Born in Cambridge and educated at Emmanuel College. Shortly after obtaining his degree moved to Nottingham where he was attached to the University College for seven years as Lecturer in Natural Sciences and for thirty four years as Professor of Biology. At the same time as carrying out his duties at the College, he also acted as Director of the Nottingham Natural History Museum, and during the forty five years he held this post he was responsible for building up the collections and establishing the Museum's reputation.
Carr was a keen botanist and an ardent entomologist studying the more neglected groups in particular. His greatest claim to fame as an entomologist however was not so much as a collector, but as the compiler of The Invertebrate Fauna of Nottinghamshire, the first part of which containing 618 pages was published in 1916, and the second part containing 287 pages in 1935. The work was started as early as 1893 when Carr published A Contribution to the Geology and Natural History of Nottinghamshire, a small publication, to coincide with a visit of the British Association. In compiling The Invertebrate Fauna he was much assisted by the members of the Nottingham Naturalist's Society, of which he was at one time Honorary Secretary and at another President.
Mick Cooper informs me that there is further information about Carr in Nottingham Museum and Pedersen (2002),119, records letters (1915-1925) from him to C.J.Wainwright in the RESL. FRES 1915 - death. There are obituaries in Ent, 1939, 248 (by A.R.Leivers), and in North West Naturalist, 14, 1939, 81. (MD 1/O2)
