Bringing together more than 80 pictures taken by American photographers from the 19th century to today, “(un)expected families” explores the definition of the American family—from the families we are born into to the ones we have chosen for ourselves. The works on view depict a wide range of relationships, including multiple generations, romantic unions, and alternative family structures. Using archival, vernacular, and fine art photographs, “(un)expected families” offers a variety of perspectives on the American family, from Dorothea Lange’s depiction of a migrant family at the time of the Dust Bowl to Louie Palu’s portraits of US Marines fighting in Afghanistan. The exhibition illustrates that the family has always taken diverse forms: affluent and destitute, cohesive and fractured, expected and unexpected. Taken together, the photographs challenge visitors to consider what family means to them. “(un)expected families” features renowned practitioners like Nan Goldin, Carrie Mae Weems, LaToya Ruby Frazier, and Harry Callahan, as well as numerous Boston-area artists, such as David Hilliard, Nicholas Nixon, Abe Morell, and Sage Sohier.
