“It wasn’t an assignment,” says Annie Leibovitz. “It was very personal. I traveled alone to places that interested me. There were no people in the pictures. I photographed houses and landscapes and objects that belonged to people who were no longer there.” People like Charles Darwin, Emily Dickinson, Virginia Woolf, and Georgia O’Keeffe. These images, combined with more recent photographs, are the subject of the online exhibition “Still Life.” Leibovitz also debuts Upstate (2020), a grid composed of nine photographs the artist took while in quarantine in upstate New York. All proceeds from the sales of Upstate, an edition of 100 prints, will go to the COVID-19 Solidarity Response Fund for the World Health Organization, as part of Hauser & Wirth’s #artforbetter initiative. —L.J.
