Eveline Du Bois-Reymond Marcus, German zoologist and academic (b. 1901)
Eveline du Bois-Reymond Marcus (6 October 1901 – 31 January 1990) was an exceptionally influential German zoologist and highly skilled scientific illustrator, renowned for her profound contributions to malacology, particularly the study of marine invertebrates. Born in Berlin, Germany, her intellectual curiosity and artistic talent converged to create a distinguished scientific career.
As a zoologist, Eveline Marcus specialized extensively in molluscs, with a significant focus on the fascinating and diverse group of marine gastropods known as Opisthobranchia, commonly referred to as sea slugs. Her meticulous research involved the detailed anatomical and morphological description of numerous new species, expanding our understanding of marine biodiversity. Many of her pioneering studies were conducted alongside her esteemed husband, Ernst Marcus, himself a prominent zoologist, after their emigration from Germany to Brazil in 1936 due to the socio-political climate of the time. This move marked a pivotal period in their joint careers, establishing them as leading figures in Brazilian natural history and marine biology.
Beyond her rigorous scientific analysis, Eveline Marcus was also an accomplished scientific drawer, a role integral to her research. Her drawings were not merely artistic representations but precise, anatomical illustrations that served as indispensable scientific documentation. These highly detailed visual records were critical for identifying and classifying the new species she and Ernst discovered, providing clarity and accuracy that words alone could not convey. Her artistic precision combined with scientific exactitude made her illustrations invaluable assets in numerous publications, cementing her legacy as both a scientist and an artist.
