From Wikipedia article (Rabbi Aryeh Levin):
R' Aryeh Levin was also known for his visits to the sick, especially patients who had no family of their own. "It was Reb Aryeh's practice to go to the hospitals of Jerusalem every Friday, to visit the sick who were confined there. First he would always go and speak with the nurses, to find out from them which patients received no visitors as a rule. At the beds of these forgotten souls whom no relatives came to see, he would linger, caressing each one's hand and giving him words of encouragement and cheer. He would sit for hours near the beds of the sick, especially at Bikur Cholim hospital in Jerusalem."
"He was also a frequent visitor at hospitals for lepers, including a hospital in Bethlehem, where most of the patients were Arabs. Reb Aryeh began this holy practice after he had found a woman weeping bitterly by the Western Wall. Reb Aryeh asked her what made her cry so intensely. She told him that her child had no cure, and was locked up in the leper hospital in Jerusalem. He immediately decided to visit the young child, and when he arrived, all the patients burst into tears. It had been years, since they had the privilege to see any visitor from the outside world."
"His pious wife Chana Levin, cooked regularly for them, and he would take the prepared food to the hospital."
