In Fahrenheit 451, the main character is Montag. He is a fireman, a husband, and friend. First of all, I will be honest and say that I didn't like him very much at the beginning. He was this "bad guy" fireman. The fire department in this book is much different, instead of putting out fires, they start them by burning books. Basically, he just seemed like another fireman. But what I realized later was that he is a dynamic character. This means that he changes throughout the book. By the end of the book, he was more of a revolutionist I guess.
He worked outside the law so he could have knowledge from books that he stole and then hid in his house.
When I read this book, I picture a 30 year old guy that has a pretty wife, and a nice house in a utopian society. He had brown hair and blue grey eyes. I found a picture online that fits what I thought he looked like. Here he is.
