Background: David Robinson was born in Key West, Florida, the second child of Ambrose and Freda Robinson. Since Robinson's father was in the Navy, the family moved many times. After his father retired from the Navy, the family settled in Woodbridge, Virginia, where Robinson excelled in school and in most sports, except basketball. He was 5 feet, 9 inches tall in junior high school; he tried his hand at basketball, but soon quit.
Context: Robinson married Valerie Hoggatt in 1991. They have three sons, David Jr., Corey, and Justin. Corey attends Notre Dame and was a member of the football team, playing wide receiver, before ending his playing career on medical advice prior to what would have been his senior season in 2016 due to multiple concussions. He will remain very active on campus in his final undergraduate year, having been elected in February 2016 as student body president for the 2016-17 school year. Justin, a 6'8" (2.03 m) forward in basketball and a two-time all-state selection in Texas, has attended Duke since August 2015. He was initially recruited to the Duke team as a "preferred walk-on" with the opportunity to eventually earn a scholarship, but was placed on scholarship before his arrival at Duke.  Robinson identifies his religious affiliation as Christian. Robinson has stated that he became a Christian on June 8, 1991 after being encouraged to read the Bible.  In 2001, Robinson founded and funded the $9 million Carver Academy in San Antonio, a non-profit private school named for George Washington Carver to provide more opportunities for inner-city children. In 2012, the school became a public charter school and its name changed to IDEA Carver. Robinson continues to be a very active participant in the school's day-to-day activities.  In 2011, Robinson earned a Master of Arts in Administration (with concentration in organizational development) from the University of the Incarnate Word to better "understand how businesses work and how to build them.".  Beyond his founding of Carver Academy, Robinson is well known as a philanthropist. Robinson and business partner Daniel Bassichis donate 10 percent of their profits to charitable causes. The winner of the NBA Community Assist Award is presented with the David Robinson Plaque.
