Albert Einstein (1879–1955) German-born physicist and founder of the theory of relativity
In response to statement "You once told me that progress is made only by intuition, and not by the accumulation of knowledge."
Variant transcription from "Death of a Genius" in Life Magazine: "It is not quite so simple. Knowledge is necessary too. A child with great intuition could not grow up to become something worthwhile in life without some knowledge. However there comes a point in everyone's life where only intuition can make the leap ahead, without knowing precisely how.":
