Brown, David, F.C.S., Manufacturing Chemist, was born in Edinburgh 
in 1840. He succeeded his father, Mr D. R. Brown, as senior partner of 
the firm of J. F. Maefarlan & Co. He was educated at the Royal High 
School, and studied Chemistry at the University of Edinburgh. For some 
time he assisted Professor George Wilson in Edinburgh, and afterwards 
Professor Anderson in Glasgow. At a later period he joined the staff of 
the Apothecaries’ Hall in London, thus gaining a knowledge of applied 
pharmacy. Thereafter he was engaged in the manufacture of chemical 
substances used in medicine. 
Though engrossed in the management of the business, Mr Brown was 
the author of several valuable papers on chemical subjects published in 
the Pharmaceutical Journal and elsewhere. Notes on Chloroform and 
on the location of Salicin in Willow Bark are among his published papers. 
Though he refrained from publishing anything on the opium alkaloids, he 
recognised oxy narcotine as an undescribed substance, and handed it over 
to Dr Wright, who made an analysis and gave the results to the Chemical 
Society. 
The preparation of salicin from willow bark was begun in Mr Brown’s 
time. He was a Justice of the Peace and a member of the Merchant 
Company in Edinburgh. 
Mr Brown was elected to the Fellowship of this Society in 1893, and 
died on 21st June 1921 at his residence, Willowbrae House, Edinburgh. 
His son, Mr Rainy Brown, died a few months earlier.
