Theodore William Richards (1868-1928), the first American to be awarded the Nobel Prize in chemistry, received it for his accurate determinations of atomic weights—twenty-five in all, including those used to determine virtually all other atomic weights. His work, which he began publishing in 1887, corrected earlier studies done in the 1860s by Jean Servais Stas. Among other contributions, Richards provided the experimental verification of the isotope concept, showing that lead from different sources has different atomic weights. Richards was educated at home by his mother, a Quaker author and poet, and his father, a noted painter of seascapes, until he went to Haverford College at the age of fourteen. He proceeded to Harvard, where he earned a doctorate in chemistry by the time he was twenty. He remained there as an important researcher and teacher, except for two sojourns in Europe—first on a prize fellowship and, much later, to learn about the latest developments in electrochemistry and thermodynamics to pass on to his students.

Theodore William Richards Theodore William Richards American chemist whose research on the atomic weights of approximately 60 elements indicated the existence of isotopes and earned him the 1914 Nobel Prize for Chemistry. Richards graduated from Haverford College, Pa., (1885) and took advanced degrees at Harvard University, where he became instructor in chemistry in 1891 and full professor in 1901. Richards greatly improved the technique of gravimetric atomic weight determinations, introducing quartz apparatus, the bottling device, and the nephelometer (an instrument for measuring turbidity). Although the atomic weight values of Jean Servais Stas had been regarded as standard, about 1903 physicochemical measurements showed that some were not accurate. Richards and his students revised these figures, lowering, for instance, Stas's value for silver from 107.93 to 107.88. Richards' investigations of the atomic weight of lead from different sources helped to confirm the existence of isotopes. His later researches were concerned mainly with the physical properties of the solid elements and included much original work on atomic volumes and compressibilities.

Theodore William Richards was born in Germantown, Pennsylvania, USA on January 31, 1868. His father, William T. Richards was a well-known painter of landscapes and seascapes: his mother, Anna, Matlack, won fame for her poetical works. During his childhood, Richards travelled to England and France and, up to the age of fourteen, he was educated by his mother. In 1883 he entered Haverford College , Pennsylvania, to graduate in science in 1885 and enter Harvard University About half of Richards' original work has concerned atomic weights, starting in 1886 with work on oxygen and copper. He quickly developed a new technique for the determination of halide ratios and did much towards improving methods of weighing. He invented the nephelometer and demonstrated the insidious effect of occluded moisture in gases and solids. By 1912 he had redetermined, with the highest accuracy, the atomic weights of over thirty important elements and in later years he was to play his part, by his work on the determination of the atomic weight of isotopes, in the modern concept of the atom. During his initial work he was guided by J.P. Cooke. Richards also studied atomic and molecular volume and he formulated a hypothesis of compressible atoms. He carried out a series of measurements of compressibilities of many elements and compounds in support of his theory, developing, applying and testing new methods and techniques. He introduced the use of transition temperatures of pure hydrated salts as fixed points in the standardization of thermometers, and the fundamentals of adiabatic calorimetry were developed under his guidance. His researches are recorded in some three hundred technical papers published mainly in the
