It was Roald Dahl. I remember this becasue it was the same day as my mom's birthday. Roald Dahl was born on September 13th, 1916, in Llandaff Wales, UK.
That would be True (as seen by the original poster of the question). Negative space means an unoccupied area in a just definition. It would refer to the background of the image.
Hope this helps.
