David Rubio, (born David Joseph Spinks, Perry, New York), 1934 - died Cambridge on 21 October 2000) was an English maker of stringed musical instruments. His creations included guitars, lutes, harpsichords, theorbos, vihuelas, citterns, panduras, and finally also violins, violas and cellos. His instruments were prized during his lifetime by many fine musicians including the English lutenist and guitarist Julian Bream. The Rubio Quartet named themselves in his honour.

David Rubio acquired his new surname in his twenties while professionally playing flamenco guitar which he had learned studying in Seville with, among others, the guitarist Pepe Martinez. In the early 1960s he traveled from Spain to New York as accompanist for the Rafael de Cordoba flamenco dance company. While in New York, Rubio abandoned playing in favor of the construction of guitars and established his first workshop on Carmine Street in New York's Greenwich Village. Eventually he returned to England and set up a workshop near Oxford, later relocating his workshop to Cambridge. Over time he expanded his repertoire to include the various other instruments mentioned above. With the help of eminent Cambridge scientists, he investigated many aspects of the technology of instrument-making, such as aspects of classical violin varnish and ground layer, in his attempt to re-create the classical sound and appearance of the old Cremonese instruments.

David (Hebrew: דָּוִד, דָּוִיד, Modern David Tiberian Dāwîḏ; ISO 259-3 Dawid; Strong's Daveed; beloved; Arabic: داوود‎ or داود‎ Dāwūd) was, according to the Hebrew Bible, the second king of the United Kingdom of Israel and, according to the Gospel of Matthew and the Gospel of Luke, an ancestor of Jesus. David is seen as a major Prophet in Islamic traditions. His life is conventionally dated to c. 1040–970 BC, his reign over Judah c. 1010–1003 BC,^{[citation needed]} and his reign over the United Kingdom of Israel c. 1003–970 BC.^{[citation needed]} The Books of Samuel, 1 Kings, and 1 Chronicles are the only sources of information on David, although the Tel Dan stele records "House of David", which some take as confirmation of the existence in the mid-9th century BC of a Judean royal dynasty called the "House of David".

David is very important to Jewish, Christian and Islamic doctrine and culture. In Judaism, David, or David HaMelekh, is the King of Israel, and the Jewish people. Jewish tradition maintains that a direct descendant of David will be the Messiah. In Islam, he is known as Dawud, considered to be a prophet and the king of a nation. He is depicted as a righteous king, though not without faults, as well as an acclaimed warrior, musician, and poet, traditionally credited for composing many of the psalms contained in the Book of Psalms.
