The second African-American justice to serve on the Supreme Court of America, the appointment of Clarence Thomas in 1991 was controversial. He was accused of sexual harassment by lawyer Anita Hill in public hearings, but was eventually cleared. He is on the conservative side of the court and has been criticised by liberals for opposing issues like gay marriage.

In 2005, a commemorative dollar was minted in his honor.
