Koehler included two prints by Swiss artist Maria Anna Angelica Kauffman in the exhibition’s section on aquatint, a type of etching process. The differences between these works (see also Woman Braiding Her Hair) highlight the great variety of effects printmakers can achieve with aquatint. Throughout his career, Koehler advocated for women artists and printmakers; in 1887, the year he was appointed curator at the MFA, he organized a groundbreaking exhibition of American women etchers.
