Historical Background
The establishment of King Chulalongkorn Memorial Hospital was initiated by King Vajiravudh, who, together with his brothers and sisters, wished to repay his father's generosity. In the reign of King Chulalongkorn, His Majesty had given royal permission to set up the Red Unalom Society of Siam, the purpose of which was to offer examination and treatment to the sick in accordance with practices in other civilized nations. But as the predecessor of the Thai Red Cross Society had not fully reached the state of completion, King Vajiravudh and other sons and daughters of King Chulalongkorn deemed it necessary to continue their father's determination to help sick people in honor of the Kingdom of Siam. His Majesty King Vajiravudh and princes and princesses, sons and daughters of King Chulalongkorn, all donated their personal money and property to the Thai Red Cross budget for construction of a hospital. On May 30, 1914, His Majesty King Vajiravudh graciously presided over the opening ceremony of the hospital and gave permission to the Thai Red Cross Society to name the hospital after his father.
It was stated in the Thai Red Cross announcement dated May 1, 1914 that King Chulalongkorn Memorial Hospital had to strive to be a scientifially sound hospital in honor of King Rama V, King Rama VI, and the Kingdom of Siam. It would offer examination and treatment services to the injured and the sick so as to relieve the health care burdens of the authorities in time of peace and in time of war. It would strictly adhere to the credo to give help to the public regardless of ethnicity, social class and caste, sect and religion, or political affiliation. With the adoption of highly advanced technologies of science, medicine, and computer science and in collaboration with Chulalongkorn University's Faculty of Medicine, King Chulalongkorn Memorial Hospital has honored its stated aims and seen uninterrupted growth in terms of medical studies, research and personnel development.
In addition to offering examination and treatment services to the public, King Chulalongkorn Memorial Hospital also provides training facilities to domestic doctors of Chulalongkorn University's Faculty of Medicine and, through its School of Radiology, supplies medical personnel specialized in the field. The Hospital has been a center of academic excellence in various fields of medicine in Thailand and is determined to maintain the quality of its health care services in line with the motto "service-minded devotion to society."
