Question: Who invented the type of script used in autographs?

full_context: Document 1: Architectural reprography: Architectural reprography, the reprography of architectural drawings, covers a variety of technologies, media, and supports typically used to make multiple copies of original technical drawings and related records created by architects, landscape architects, engineers, surveyors, mapmakers and other professionals in building and engineering trades.
Document 2: Cascajal Block: The Cascajal Block is a tablet-sized writing slab in Mexico, made of serpentinite, which has been dated to the early first millennium BCE, incised with hitherto unknown characters that may represent the earliest writing system in the New World. Archaeologist Stephen D. Houston of Brown University said that this discovery helps to "link the Olmec civilization to literacy, document an unsuspected writing system, and reveal a new complexity to [the Olmec] civilization."
Document 3: Autograph (Assyriology): An autograph in Assyriology is the hand-copy of a cuneiform clay-tablet. Producing an autograph is often the first step of a tablet's archaeological interpretation and the autograph is frequently the authoritative form that is published as source material. Autographing the text is followed by transliteration, transcription and translation.
Document 4: Sumerian King List: The Sumerian King List is an ancient stone tablet originally recorded in the Sumerian language, listing kings of Sumer (ancient southern Iraq) from Sumerian and neighboring dynasties, their supposed reign lengths, and the locations of the kingship. Kingship was seen as handed down by the gods, and could be transferred from one city to another, reflecting perceived hegemony in the region. Throughout its Bronze Age existence, the document evolved into a political tool. Its final and single attested version, dating to the Middle Bronze Age, aimed to legitimize Isin's claims to hegemony when Isin was vying for dominance with Larsa and other neighboring city-states in southern Mesopotamia.
Document 5: Anatolian hieroglyphs: Anatolian hieroglyphs are an indigenous logographic script native to central Anatolia, consisting of some 500 signs. They were once commonly known as Hittite hieroglyphs, but the language they encode proved to be Luwian, not Hittite, and the term Luwian hieroglyphs is used in English publications. They are typologically similar to Egyptian hieroglyphs, but do not derive graphically from that script, and they are not known to have played the sacred role of hieroglyphs in Egypt. There is no demonstrable connection to Hittite cuneiform.
Document 6: Hurrian foundation pegs: The Hurrian foundation pegs, also known as the Urkish lions, are twin copper foundation pegs each in the shape of a lion that probably came from the ancient city of Urkesh (modern Tell Mozan) in Syria. The pegs were placed at the foundation of the temple of Nergal in the city of Urkesh as mentioned in the cuneiform inscriptions on them. The inscription on the two pegs and the associated stone tablet is the oldest known text in the Hurrian language. One of the lions is now housed, along with its limestone tablet, in the Musée du Louvre in Paris. The second lion is on display at the Metropolitan Museum of Art in New York.
Document 7: Art of Mesopotamia: The art of Mesopotamia has survived in the archaeological record from early hunter-gatherer societies (10th millennium BC) on to the Bronze Age cultures of the Sumerian, Akkadian, Babylonian and Assyrian empires. These empires were later replaced in the Iron Age by the Neo-Assyrian and Neo-Babylonian empires. Widely considered to be the cradle of civilization, Mesopotamia brought significant cultural developments, including the oldest examples of writing.
Document 8: Early Indian epigraphy: The earliest traces of epigraphy in the Indian Subcontinent are found in the undeciphered inscriptions of the Indus Valley Civilization (Indus script), which date back to the early 3rd millennium BC. Two other important archeological classes of symbols are found from the 1st millennium BCE, Megalithic Graffiti Symbols and symbols on punch-marked coins, though most scholars do not consider these to constitute fully linguistic scripts, and their semiotic functions are not well understood. The earliest deciphered epigraphic inscriptions of significant length are the Edicts of Ashoka of the 3rd century BCE, written in forms of Prakrit in the Brahmi script. Jain inscriptions in South India written in Tamil-Brahmi, Bhattiprolu alphabet and the Kadamba alphabet are also of relatively early date. Short Brahmi inscriptions on potsherds from the 4th century BCE have been reported from the ruins of Anuradhapura and are the only pre-Ashokan examples of Brahmi that have received any scholarly acceptance, though reports have appeared in the Indian press claiming potsherd inscriptions from an even earlier period (6th to 4th century BCE).
