In 2017-2018, the Whitney Humanities Center at Yale University celebrates the final year of its Andrew W. Mellon Mid-Career Research Fellowship Program, “Thinking the Humanities in the 21st Century.” The Fellowship has been directed toward teachers at four-year liberal arts colleges who received tenure within five years of their appointments as fellows. For its final year, it has welcomed four outstanding scholars to the Whitney Humanities Center, where they are pursuing their research on topics in the humanities and related fields while they enter into intellectual exchanges with faculty, fellows, and other visitors to the Center. The Whitney and Yale are most grateful to the Andrew W. Mellon Foundation for funding this pilot program.
