William Blake

 was an English poet, painter, and printmaker.

At his home in Cambridge in 1811, he fell through a hole in time and found himself trapped in the netherworld of the Yssgaroth. He met the Seventh Doctor when the Doctor went through another hole in the Althosian system.

They visited Whitechapel during the Jack the Ripper murders in 1888, and 20th century England. Eventually he was returned to his home via the Doctor's TARDIS. (PROSE: The Pit)

In 1783, Blake made an engraving of his brother Robert's painting Approach of Doom. (PROSE: The Adventuress of Henrietta Street)

Blake was one of the guests at Bernice Summerfield and Jason Kane's wedding in Cheldon Bonniface on 24 April 2010. (PROSE: Happy Endings)

While in Switzerland in 1963, the Fifth Doctor jokingly told Nyssa that he, along with Walt Whitman, might have been a Time Lord. (AUDIO: Winter for the Adept)
