William Pearson (1934 - 18 June 1995) was an American born baritone, who spent most of his career in Europe, especially in Germany.
He was notable for his wide repertoire, stretching from Bach and Handel to spirituals, modernist and avant garde compositions.
Pearson was born in Tennessee and studied at the School of Music at the University of Louisville, Kentucky.
After leaving the opera house, Pearson gave concerts and recitals around Germany, as well as in the major cultural centres in Europe.
Several modern composers wrote music for him, including György Ligeti (he was also one of the soloists in Ligeti's Aventures (1962)), Sylvano Bussotti (Pearson wrote the text himself for Bussotti's Pearson Piece (1960) for baritone and piano) and Dieter Schnebel, while he also recorded works by Hans Werner Henze and Mauricio Kagel.
