Google paid tribute to Dr. Ruth Pfau, the late doctor and nun who dedicated her life to fighting leprosy in Pakistan, with a scribble on her 90th birthday on Monday.
The drawing represents the German-Pakistani doctor, who died at the age of 87 in Karachi in August 2017, attending to a patient.
In describing the scribble, Google said it was being honored because "it was dedicated to eradicating the leprosy of Pakistan, saving countless lives."

"Also known as Hansen's disease, leprosy is caused by a bacterial infection that can now be prevented and cured, but the disease has historically caused patients to be excluded and stigmatized by disfigurement," he said.
The tech giant said that due to Pfau's persistent and disinterested efforts, the World Health Organization declared leprosy under control in Pakistan in 1996, before most other Asian countries.
Google, based in Mountain View, California, frequently changes the colorful logo on its famous Spartan homepage to celebrate anniversaries or important events or pay tribute to artists, scientists, statesmen and others.
A remarkable legacy
Dr. Pfau, who was a German by birth, had been sent to Pakistan in 1960 by the Daughters of the Heart of Mary, a congregation of nuns of which she was a member, for a medical service for students.
After witnessing the difficult situation of leprosy patients, he decided to settle here. He was granted Pakistani citizenship in 1988.
One of the founders of the Marie Adelaide Leprosy Center (MALC) in Karachi, Pfau managed to establish a network of 157 medical centers that served thousands of people.
In 1979, he received the Hilal-i-Imtiaz prize, the second most important civil award in the country. In 1989, Dr. Pfau was introduced to Hilal-i-Pakistan for her services.
