A Great Scientist is a Great Person in Civilization Revolution associated with science. Once a Great Scientist appears, they can either be settled in a city (where they will increase science production by 50%) or used to immediately finish any tech that is currently being researched. Like all other Great People, a Great Scientist acts as a non-combat unit with a movement speed of two squares per turn. Only one Great Scientist may be settled in a city. Moreover, settled Great Scientists can be kidnapped by enemy Spies.
