All my life through, the new sights of Nature made me rejoice like a child.

I never see what has been done; I only see what remains to be done.

My husband and I were so closely united by our affection and our common work that we passed nearly all of our time together.

A scientist in his laboratory is not a mere technician: he is also a child confronting natural phenomena that impress him as though they were fairy tales.

More and more, I feel the need for a house and a garden.

After all, science is essentially international, and it is only through lack of the historical sense that national qualities have been attributed to it.

I have no dress except the one I wear every day. If you are going to be kind enough to give me one, please let it be practical and dark so that I can put it on afterwards to go to the laboratory.
