In 1949, St Thomas's Hospital Medical School was granted its own coat of arms. However, the St Thomas' Hospital coat of arms has still been used. Guy’s Medical School proposed to apply for its own coat of arms after separating from Guy’s Hospital, yet the school decided to continue to use Guy's Hospital’s arms in 1954. The two medical schools merged in 1982 and became the United Medical and Dental Schools of Guy's and St Thomas' Hospitals (UMDS). Simon Argles, secretary of UMDS, said that because of the name of the medical school it was more appropriate to use the hospital's coat of arms.
