A detailed 1895 lithograph by Jan Veth depicting Professor Cornelis Winkler at work with a microscope.

This lithograph by the Dutch artist Jan Veth depicts Professor Cornelis Winkler, a neurologist, engaged in scientific observation. Produced in 1895 as a supplement for the periodical 'De Kroniek', the work captures the subject in profile, hunched over a microscope. Veth, known for his meticulous approach to portraiture, employs a precise technique that emphasises the concentration of the scientist. The composition is contained within a rectangular frame, with the artist's signature initials and the date 'V '94' appearing in the upper left corner, while the subject's age, 'ÆT. 39', is noted on the right.

The rendering of the subject is marked by a controlled use of shading and line. Veth avoids unnecessary ornamentation, focusing instead on the physical posture and the mechanical details of the laboratory equipment. The lighting is subtle, casting soft shadows across Winkler's face and hands, which creates a sense of quiet intensity. This print reflects the late nineteenth-century interest in documenting intellectual and professional figures, often presenting them in their specific environments to convey their vocation.

Jan Veth was a central figure in the Dutch art world, active as both a painter and a critic. His work often displays a disciplined realism, influenced by his interest in the Old Masters and his involvement with the Tachtigers movement. This specific lithograph demonstrates his ability to translate the nuances of a sitter's character into a graphic medium. The print serves as a record of the scientific culture of the period, documenting the tools and the focus of a medical academic at the end of the century. The inclusion of the publication details at the top of the sheet provides context regarding its original distribution as an art supplement for a wider audience.
