Ms. Grandin was born in Boston in 1947 and at a young age was diagnosed with autism. She began speaking later than most children and had difficulty interacting with others socially. If we consider autism to be enigmatic today, multiply that several times in the 50's and 60's when she grew up. Despite obstacles, Grandin graduated from high school and college, earning both a Master's Degree (1975) and a Doctorate in Animal Science (1989).
Something depicted well in the HBO Film Temple Grandin was the way in which her high school science teacher helped her conceptualize her future in college. Dr. Carlock said to her:
"Think of it as a door. A door that is going to open up onto a whole new world for you. And all you
need to do is decide to go through it."
Several times in the film, Temple Grandin needs to go through a scary door to get to the new world she will become part of--from the frightening automatic door at the grocery store that reminds her of a guillotine to the door of a slaughterhouse she will ultimately redesign to be more humane and the cinematic door she walks through to speak publicly about autism at a national conference.
Temple Grandin is an individual who has been tremendously influential in the area of treatment of animals at slaughter facilities by using her visual mind and attention to detail. As she heroically stepped through various doors, she also extended "the horizons of the possible"  for many others.
