"You asked what kind of army we are. Cleveland Amory once said it. He said, "the army of the kind." And that's it. If there's anything going on, we find it irresistible not to speak out, to do something, to say something, to enlist other people to help because we're not some superhuman force, we're a collection of humans." Ingrid Newkirk

Ingrid Newkirk co-founded People for the Ethical Treatment of Animals (PETA) in 1980, and since then, I don't think there has been a single day that she has not fought against injustice toward animals. She is not only a hero for millions of animals but also for humans, for showing all of us how to make change happen and for inspiring us to do it.

Since it was founded, PETA has exposed horrific animal abuse in laboratories, leading to many firsts, including canceled funding, closed facilities, seizure of animals, and charges filed by the U.S. Department of Agriculture. PETA has also closed the largest horse-slaughter operation in North America, convinced dozens of major designers and hundreds of companies to stop using fur, ended all car-crash tests on animals, helped schools switch to innovative animal-free dissection tools, and provided millions of people with information on being vegan, companion animal care, and countless other issues.

Ingrid just celebrated her 75th birthday, so we got together to take a look back at her life and the life of PETA.

Happy Birthday, Ingrid!
