Crum Brown was born in Edinburgh on 26th March, 1838, his father being Dr. John Brown (1784-1858), minister of Broughton Place United Presbyterian Church. Dr. John Brown was twice married. His son by the first marriage was John Brown, M. D. (1810-1882), well known as an Edinburgh physician, but who earned a wider fame as the author of Rab and His Friends, Horæ Subsecivæ , and other literary essays. Crum Brown, the only son of the second marriage, was named after his maternal grandfather, Alexander Crum, of Thornliebank, a merchant and manufacturer of Glasgow. His mother’s brother, Walter Crum, F. R. S. (1796-1867), was a chemist of note, and it is probably due to the influence of this uncle that Crum Brown’s thoughts were specially directed to chemistry amongst the various subjects of his university studies. Crum Brown’s education was received in the Royal High School, Edinburgh, where he spent five years, followed by one year at Mill Hill School. In 1854 he entered the University of Edinburgh, where he graduated as M. A. in 1858 in London University, and in 1862 he had the distinction of being the first candidate on whom the Doctorate of Science of the University of London was conferred. After his graduation as Doctor of Medicine in Edinburgh he pursued the study of chemistry in Germany, first under Bunsen at Heidelberg, and then at Marburg under Kolbe. In 1863 he was licensed as an Extra-academical Lecturer in Chemistry by the University of Edinburgh, and in 1869 he succeeded Lyon Playfair in the Chair of Chemistry at the University, holding office till his retirement in 1908.
