Boulenger developed a lifelong passion for animals, which led him to study zoology at the university. During his university years, he gained recognition at the Musee d'Histoire Naturelle, Brussels and was hired as an assistant naturalist in 1880. Two years later, he joined the
British Museum's Department of Zoology as a first-class assistant, under the leadership of
Dr. Gunther. Boulenger held this position until his retirement in 1920. According to biographical accounts, he was incredibly methodical and had an amazing memory that enabled him to remember every specimen and scientific name he ever saw. He also had extraordinary powers of writing, seldom made a second draft of anything he wrote, and his manuscripts showed but few corrections before going to the publisher. Boulenger also played the
violin, could speak French, German, and English apart from reading Spanish, Italian and a bit of Russian. As a zoologist, he also had a working knowledge of both Greek and Latin. By 1921, Boulenger had published 875 papers totaling more than 5,000 pages, as well as 19 monographs on fishes, amphibians, and reptiles. The list of his publications and its index of species cover 77 printed pages. He described 1,096 species of fish, 556 species of amphibians, and 872 species of reptiles. He was famous for his monographs on amphibians,
lizards and other reptiles, and fishes, for example, his monographs on the fishes of
Africa. He was a member of the
American Society of Ichthyologists and Herpetologists and was elected its first honorary member in 1935. In 1937, Belgium conferred on him the
Order of Leopold, the highest honor awarded to a civilian. == Personal life ==
