What is a biography?
It is an account of a person's life written by someone else. It should not be confused with an autobiography, which is a person's own account of their life, written by him or her.
To write a good biography, you'll need to take notes about the person you are writing about. This means reading a few books about the person. You'll need information on the following:
Early life
Childhood
Adulthood
Hometown/country
Path to fame
Current life (if they're still alive)
Later life (if they're no longer alive)
Your feelings about the person
