On this day, 23 years ago, Audrey Hepburn passed away and the world lost an icon.

You know her face (and her style) from movies; you might not know that she was a globally-recognized humanitarian badass. Hepburn began working with UNICEF in 1954, and was appointed a Goodwill Ambassador in 1989. “I can testify to what UNICEF means to children,” she said. “Because I was among those who received food and medical relief right after World War II.“

To say that she dedicated herself to this role is a damn understatement. Hepburn travelled the world extensively, helping children in the most war-torn, drought-stricken, famine-ravaged areas, even during the last year of her life when she was sick with cancer. When she wasn’t traveling, she was giving press conferences, hosting fundraisers, and testifying before Congress. She used her fame to draw attention to crises that otherwise could go ignored — not because it made for a good photo op, but because it was the right thing to do.

On this day, when the world remembers Audrey’s beauty and grace, we should also remember her humanitarian work. UNICEF continues to help children all over the world; find out how you can support them here.
