Gustav Ludwig Heinrich Mützel (December 7, 1839 – October 29, 1893) was a German artist, famous for his mammal and bird paintings, including the illustrations for the second edition of Alfred Edmund Brehm's Thierleben and Richard Lydekker's The Royal Natural History.
Subsequently, Mützel began to study at the Academy of Art at age 18 and was, amongst others, a pupil of the painter Eduard Daege.
On 1 November 1865 Mützel married Anna Schönherr in Berlin and raised three children; Hans, Walter and Gertrud.
He created a large number of illustrations for the German Ornithological Society, having been a member since 1874.
Mützel's diverse interests led also to his membership of the German Society for Anthropology, Ethnology and Prehistory and the Association of Berlin artists.
