Question: What prize did the author win, in 1979, who first used the term recursive acronym in print ?
Context: The ZINC database (recursive acronym: "ZINC is not commercial") is a curated collection of commercially available chemical compounds prepared especially for virtual screening.  ZINC is used by investigators (generally people with training as biologists or chemists) in pharmaceutical companies, Douglas Richard Hofstadter (born February 15, 1945) is an American professor of cognitive science whose research focuses on the sense of "I" (sense of self in relation to the external world), consciousness, analogy-making, artistic creation, literary translation, and discovery in mathematics and physics.  Hofstadter's book "Gödel, Escher, Bach: An Eternal Golden Braid", first published in 1979, won both the Pulitzer Prize for general non-fiction PGF/Ti"k"Z is a tandem of languages for producing vector graphics from a geometric/algebraic description.  PGF is a lower-level language, while Ti"k"Z is a set of higher-level macros that use PGF.  The top-level PGF and Ti"k"Z commands are invoked as TeX macros, but in contrast with PSTricks, the PGF/Ti"k"Z graphics themselves are described in a language that resembles MetaPost.  Till Tantau is the designer of these languages, and he is also the main developer of the only known interpreter for PGF and Ti"k"Z, which is written in TeX.  PGF is an acronym for "Portable Graphics Format".  Ti"k"Z was introduced in version 0.95 of PGF, and it is a recursive acronym for "Ti"k"Z ist "kein" Zeichenprogramm" (German for "Ti"k"Z is "not" a drawing program"). GiNaC is a free computer algebra system released under the GNU General Public License.  The name is a recursive acronym for "GiNaC is Not a CAS" (Computer Algebra System).  This is similar to the GNU acronym "GNU is not Unix". A recursive acronym is an acronym that refers to itself.  The term was first used in print in 1979 in Douglas Hofstadter's book "Gödel, Escher, Bach: An Eternal Golden Braid", in which Hofstadter invents the acronym GOD, meaning "GOD Over Djinn", to help explain infinite series, and describes it as a recursive acronym.  Other references followed, however the concept was used as early as 1968 in John Brunner's science fiction novel "Stand On Zanzibar".  In the story, the acronym EPT (Education for Particular Task) later morphed into "Eptification for Particular Task". PHP is a server-side scripting language designed primarily for web development but also used as a general-purpose programming language.  Originally created by Rasmus Lerdorf in 1994, the PHP reference implementation is now produced by The PHP Development Team.  PHP originally stood for "Personal Home Page", but it now stands for the recursive acronym "PHP: Hypertext Preprocessor". Die Partei für Arbeit, Rechtstaat, Tierschutz, Elitenförderung und basisdemokratische Initiative ("Party for Labour, Rule of Law, Animal Protection, Promotion of Elites and Grassroots Democratic Initiative"), using the recursive acronym Die PARTEI ("The PARTY"), is a German political party that was founded in 2004 by the editors of the German satirical magazine "Titanic".  It is led by Martin Sonneborn.  In the 2014 European Parliament election, the party won a seat, marking the first time that a satirical party has won a seat to the European Parliament. P.I.P.S. is a term (recursive acronym) for Symbian software libraries that means, P.I.P.S. Is POSIX on Symbian OS.  It is intended to help C language programmers in migration of desktop and server middleware, applications to Symbian OS based mobile smartphone devices. Xinu Is Not Unix (Xinu, a recursive acronym), is an operating system for embedded systems, originally developed by Douglas Comer for educational use at Purdue University in the 1980s.  The name is both recursive, and is "Unix" spelled backwards.  It has been ported to many hardware platforms, including the DEC PDP-11 and VAX systems, Sun-2 and Sun-3 workstations, Intel x86, PowerPC G3 and MIPS.  Xinu was also used for some models of Lexmark printers. Gajim is an instant messaging client for the XMPP protocol which uses the GTK+ toolkit.  The name Gajim is a recursive acronym for "Gajim's a jabber instant messenger".  Gajim runs on Linux, BSD and Microsoft Windows.  Released under the GNU General Public License, Gajim is free software.  A 2009 round-up of similar software on Tom's Hardware found version 0.12.1 "the lightest and fastest jabber IM client".
