He died after being bitten by a boomslang snake. 

Jim Cronin was an American zookeeper best remembered for co-founding the Monkey World Ape Rescue Centre in Dorset, England, in 1987. The centre works as a sanctuary for neglected and abused primates. Jim Cronin was celebrated for his expertise in the rescue and rehabilitation process of abused primates.

PZ Myers is a biologist known for founding the Pharyngula science blog. His blog is one of the top-ranked blogs by a scientist. A "science geek" from an early age, he obtained a Ph.D. in biology from the University of Oregon. As an academician, he has taught at the University of Oregon, the University of Utah, and Temple University.  

Popularly known as The Shark Lady, American ichthyologist Eugenie Clark is remembered for her pathbreaking studies on shark behavior and poisonous fishes. A marine conservationist too, she had established the Mote Marine Laboratory. She also taught at the University of Maryland and authored 2 widely-appreciated books.

US ornithologist, environmentalist, and wildlife artist Roger Tory Peterson was one of the leading figures of the environmental movement of the 20th century. Known for his iconic books such as Wild America and the Peterson Field Guide Series, he received countless honors and awards, too, such as the US Medal of Freedom.

Edmund Beecher Wilson was an American geneticist and zoologist. He is credited with writing a textbook titled The Cell which is widely regarded as one of the most influential and important books in modern biology. Regarded as America's first cell biologist, Wilson is also credited with discovering the XY sex-determination system which is used to classify several mammals, including humans.

Copley Medal-winning US geologist and mineralogist James Dwight Dana is remembered for his path-breaking studies on topics such as mountain building, marine life, coral reefs, volcanic activity, and continents. A System of Mineralogy and Manual of Mineralogy are 2 of his iconic works, the latter of which became a standard text.

American naturalist, ornithologist, and vertebrate zoologist Spencer Fullerton Baird was an expert on North American birds and mammals. Initially a professor of natural history, he was later associated with the Smithsonian Institution as a curator and assistant secretary. He was also instrumental in the establishment of the US Commission of Fish and Fisheries.

Clinton Hart Merriam was an American mammalogist, zoologist, ornithologist, ecologist, entomologist, geographer, ethnographer, physician, and naturalist. Referred to as the father of mammalogy, Merriam owned a private collection of mammal specimens. Clinton Hart Merriam is also credited with co-founding the National Geographic Society and the American Ornithologists' Union.

Zoologist Theophilus Painter made some groundbreaking studies on chromosomes, with special focus on the X and Y chromosomes and chromosomes of the salivary glands of the Drosophila fly. The Yale alumnus was associated with the University of Texas, where he eventually became the president.

Best known for his contribution to the geosynclinal theory of mountain building, paleontologist and geologist James Hall had also taught at the Rensselaer Polytechnic Institute and worked at the Geological Survey of New York. The National Academy of Sciences member had also penned works such as The Paleontology of New York.

Alpheus Hyatt was an American paleontologist and zoologist. He is credited with co-founding a scientific journal named The American Naturalist for which he served as the editor between 1867 and 1870.
