In this interview with Judith R. Goodstein, the Italian physicist Franco Rasetti, born in 1901, talks about his experiments at Caltech on the Raman effect in the late twenties, his passion for bugs, fossils, and flowers, and doing physics in Florence, Rome, Berlin, and Quebec. Rasetti also reminisces about the Rome school of mathematics, and about other scientists he has known and worked with in Europe and North America, including Robert and Glenn Millikan, Lise Meitner, Otto Hahn, Werner Heisenberg, and Bruno Pontecorvo.
