Lionel Walter Rothschild

Born 8 Feb 1868; died 27 Aug 1937 at age 69.British zoologist and collector (2nd Baron Rothschild (of Tring)) who founded the Walter Rothschild Zoological Museum, Tring, which opened to the public in 1892 and is now part of the Natural History Museum. His interest in natural history began when he was a child, collecting butterflies. Numerous species and sub-species of animals were named after him. From Tring, he issued Novitates Zoologicae, and published scores of scientific papers. He was the eldest son of financier Nathan Mayer Rothschild, 1st Baron Rothschild, whom he disappointed by devoting his life to natural history instead of the family banking business. He received his titles on the death of his father in 1915.«
