Portrait photographique de Louis Pasteur

Original albumen print photograph depicting Louis Pasteur, in cabinet card format, mounted on thick card with Chalot's imprint, photographer, 18 rue de Vivienne, Paris.

A photograph mounted on thick card, with the photographer's address printed in red in the lower margin.

A fine copy.

This portrait of Pasteur is less common than the celebrated portrait by Nadar, which is widely reproduced; the scientist appears somewhat younger here, though dressed in a similar manner, his gaze distant and unfocused. A carte-de-visite format example is held at the Musée Carnavalet in Paris. This larger format is, of course, considerably rarer.
