Sitting in Psych Class on the Forums

So today in my intro to psych class (I needed a social science elective) we are talking about the four humors of the body. I'm a biology major with a pre-professional concentration, and I cannot stand this lecture.

So, since I am in psych class, who is your favorite psychologist and why?

I'd say mine is Mary Ainsworth, just because she built upon the four different types of parenting styles. I'm interested in going into pediatrics or pediatric dentistry and the way a child develops and grows when influenced by parents is interesting to me.
