Fifteen letters sent by the philosopher, Sir Isaiah Berlin, to Ephraim Broido. Oxford, Genoa, Zurich, and Rehovot, 1950s-1980s (mostly 1960s-1970s). English (one letter in Hebrew). Three letters handwritten; the remainder, mostly on official stationery, typewritten (some with handwritten corrections and/or addenda). All but one signed by Isaiah Berlin. Most of the letters deal with the subject of rescuing "Molad, " the journal founded and edited by Ephraim Broido, from threats of closure. They contain Berlin's instructions and words of advice and encouragement to Broido, written over a period of many years. Among other things, Berlin suggests that Broido approach potential financial sponsors in a particular style or with a particular type of argument; he recommends approaching specific people of influence (such as Hebrew University President Eliahu Eilat, Chairman of the Jewish Agency Pinchas Sapir, the diplomat Yaakov Herzog, and the philanthropist Sir Isaac Wolfson); and he provides Broido with updates regarding the status of various requests. In a letter from 1969 (whose contents Berlin requests remain confidential), Berlin informs Broido of an upcoming grant of 12,000$ obtained for Molad's benefit. Additional subjects addressed in the letters concern translations of Berlin's writings appearing in Molad, and the delivery of books, money, and other things.