Document 9: Amarna letter EA 9: Amarna letter EA 9, is a tall, compact 38 line (capable of 55 lines) clay tablet letter of 3 paragraphs, in pristine condition, with few flaws on the clay. The photo of the reverse (pictured) shows half of Paragraph III, and some of the signs (out of focus).
Document 10: Maya script: Mayan script, also known as Mayan glyphs or Mayan hieroglyphs, was the writing system of the Maya civilization of Mesoamerica and is the only Mesoamerican writing system that has been substantially deciphered. The earliest inscriptions found which are identifiably Maya date to the 3rd century BCE in San Bartolo, Guatemala. Maya writing was in continuous use throughout Mesoamerica until the Spanish conquest of the Maya in the 16th and 17th centuries.
Document 11: Illustrated Hieroglyphics Handbook: The Illustrated Hieroglyphics Handbook is part of a new genre of books focused on Egyptian hieroglyphs. The book is a graphics based book with four to seven word examples of each Egyptian hieroglyph; the words are graphically explained for each component of the word, and links to the other entries in the book; each hieroglyph is in "extreme-artistic-detail" and can vary for each hieroglyph, word-to-word. The determinatives ending a word are explained, (if there is one). Some determinatives are specific to individual trades, i.e. metallurgy, for example and are not in the Gardiner's sign list of Egyptian hieroglyphs.
Document 12: Jan Gunneweg: Jan Gunneweg, is a member of the Archaeometry Task-force Unit at the Institute of Archaeology of the Humanities Faculty of the Hebrew University, Jerusalem. He began research at the University in 1973 completing his Ph.D. in the Archaeometry Unit of the institution in 1981. He became a Lecturer in 1983, and Senior Lecturer in 1988. His major research interest is in discovering the place of manufacture of pottery and parchment through the use of neutron activation analysis and synchrotron radiation. He has been particularly interested in finding the place of origin of the Dead Sea Scrolls and the jars that contained them in Gunneweg and Balla 2003,2006,2010 & 2012 in. Other interests include research into the ancient preparation of parchment and ink as used in the Dead Sea scrolls. Gunneweg organized three workshops, two at the Hebrew University Science Campus in 2005 and 2010, whereas the third one in 2008 at the Lorentz Centre for Physics and Mathematics at Leiden University (Netherlands) as a NIAS and Lorentz fellow for the year 2007-2008. During two Sabbaticals in 1989 and 1996 at Lawrence Berkeley National Laboratory In Berkeley, California, he worked on the digitizing of neutron activation data obtained at LBL in the 1960s and 70s. More research was focused on the place of origin of Iron Age pottery associated with the first Iron Age settlements in the Israel highlands, the Philistines and the Mycenaean IIIA Chariot Krater and other Mycenaean pottery, found at Akko and Tel Dan. Also the origin of Nabatean and Eastern Terra Sigillata pottery have been studied and published At present, Gunneweg is particularly interested in promoting the protection of Cultural Heritage in which he lectured at the ESRF in Grenoble, SESAME at Allan, ELETTRA, Trieste, Daresbury and the CLS at Saskatoon in order to lay the foundations of a collaboration between Science and Humanities and Social Sciences, which he has dubbed Trans-disciplinary an approach that transcendents the borders/limits of any discipline.
Document 13: Neolithic signs in China: Since the second half of the 20th century, inscriptions have been found on pottery in a variety of locations in China, such as Banpo near Xi'an, as well as on bone and bone marrows at Hualouzi, Chang'an County near Xi'an. These simple, often geometric, marks have been frequently compared to some of the earliest known Chinese characters appearing on the oracle bones, and some have taken them to mean that the history of Chinese writing extends back over six millennia. However, only isolated instances of these symbols have been found, and they show no indication of representing speech or of the non-pictorial processes that a writing system requires.
Document 14: The Hieroglyphs of Ancient Egypt: The Hieroglyphs of Ancient Egypt is part of a new genre of books focussed on Egyptian hieroglyphs. The book is a primer on hieroglyphs from the viewpoint of topical use within history, with example photographs or illustrations. The later chapters discuss the hieroglyphs and the history of their translation.
Document 15: Cuneiform script: Cuneiform script ( or or ), one of the earliest systems of writing, was invented by the Sumerians. It is distinguished by its wedge-shaped marks on clay tablets, made by means of a blunt reed for a stylus. The name "cuneiform" itself simply means "wedge shaped".
