> Henrik Grönvold (1858–1940)
Grönvold’s plates are meticulous and quietly dramatic, with delicate texturing that makes feathers feel tangible—ideal for reconstructing species from sparse records. His initials (often “H.K.”) appear on several plates in *Extinct Birds*.
He moved fluidly between scientific and popular works, illustrating everything from pheasants to African passerines. For the Hitchhikers Project, Grönvold’s oeuvre opens avenues into chromolithography workflows and the studio conventions behind “natural” poses.
His contributions to Rothschild’s book include several Mascarene parrots reconstructed from early travellers’ accounts, a notable case of image‑based inference from fragmentary sources.
