Kareem Abdul-Jabbar (born Ferdinand Lewis Alcindor Jr.; April 16, 1947) is an American retired professional basketball player who played 20 seasons in the National Basketball Association (NBA) for the Milwaukee Bucks and the Los Angeles Lakers. During his career as a center, Abdul-Jabbar was a record six-time NBA Most Valuable Player (MVP), a record 19-time NBA All-Star, a 15-time All-NBA selection, and an 11-time NBA All-Defensive Team member. A member of six NBA championship teams as a player and two as an assistant coach, Abdul-Jabbar twice was voted NBA Finals MVP. In 1996, he was honored as one of the 50 Greatest Players in NBA History.

At age 24 in 1971, he converted to Islam and became Kareem Abdul-Jabbar, which means "the noble one, servant of the Almighty." He was named by Hamaas Abdul Khaalis. Abdul-Jabbar purchased and donated 7700 16th Street NW, a house in Washington, D.C. for Khaalis to use as the Hanafi Madh-Hab Center. Eventually, Kareem "found that [he] disagreed with some of Hamaas' teachings about the Quran, and [they] parted ways."  Speaking about the thinking behind his change of name when he converted to Islam he stated that he was "latching on to something that was part of my heritage, because many of the slaves who were brought here were Muslims. My family was brought to America by a French planter named Alcindor, who came here from Trinidad in the 18th century. My people were Yoruba, and their culture survived slavery...  My father found out about that when I was a kid, and it gave me all I needed to know that, hey, I was somebody, even if nobody else knew about it. When I was a kid, no one would believe anything positive that you could say about black people. And that's a terrible burden on black people, because they don't have an accurate idea of their history, which has been either suppressed or distorted."  In 1998, Abdul-Jabbar reached a settlement after suing Miami Dolphins running back Karim Abdul-Jabbar (now Abdul-Karim al-Jabbar, born Sharmon Shah) because he felt Karim was sponging off the name he made famous by having the Abdul-Jabbar moniker and number 33 on his Dolphins jersey. As a result, the younger Abdul-Jabbar had to change his jersey nameplate to simply "Abdul" while playing for the Dolphins. The football player had also been an athlete at UCLA.
