IQ stands for Intelligence Quotient. It is a score that combines the mental age of a person with his chronological age. For testing purposes, the mental age is determined by a series of standardized test questions, known as the IQ test. It is estimated that well-known scientist Albert Einstein had an IQ of 160 or more.
In the 20ies scientists had tried to estimate the IQ of deceased personalities such as Mozart (1756-1791) and Goethe (1749-1832) by means of biographic data; thus they wanted to estimate Albert Einsteinâs IQ, too.
