Dr Ruth Pfau, a German doctor and nun who was popularly known as Pakistan’s ‘Mother Teresa’ for dedicating her life to healing leprosy patients, died at a private hospital in Karachi. She was 87. She died after a prolonged age-related illness. Pfau first visited Pakistan in 1960 and was so touched by the plight of leprosy victims that she decided to stay forever in the country. She founded Marie Adelaide leprosy Centre in 1962 and later set up its branches in all provinces of Pakistan.
