Question

who is the strong character in david Copperfield

Answer 1

Doctor Strong is the headmaster of David's second, much better, school. Unlike Mr. Creakle, he has no trouble keeping order because all of the students respect and love him. He treats them all like his children, and they respond with an admiring, protective affection that Dickens seems to feel is appropriate for students to have for their teacher. 

Always distracted from the world around him by his lofty thoughts, Doctor Strong is like the stereotypical absent-minded professor. His current project is a new dictionary. He's always carrying bits of the dictionary with him so that he can add things as he thinks of them.

Strong is married to a lovely woman much younger than himself named Annie. Annie was actually also originally a student of Doctor Strong's. Doctor Strong had been a friend of her late father. When she left his tutoring, he came to her mother and asked for permission to marry her. Annie was flattered, and agreed.
