Charles H. Wood

He was employed in the study of quinine extraction in British India, where he was a Professor of Chemistry at the Medical College, Calcutta.

The process involved the use of fusel alcohol to extract the alkaloids, which were then precipitated as sulphates using sulphuric acid.

"Some time was necessarily spent in the preliminary work of analysing the various barks produced in the plantation, with the view of determining the influence of elevation, manure, &c, on them, and also in conducting experiments with the object of settling on the most advantageous mode of manufacturing an efficient febrifuge.

Around 1895, he married Rose Ada, 25 years his junior, and they had a son, Charles Edward Wood, born around 1898.
