Foreshadowing

Shetterly briefly introduces Katherine Coleman Goble Johnson as the granddaughter of friends of Dorothy Vaughan’s. Shetterly mentions that she was a lot like Dorothy in that she graduated from high school at the age of 14 and was skilled at mathematics. Her importance to the work done at Langley is foreshadowed when Shetterly mentions that she would one day move to Newport News just as Dorothy did.
