"I have frequently been questioned, especially by women, of how I could reconcile family life with a scientific career. Well, it has not been easy."

"A scientist must be a child. He must be curious. He must be eager to learn. He must be willing to make mistakes."

"I believe that every woman who has a scientific career should be able to combine marriage with her work."

"I had to work for my living, and I had to study. It was a very hard time for me."

"You must never be fearful about what you are doing when it is right."
