Metcalf gathered a collection of European and American artworks in his
Italianate-style 1854 mansion on Cass St, Milwaukee. The majority of his art was acquired during business trips to Europe in the 1870s and 1880s, and Metcalf displayed it in a purpose-built gallery extension to his house. Among major works in the collection were
William-Adolphe Bouguereau's The Lost Pleiad (1884), purchased from the artist's studio in Paris, and an 1870 portrait of artist
James McNeill Whistler by
Walter Greaves. Also included were
genre scenes by
Carl Frithjof Smith,
Nikolaos Gyzis, and
Charles Courtney Curran, as well as landscapes by
David Johnson,
Arthur B. Davies,
Constant Troyon,
Paul Weber, and
Peter Moran. Beginning in the mid-1870s, Metcalf supported various initiatives for art education in Milwaukee, such as the acquisition of a series of photographs of European painting and sculpture by
Adolphe Braun, which artist
John S. Conway had advised should be displayed in bookstores in the city. In 1882, Metcalf was appointed to the board of the art section of the newly-inaugurated Milwaukee Industrial Exposition Building, in charge of rotating exhibitions. Though he considered creating a proper art museum in town on his own funds, the proposal laid out by fellow businessman Frederick Layton to build such a structure in 1883 altered his plans. He became one of the early supporters of Layton's project and contributed donations throughout the construction phase. In addition, Metcalf and his business partner Bradley gifted a
monument to Solomon Juneau, sculpted by
Richard Henry Park, to the city of Milwaukee in 1887. == Death ==
