This richly illustrated volume paints a complex portrait of Caillebotte, masculinity, and identity in late nineteenth-century France. More than any other French Impressionist, painter Gustave Caillebotte (1848-1894) observed and depicted the many men in his life, including his brothers and friends, employees, and the workers and bourgeois in his Parisian neighborhood. Male subjects feature prominently in some of his best-known works, such as The Floor Scrapers, Man at His Bath, Young Man at His Window, Boating Party, and Paris Street, Rainy Day. The originality of his paintings of men is fully explored for the first time in this catalogue, published to accompany a major international exhibition co-organized by the J. Paul Getty Museum, Musée d'Orsay, and the Art Institute of Chicago. Alongside paintings, drawings, and photographs, as well as an appendix featuring maps and new biographical research that sheds light on Caillebotte's social network, this volume includes historically grounded thematic essays by curators and leading scholars. By exploring the complex and varied facets of Caillebotte's identity--as son, brother, soldier, bachelor, amateur, sportsman, and so on--these essays pose questions of identity, leaving space for ambiguous and fluid expressions of gender and masculinity--for both Caillebotte and the larger late nineteenth-century French world. This volume is published to accompany an exhibition on view at the Musée d'Orsay from October 8, 2024, to January 19, 2025, J. Paul Getty Museum at the Getty Center from March 25 to May 25, 2025, and The Art Institute of Chicago from June 29 to October 5, 2025.
