The Harveian Society of Edinburgh was founded in April 1782 by Andrew Duncan. The Society holds an annual Festival in honour of the life and works of William Harvey, the physician who first correctly described the manner in which blood circulates around the human body. Until 1829, the Society was known as the Circulation Club or the Harveian Club. Membership of the society is by invitation and members are doctors based primarily in Scotland. There are currently over 140 members, who are known as "Harveians".
