He is the founder of The Dui Hua Foundation, a nonprofit humanitarian organization that promotes universal human rights in well-informed, mutually respectful dialogue with China.
In an article about Kamm for The New York Times Sunday Magazine, Tina Rosenberg wrote: “No other person or organization in the world, including the State Department, has helped more Chinese prisoners.
[3] From 1991 to 1994—the year US President Bill Clinton unconditionally renewed China's MFN trade status, Kamm started doing advocacy work full-time.
In 1995, China's State Council Information Office and the Ministry of Justice agreed to receive from Kamm quarterly prisoner lists of up to 25 names and began providing written responses on many of the cases.
One such person who benefited from Kamm's interventions, Tibetan nun Ngawang Sangdrol, was the focus of Marie Louville’s documentary film, Prisoner in Lhasa.
Based in San Francisco, Dui Hua seeks clemency and better treatment for prisoners detained in China for the nonviolent expression of their rights to free speech and association.
