Irv Piliavin passed away November 19 at age 81 of cancer. Irv was an emeritus professor of social work and sociology at the University of Wisconsin. Because I knew him best as the husband of my beloved colleague Jane Piliavin, I am linking to celebrations of his career by two of his former students, Brad Wright and Chris Uggen as well as the official statement by the School of Social Work, which also gives memorial contribution information. Irv was a great guy and a creative and rigorous social scientist. He will be missed by everyone who knew him.
