At the Boston meeting, October 23rd, 1970, Adolf Griinbaum, President of the Philosophy of Science Association, introduced the Carnap Memorial meeting. We are assembled here to pay tribute to Rudolf Carnap because his work made an immense contribution to 20th century philosophy of science. But we also honor his memory because his life as a human being enriched the lives of those who had personal contact with him professionally or otherwise. A few of these colleagues, friends or former students of his will address you now. Herbert Feigl, Richard Jeffrey, Willard Quine and Abner Shimony will do so in person themselves. Carl Hempel is still recovering from eye surgery and has asked me to read his tribute to you on his behalf.
