Marty Delaney, founder of Project Inform and a prominent HIV/AIDS treatment activist, died on Friday, January 23, according to longtime friend and AIDSmeds senior writer David Evans. He was 63 years old.

“If there’s one thing that I think we can all do in gratitude for what Marty has done for all of us, it will be to make every effort to fill the massive void that Marty leaves behind,” Evans said.

Delaney founded Project Inform in 1985 with other concerned community members in San Francisco to provide reliable information about HIV/AIDS and its treatment. Today, it’s a national organization dedicated to improving the lives of people living with HIV/AIDS and their loved ones.

Delaney was recently honored with a Special Recognition Award by Anthony Fauci, MD, the director of the National Institute of Allergy and Infectious Diseases, for his leadership in the fight against HIV/AIDS.

According to a statement from staff and volunteers of Project Inform: "Intellect, activist, diplomat, mentor, friend—each of us will remember Marty for the great attributes he brought to his lifesaving work. We will miss him terribly."
