Please correct my mistakes if possible. To Build a Statue to Honor a Famous Person.

I like they built a statue a scientific person just like Dr. Holakuee.

I would like if they built a statue in honor of a scientist, like Dr. Holakuee.  

I like his personality because he has an affective personality on people. (Describe an affective personality. Do you mean contagious? Is it positive? Is it conducive to learning?)

I like him because he has a positive influence on people. <or>

I like his personality because it has a positive influence on people.

He is realistic and can help people when they are confused. He is a sociologist, economist and psychologist. He is a smart man and can rationally analyze issues. (good job here)

He really is a helpful scientist. He has a critical thinking. He has lived in USA since 36 years ago.
Anyone can correct me. I will be so grateful.

Building A Statue To Honour A Famous Person

I'm glad they built a statue of an academic like Dr. Holakuee. I like him as a person because his personality has a strong effect on people. He is pragmatic and can help people when they don't understand something. He is a sociologist, economist and psychologist. He is a smart man who can analyse a problem rationally. He is a really helpful scientist. He thinks critically. He has lived in the USA for 36 years. 

If anyone can correct my entry, I will be so grateful.
