choose a person who was instrumental to your chosen/intended major. You will have to explain the importance of this person to your field and extrapolate the effects they had.
As you get further into your studies, you might change your major a few times, so don’t worry about being committed to any field you write about. For instance, I started as a psychology major before finding my love for English and education. Even if you are uncertain about your future plans, this paper is an opportunity to explore an area that currently interests you through the lens of someone important to that field.
This is not a biography. It is a research project focused on why your chosen person was essential to that field, such as medicine, education, engineering, nursing, legal, psychology, art, etc. You don’t need to go through their whole life but focus on their critical contribution(s).
Consider the following questions to help shape your paper:
-How did they come to make this contribution?
-What was the immediate impact of this contribution?
-What was the long-term effect(s) of this contribution?
