists and Herpetologists. Myers was also head of the Division of Fishes at the United States National Museum, and held a position as an ichthyologist for the United States Fish and Wildlife Service. He was also an advisor in fisheries and ichthyology to the Brazilian Government.
Storrs Lovejoy Olson was an American biologist and ornithologist who spent his career at the Smithsonian Institution, retiring in 2008. One of the world's foremost avian paleontologists, he was best known for his studies of fossil and subfossil birds on islands such as Ascension, St. Helena and Hawaii. His early higher education took place at Florida State University in 1966, where he obtained a B.A. in biology, and the University of Florida, where he received an M.S. in biology. Olson's doctoral studies took place at Johns Hopkins University, in what was then the School of Hygiene and Public Health. He was married to fellow paleornithologist Helen F. James.
Frederick Merkle Bayer was an emeritus curator of the Smithsonian Institution's National Museum of Natural History, as well as a prominent marine biologist who specialized in the study of soft corals.
Sven Oscar Kullander is a Swedish biologist specialised in ichthyology. He primarily researches cichlids – notably the genus Apistogramma and the Cichlasoma-complex – and other tropical fresh water fishes. He also has been working with endangered fish species in Sweden.
James Arthur Peters was an American herpetologist and zoogeographer.
Helen Frances James is an American paleontologist and paleornithologist who has published extensively on the fossil birds of the Hawaiian Islands. She is the curator in charge of birds in the Department of Vertebrate Zoology at the National Museum of Natural History in Washington, D.C.
The Captain Marshall Field Expeditions were undertaken by the Field Museum of Natural History in Chicago, Illinois. The two Captain Marshall Field paleontological expeditions had the goal of finding South American Cenozoic mammals. The mammals of South America had evolved in near total isolation from the rest of the world from almost the beginning of the Cenozoic Era until only a few million years ago.
John Warren Aldrich was an American ornithologist.
Richard Charles Banks was an American author, ornithologist and Emeritus Research Zoologist on staff with the Patuxent Wildlife Research Center run by the U.S. Geological Survey and stationed at the Smithsonian Institution in Washington, D.C. He is the founder of the Ornithological Council and known for his study of the migratory systems, patterns, and geographic variations of North American birds, primarily focusing on the research and analysis of Greater White-fronted Geese.
Don Ellis Wilson is an American zoologist. His main research field is mammalogy, especially the group of bats which he studied in 65 countries around the world.
Roger Lansing Grande, more commonly known as Lance Grande, is an evolutionary biologist and curatorial scientist. His research and work is focused on Paleontology, Ichthyology, Systematics and Evolution. He is well known for his work on the paleontology of the Green River Formation and for his detailed monographs on the comparative anatomy and evolution of ray-finned fishes. He has also published books on broader issues, engaging larger audiences on the importance of the natural and the social sciences.
Jun Wen is an evolutionary biologist and curator at the Smithsonian's National Museum of Natural History in the Department of Botany and has worked in the Laboratory of Molecular Systematics. She researches the monography, phylogenetics, biogeography, and ethnobotany of the plant families Araliaceae and Vitaceae. She has published over 190 scientific papers.
