Question: When was the founder of The Warden and the College of the Souls of All Faithful People Deceased in the University of Oxford born?

<P0-S0> The Oxford University Society of Bibliophiles is a book collecting and bibliophile club run by, and primarily for, students at Oxford University. <P0-S1>  It was founded in 1950 by a group of young bibliophiles headed by John Granger, Bent Juel-Jensen and R. John Rickett, and the first meeting was held in Hilary Term of 1951. <P0-S2>  For fifty years the Society held regular lectures, visits and other events during the University terms, and many of the leading bibliographers, librarians, book collectors, booksellers and other literary figures of the period spoke to the Society or hosted visits. <P0-S3>  Many of the Society's junior members went on to become prominent figures in the world of books, and some later served as senior members of the Society. <P0-S4>  One of the most influential members was John Sparrow, Warden of All Souls, who encouraged a love of books and manuscripts in a generation of students, and hosted a termly "Warden's Meeting" at which members were encouraged to bring items from their own libraries to pass round and say a few words about; the tradition of the "Warden's Meeting" continued after 1986, when the Warden himself was too ill to host the meetings and, indeed, after his death in 1992. <P0-S5>  Another of the Society's traditions was the quality of the termly programme cards, often produced by the leading printers and private presses of the age, including the Oxford and Cambridge University Presses, the Rampant Lions Press, the Samson Press, the Fantasy Press, the Kit-Cat Press, Big Wheel Press, the Perpetua Press, the Incline Press, the Whittington Press, the Libanus Press, the Rocket Press, the Stanbrook Abbey Press and the Stamperia Valdonega. <SEP> <P1-S0> Henry Chichele (also Checheley) ("c." 1364 – 12 April 1443), was an English archbishop and founder of All Souls College, Oxford. <SEP> <P2-S0> All Souls College (official name: The Warden and the College of the Souls of All Faithful People Deceased in the University of Oxford) is a constituent college of the University of Oxford in England. <SEP> <P3-S0> Gabriel Gorodetsky (born 13 May 1945) is a Quondam Fellow of All Souls College, Oxford, and emeritus professor of history at Tel Aviv University. <P3-S1>  Gorodetsky studied History and Russian Studies at the Hebrew University in Jerusalem and went on to obtain his Ph.D degree under the supervision of British historian E. H. Carr in Oxford. <P3-S2>  He was the director of the Cummings Center for Russian Studies at Tel Aviv University from 1991–2007. <P3-S3>  He has been a visiting fellow of St. Antony's College in Oxford in 1979 and in 1993, of the Woodrow Wilson International Center for Scholars in Washington in 1986, of All Souls in Oxford in 2006, and a visiting scholar at the Institute for Advanced Study in Princeton. <P3-S4>  Gorodetsky was also a visiting professor at the universities of Munich and Cologne, and at the Central European University in Budapest. <P3-S5>  In 2010 Gorodetsky received an honorary doctorate from the Russian State University for the Humanities in Moscow.
