Louis Pasteur's three artist compatriots-Henner, Pointelin, and Perraud: A story of friendship, science, and art in the 1870s and 1880s.

Biographers have largely ignored Louis Pasteur's many and varied connections with art and artists. This article is the second in a series of the authors' studies of Pasteur's friendships with artists. This research project has uncovered data that enlarge the great medical chemist's biography, throwing new light on a variety of topics including his work habits, his social life, his artistic sensibilities, his efforts to lobby on behalf of his artist friends, his relationships to their patrons and to his own patrons, and his use of works of art to foster his reputation as a leader in French medical science. In a prior article, the authors examined his unique working relationship with the Finnish painter Albert Edelfelt and the creation of the famous portrait of Pasteur in his laboratory in the mid-1880s. The present study documents his especially warm friendship with three French artists who came from Pasteur's home region, the Jura, or from neighboring Alsace. A forthcoming study gives an account of his friendships with Max Claudet and Paul Dubois, both of whom made important images of Pasteur, and it offers further illustrations of his devotion to the fine arts.
