“Chris Jahnke was family, and we will never fully recover from her passing. She taught hundreds of women to find their own voices, and to be louder and clearer in their messages. She was a fierce advocate for representation, inclusion, and equality, and she left the world a better place for it,” the Women’s Media Center said in a statement on the group’s Twitter page.

“There was true joy on her face as you went through training and you’d see a trainee get it and connect and suddenly the skills kick in, along with the comfort level and the confidence,” Julie Burton, president of the Women’s Media Center, said in an interview. “She not only transformed what a person could do, she transformed a movement.”

Julie Burton, president of the Women’s Media Center founded by Jane Fonda, Robin Morgan and Gloria Steinem, estimated that Ms. Jahnke had trained 70 percent of the women who have attended the center’s media training programs.
