William Lash Miller

William Lash Miller, CBE, FRSC (1866 – 1940) was a Canadian chemist, chemistry professor, and pioneer of physical chemistry.

Lash Miller was born on 10 September 1866 at Galt, Canada West.

Lash Miller studied chemistry at the University of Toronto with bachelor's degree in 1887. He then studied from 1887 to 1889 under August Wilhelm von Hofmann, in 1889 under Viktor Meyer at the University of Göttingen, and in 1890 at the Ludwig-Maximilians-Universität München, where he received his doctorate in organic chemistry under Adolf von Baeyer. Subsequently, he studied with Wilhelm Ostwald at Leipzig University, which was a turning point in his chemistry career. From then on, he often spent summers in Ostwald's laboratory at Leipzig University. In 1891, Lash Miller became a demonstrator at the University of Toronto and was again in 1892 with Wilhelm Ostwald at Leipzig University, where he earned a second doctorate (in physical chemistry).

Lash Miller was considered one of the most important Canadian chemists at the time of his death. He built up the teaching of physical chemistry in Canada and was also one of Canada's first representatives of physical chemistry (and clinical biochemistry), with which he dealt from about 1915. With Ostwald, he devoted much of his scientific efforts to implement Gibbs' very theoretical concepts on a laboratory scale. Lash Miller did research on many areas of physical chemistry; in particular, he extended Gibbs' treatment of multicomponent systems.

Miller was elected to the Royal Society of Canada in 1899 and served as its President for 1934–1935. He was one of the main organizers of the Canadian Institute of Chemistry and was in 1926 its president. In 1926, he became the first Canadian honorary member of the American Chemical Society. He was a member of the editorial staff of the Journal of the American Chemical Society and of The Journal of Physical Chemistry A. He was made Commander of the Order of the British Empire in 1935.

Chemist William Lash Miller is not to be confused with lawyer William Miller Lash, his double cousin (first cousin on both sides).

He died on 1 September 1940 in Toronto.
