To help me identify the person you're thinking of, could you provide more context? For example:
* What field of education are you interested in? (e.g., early childhood, higher education, specific subject areas)
* What time period are you interested in? (e.g., 18th century, 20th century)
* Do you have any other information about this person? (e.g., their nationality, profession, any famous works or achievements)
With more information, I can assist you in identifying the correct individual and understanding their contributions to education.
