Dorothy Pitman Hughes, co-founder of Ms. Magazine, has died at 84.

According to CNN, her longtime friend and colleague, Gloria Steinem broke the news. The obituary says she “passed away peacefully” at the home of her daughter and son-in-law, Delethia and Jonas Malmsten on December 1 in Tampa, Florida.

She was 84 and is survived by three children and two grandchildren.

Hughes “organized a multiracial cooperative daycare center” in the late 1960s. This caught the attention of Steinem, with whom she would go on to help establish Ms. Magazine, a prominent, feminist magazine.

Steinem recalled being “lucky to call Dorothy a friend and lifelong co-conspirator” on an Instagram post.

“She encouraged me to speak in public, and we spent years traveling across the country. Her devotion to children's welfare, racial justice and economic liberation means that she left the world in a better place than she found it.”

Initially, Ms. Magazine was created in the 1970s as a “sample insert in New York Magazine.” On the website, it reads that the magazine would soon become a “landmark institution in both women’s rights and American journalism.”

Along with Ms. Magazine, Hughes and Steinem cofounded “the Women’s Action Alliance, a pioneering national information center that specialized in nonsexist, multiracial children's education, in 1971," the obituary reads.
