Without a firm base, the Club met at various venues in addition to the Franklin home, including the Medical Society of London, Wellcome Institute, the Royal College of Surgeons, and the Royal College of Physicians (RCP). In 1949, the annual dinner was held at the Royal College of Surgeons. In 1957, the Club met at the Medical Society of London. A substantial bequest from the estate of cardiologist Thomas Forrest Cotton enabled the Club to secure a permanent home when the RCP's dining room was named the Osler Room, and the Thomas Cotton Room was established to store the library, archives, and other possessions of the Club. Along with this, the RCP permitted use of their premises for Club events. The Club meets on average once every two months, when a members' paper is presented, consisting of original research on the history of medicine and associated subjects. Reflecting Osler's humanistic approach, topics are not solely confined to the history of medicine, and past contributions have touched on ethics, law, and modern changes affecting society and medicine. At the annual general meeting in 1970, Dr Norah Schuster presented a talk on "That Picture", a portrait of Alexander, Emperor of the Russias, painted by James Northcote in 1820. Meetings are carried out under Chatham House Rules whereby members are free to use anything heard at the meeting but are not allowed to reveal its source. There are Osler clubs in the United States, Canada, Japan, Argentina, and elsewhere around the world.
