Word / Phrase request for someone who loves to propagate education among others

I am looking for a English word or phrase which suits someone who love to propagate education among people by establishing educational institutions or writing books and so on.

In order to translate a text from my mother tongue to English I need such a word but I can not find it so far as I have knowledge about English.I have tried to use some words(for example devoted) for this purpose but they seem inappropriate to me.

Solution 1:

educationist TFD or educationalist

an expert in the theory and/or methods of education.

Solution 2:

I'm not entirely sure a single word would do. 'Enthusiast' certainly fits, but you might want to qualify it further with the subject that enthuses them, such as 'educational/education enthusiast'.

Solution 3:

Pedagogue can have negative connotations, but depending on the context it might work for you.

Solution 4:

Preceptor is an oft-neglected age-old word that can be used. I'd also suggest educationalist.
