Totais (incluindo 4 fundadores):
24 - Unknown (including 3 unnamed Headmasters)
7 - Unknown and not even 100% were in Hogwarts despite title Professor
6 or 8 - Slytherin (Carrows were unknown but likely S)
6 - Gryffindor (3 of them during Harry's time)
5 - Ravenclaw
2 - Hufflepuff
1 - Didn't attend Hogwarts (Firenze)
1 - Non-Slytherin (unknown otherwise)
Notas:
-
Em 2 casos - Carrows - a casa não é conhecida do cânone, mas pode ser facilmente adivinhada.
-
Eu também teorizaria que o professor de Aritmancia provavelmente era da Corvinal, apesar de ser listado como desconhecido oficialmente.
-
4 pessoas listadas são os diretores de Hogwarts sem 100% de informação canônica de que eram professores. Puramente teoricamente, é possível que eles tivessem ocupado o cargo sem serem professores.
-
Eu listei Alastor Moody e Barty Crouch Jr como pessoas separadas. Alastor nunca ensinou enquanto Barty não fosse convidado para ser professor.
Detalhes:
Aqui está uma lista de todos os professores listados no HP Wikia, provenientes de aqui e aqui .
Eu já os coloquei em casa, se forem conhecidos.
Eu não me incomodei em incluir os 4 fundadores nesta lista, mas incluí-los nos totais acima.
