DAVID BOTSTEIN, who served as director of the Lewis-Sigler Institute for Integrative Genomics for 10 years, will become the chief scientific officer for Calico, a Google company that will focus on aging and illness. Arthur D. Levinson *77 is Calico’s chief executive officer.
KWAME ANTHONY APPIAH, a member of the philosophy department since 2002 who is perhaps best known for his writings on global ethics and cosmopolitanism, is moving this month to New York University. He plans to teach both on the main campus and abroad.
IN MEMORIAM PETER B. LEWIS ’55, the chairman of Progressive Corp. whose gifts to the University totaled more than $220 million, died of a heart attack Nov. 23 in Coconut Grove, Fla. He was 80. Lewis, who turned his father’s firm into one of the nation’s largest auto-insurance companies, supported progressive and often-controversial causes, including the legalization of marijuana. His legacy at Princeton includes the Lewis Library, Lewis-Sigler Institute for Integrative Genomics, and Lewis Center for the Arts. At the center’s public launch in 2007, President Shirley Tilghman described Lewis as Princeton’s “modern-day version of Lorenzo de’ Medici.”
