> John Gerrard Keulemans (1842–1912)
Keulemans was one of the most prolific illustrators of the late Victorian era, a mainstay of Victorian natural history publishing. Working for journals and monographs across Europe, he helped set the visual language of scientific bird art - wikipedia 
For the Rothschild volume he contributed several of the most recognisable colour plates, combining rigorous draftsmanship with carefully observed posture and plumage. His work sits at the hinge between hand‐coloured lithography and photo-reproductive printing.
Keulemans often reconstructed birds from partial skins and traveller accounts—an early form of specimen‑based reconstruction that underpins how we imagine lost species today.
