Passing of Robert A. Frosch

Our great friend and colleague Robert A. Frosch passed away 30 December 2020 at age 92. Jesse Ausubel met Bob in November 1977 at the first meeting of the NASEM Climate Research Board, and we cooperated for the next 40 years. Bob chaired the National Academy of Engineering study group that produced the 1989 book Technology and Environment with the opening essay, Technology and Environment: An Overview by Jesse H. Ausubel, Robert A. Frosch, and Robert Herman. A Remembrance will follow.
