Hermann von Helmholtz (1821-1894)

"The true
scientist must always have something of the vision of an artist, something of
the vision which led Goethe and Leonardo da Vinci to great scientific thoughts.
Both artists and scientists strive, even if in different ways, toward the
goal of discovering new uniformities or lawful regularities.
... The true artist and the true scientist both know how to work
steadily and how to give their work a convincing, truthful form."--- Helmholtz,
from
speech given at the Commemoration-Day Celebration of the Frederick William
University in Berlin, August 3, 1878.
