The New Student's Reference Work/Celsius, Anders

Celsius (sĕl′sĭ-ŭs), Anders, a Swedish astronomer, born 1701, died 1744. Besides making some important geodetic measurements, he invented a scale of temperatures, known as the centigrade scale, which is now universally used in scientific work. The centigrade scale is defined by dividing the interval of temperature between melting ice and boiling water into 100 equal parts.
