many a teacher vs many teachers

[HaraKiriBlade]

One much talked-about educational theorist in the Rogersian tradition is the well-known Brazilian educator Paolo Freire (1970), whose seminal work, Pedagogy of the Opressed, has inspired many a teacher to consider the importance of the empowerment of students in classrooms.

I've seen this kind of construction before so I know it's not a grammatical mistake or a typo on the publisher's part. (Besides, I'm not proficient enough to point out mistakes made by publishers) But I don't know why the author chose to use 'many a teacher' as opposed to 'many teachers'. Can anyone provide an explanation for this?

Both mean the same thing...

many a teacher is a rather old way of writing and not used much any more.
