In the 18th Century the utilitarian philosopher Jeremy Bentham came up with his idea of the Panopticon, a prison building with a central tower encircled by cells so that each person in the cells knew they could be watched at all times. Whether they were observed or not was actually immaterial. Bentham called it ‘a new mode of obtaining power of mind over mind’ and while he focused on its use as a prison, he was also aware of the idea’s usefulness for schools, asylums and hospitals. Bentham got the original idea following a visit to Belarus to see his brother who was managing sites there and had used the idea of a circular building at the centre of an industrial compound to allow a small number of managers to oversee the activities of a large workforce. This is something of a precursor of the scientific management theories of Frederick Taylor that continue to influence the way we work and manage people.
