Ivar Berg, Emeritus Professor of Sociology at the University of Pennsylvania, remembered for his “warmth, humor, quick wit and encyclopedic knowledge” (as quoted by OOW Section member Jerry Jacobs) passed away on January 1st.  A few of Ivar Berg’s accomplishments are highlighted in the NYT obituary, and Arne Kalleberg will be writing up a longer entry for ASA’s Footnotes later this month.  An overview of Ivar’s career can also be found here.
