David Randolph Scott (born June 6, 1932) is an American engineer, test pilot, retired U.S. Air Force officer, and former NASA astronaut and engineer, who was one of the third group of astronauts selected by NASA in October 1963. As an astronaut, Scott became the seventh person to walk on the Moon.

Before becoming an astronaut, Scott graduated from the West Point Military Academy and joined the United States Air Force. Scott eventually retired from the Air Force in 1975 with the rank of Colonel, and more than 5600 hours of logged flying time.

As an astronaut, Scott made his first flight into space as pilot of the Gemini 8 mission along with Neil Armstrong in March 1966, spending just under eleven hours in Low Earth orbit. Scott then spent ten days in orbit as Command Module Pilot aboard Apollo 9, his second spaceflight, along with Commander James McDivitt and Lunar Module Pilot Rusty Schweickart. During this mission, Scott became the last American to fly solo in Earth orbit (not counting subsequent untethered EVAs). Scott made his third and final flight into space as commander of the Apollo 15 mission, the fourth human lunar landing, becoming the seventh person to walk on the Moon and the first person to drive on the Moon.

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.

Robert Schumann, sometimes known as Robert Alexander Schumann, (8 June 1810 – 29 July 1856) was a German composer, aesthete and influential music critic. He is regarded as one of the greatest and most representative composers of the Romantic era. Schumann left the study of law to return to music, intending to pursue a career as a virtuoso pianist. He had been assured by his teacher Friedrich Wieck that he could become the finest pianist in Europe, but a hand injury ended this dream. Schumann then focused his musical energies on composing.

Schumann's published compositions were written exclusively for the piano until 1840; he later composed works for piano and orchestra; many Lieder (songs for voice and piano); four symphonies; an opera; and other orchestral, choral, and chamber works. Works such as Kinderszenen, Album für die Jugend, Blumenstück and Albumblätter are among his most famous. His writings about music appeared mostly in the Neue Zeitschrift für Musik (New Journal for Music), a Leipzig-based publication which he jointly founded.
