Temple Grandin wasn't officially diagnosed with autism until she was in her 40s, but knew at an early age she was different from her family and classmates. She only felt comfortable when spending time with the animals on her aunt's ranch. But instead of seeing her differences as limitations, Temple used them to guide her education and career in animal science. She has become a leading advocate for the autistic as well as for the humane treatment of animals at meat packing companies.
