Luis Ruiz Suárez S.J. (September 21, 1913 – July 26, 2011) was a Spanish-born Jesuit priest and missionary to China. Father Ruiz founded Casa Ricci Social Services, and later the Caritas Macau charity. His work in the 1950s focused mainly on refugees from mainland China. As Casa Ricci's works developed, it spawned Caritas Macau and Ruiz turned the focus of Casa Ricci to work with lepers and their families, and still later to those suffering from HIV/AIDS. He came to be known by several nicknames – "Luk Ngai" (in Cantonese), "Father of the Poor", and "Angel of Macau." Early life Luis Ruiz Suarez was born in Gijón, Asturias, Spain, on September 21, 1913. He joined the Society of Jesus, also known as the Jesuits, in 1930. As a young Jesuit he taught at Belen College in Cuba, where he had Fidel Castro as one of his students. Then in 1941 the Jesuits sent him to China as a missionary. He studied Mandarin Chinese in Beijing and philosophy in Shanghai. He was forced to cease his work due to the escalation of World War II and the Japanese occupation of China. After 1945 his superiors stationed him in Xian County in Hebei province. He was arrested, briefly imprisoned, and expelled from the newly formed People's Republic of China in 1949 following the Chinese Communist Revolution. While in prison, Ruiz contracted typhoid before his expulsion from China. He left China for Hong Kong in 1951. Macau, Casa Ricci Social Services, Caritas Macau In 1951, Ruiz's Jesuit provincial sent him to Macau, a Portuguese colony along the southern Chinese coast, to recover from his typhoid; he would be based there for the rest of his life. The roots of Jesuit social work in Macau go back to 1569 when Melchior Carneiro, the first bishop of Macau, founded there the first Western-style hospitals in Asia. Ruiz's first major work was with refugees fleeing from the People's Republic of China. He used the official Jesuit residence in Macau, which was called Casa Ricci, as a temporary shelter for the mainland Chinese refugees. This led to the establishment of Father Ruiz's first charity in Macau, the Ricci Center for Social Services, which offered a variety of social services. The center furnished refugees with housing, educational opportunities, documentation, child care, and employment. For their children the centre set up the Colegio Mateus Ricci School and the Escola
