Sorby, Henry Clifton

born May 10, 1826, Woodbourne, near Sheffield, Yorkshire, Eng.
died March 9, 1908, Sheffield

British amateur scientist.

Convinced of the value of the microscope to geology, Sorby began in 1849 to prepare thin sections of rocks, about 0.001 in. (0.025 mm) thick, for microscopic study. He developed a new type of spectrum microscope for analyzing the light of organic pigments (1865). His research on meteors led to studies of iron and steel, and his later studies included the origin of layered rocks, weathering, and marine biology. He published works dealing with the physical geography of geologic periods, rock breakdown and buildup, and the formation of river terraces. Sorby is considered the father of microscopical petrography and metallography.

▪ British geologist
born May 10, 1826, Woodbourne, near Sheffield, Yorkshire, Eng.
died March 9, 1908, Sheffield

      English geologist whose microscopic studies of thin slices of rock earned him the title “father of microscopical petrography.”

      Sorby's early investigations were concerned with agricultural chemistry, but his interests soon turned to geology. He published works dealing with the physical geography of geologic periods, rock denudation and deposition, and the formation of river terraces.

      Convinced of the value of the microscope as a tool in all sciences, Sorby began to prepare thin sections of rocks (about 0.025 millimetre, or 1/1000 inch thick) for microscopic study in 1849. His subsequent findings demonstrated the value of petrography, the descriptive branch of the study of rocks. In his memoir “On the Microscopical Structure of Crystals,” in the Quarterly Journal of the Geological Society of London (1858), he championed the use of microscopic techniques in geology.

      In 1865 Sorby announced a new type of spectrum microscope for analyzing the light of organic pigments, especially minute bloodstains. His research on meteoric geology led to studies of iron and steel, and he concluded that steel is a crystallized igneous rock. His later studies included the origin of stratified rocks, weathering, and marine biology.
