DKMS began with one family’s search for a bone marrow donor. In 1990, Peter Harf was dedicated to find a donor match for his wife, Mechtild Harf. He registered 68,000 potential donors in Germany in a single year. Sadly, Mechtild lost her battle with leukemia, but in her honor, Peter started DKMS, which has since grown to become the world’s largest bone marrow donor center. In 2004, Peter and his daughter, Katharina Harf, established Delete Blood Cancer DKMS in the United States to continue to grow the international bone marrow donor registry and save more lives. Today, DKMS has branches in the U.S., Germany, the U.K., Poland, Spain and India.
