T. W. Wood (born Thomas Wood, summer 1839 – c. 1910) was an English zoological illustrator responsible for the accurate drawings in major nineteenth century works of natural history including Darwin's The Descent of Man and Wallace's The Malay Archipelago. He studied the courtship display behaviour of pheasants, observing them closely and publishing the first description of the double-banded argus pheasant. He illustrated many books, often of birds but also of moths and mammals. — Charles Darwin: The Descent of Man — Alfred Russel Wallace: The Malay Archipelago
