Lois Jean Wille (/wɪliː/; née Kroeber; September 19, 1931 – July 23, 2019) was a Chicago-based journalist, editor, and author. She won her first of two Pulitzer Prizes in 1963 for a series on local government's failure to provide contraceptive information and services to low-income women. Her stories led to a number of important policy changes in women's healthcare, public housing, and the juvenile court systems. In 1989, she received her second Pulitzer Prize for editorial writing.
