Professor Olivia Green was a witch who attended Hogwarts School of Witchcraft and Wizardry in the second half of the 20th century and was sorted into Ravenclaw. She was friends with Jacob, who was in her year.
During the 1988–1989 school year, Jacob's sibling found a letter written to Olivia Green from Jacob in Jacob's room, where Nicholas de Mimsy-Porpington informed them about her, and how according to him, possessed exceptional courage. He then told them to seek the Grey Lady for more answers about her.
Defence Against the Dark Arts Professor (1990–1991)
Sometime after her graduation, in the middle of the 1990–1991 school year, Olivia was appointed the school's new Defence Against the Dark Arts teacher as her predecessor left Hogwarts without a word. When she introduced herself to seventh-years at the start of a lesson in Classroom 3C, she told them that she wanted to be addressed as "Olivia" rather than "Professor Green".
