Who is the subject of “The Making of a Scientist”?

The story in short

Written by Robert W. Peterson, this inspiring account traces the journey of Richard Ebright, who grew from a curious boy into an outstanding scientist. As a child in Pennsylvania, Richard collected butterflies and showed great curiosity about the world. His mother encouraged his interest, giving him books, microscopes and learning materials and spending time with him. A turning point came when he tried to raise a flock of butterflies and entered science fairs; though his early projects taught him that mere display was not real science, he learned to ask genuine research questions. His investigations into the purpose of the gold spots on monarch pupae and later into how cells work led him to a new theory about how cells read their DNA. The chapter identifies the qualities behind his success: a first-rate mind, intense curiosity, the will to win for the right reasons, and the constant encouragement of his mother and teachers. It shows that great scientists are made through curiosity, hard work and proper guidance.
