Fighting for animals, people and the environment... since 1983

Marilyn Kroplick MD is president of In Defense of Animals, a board-certified psychiatrist, and award-winning socio-political photographer.

Since 2011, Dr. Kroplick has led In Defense of Animals’ powerful campaigns to end the dog meat trade, advocate for elephants, strengthen animal cruelty laws, and save animals in need around the world. Her groundbreaking program to mentor and support animal activists marries support for humans and animals alike.

Her passion for animal rights was ignited in 2002 after purchasing a puppy from a pet store who became terribly sick. Dr. Kroplick’s fight for justice led her to discover the system of abuse that brings puppies to pet stores, and successfully expose and shut down the offending pet store.

Dr. Kroplick is using her extensive expertise to build a supportive and inclusive social change movement to achieve animal liberation through sustainable activism.

Our Founder

Dr. Elliot Katz DVM founded In Defense of Animals in 1983.

In early 1983, veterinarian Dr. Elliot Katz was contacted by animal activists and discovered scandalous conditions inside UC Berkeley’s animal laboratories — an event that changed animal protection history. Living in cramped and filthy facilities, animals were sick and dying while campus veterinarians were prevented from providing treatment to those in need.

Dr. Katz formed Californians for Responsible Research, which filed a lawsuit against USDA, forcing them to issue a cease and desist order against UC Berkeley. Ultimately, Berkeley was fined $12,000 for violating the Animal Welfare Act. Californians for Responsible Research was renamed In Defense of Animals, and for over 33 years it has become a force to reckon with — foremost in animal advocacy.

Dr. Katz passed away in March, 2021. Learn more about how this animal rights trailblazer changed the world for animals.
