David C. McClelland (May 20 1917 – March 27 1998) was an American psychological theorist. Noted for his work on need theory, he published a number of works from the 1950s until the 1990s and developed new scoring systems for the Thematic Apperception Test and its descendants. McClelland is credited with developing the Achievement Motivation Theory commonly referred to as need achievement or n-achievement theory.

David Clarence McClelland, born in Mt. Vernon in New York State, was awarded a bachelor of arts from Wesleyan University in 1938, and an MA from the University of Missouri the following year. He received his PhD from Yale University, and taught at Connecticut College and Wesleyan University before joining the faculty at Harvard University in 1956, where he worked for 30 years, serving as chairman of the Department of Social Relations. He moved to Boston University in 1987. Here, he was awarded the American Psychological Association Award for Distinguished Scientific Contributions.

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.
