He worked in his father’s drapery and grocery business in Thirsk for several years (many of the Baker H@H sheets are from Thirsk and the surrounding area). It was home of the ‘Thirsk Botanical Exchange Club’ for some 8 years (derived from the London Botanical Society). But in 1864, the Baker premises were consumed by fire. The family lost their home and shop, and Baker his botanical library, herbarium specimens and the reports / records of the Thirsk botanical society.
After a stay with William Borrer in Sussex, J D Hooker invited him to take up a position at Kew, so he worked in the herbarium there as initially as First Assistant.
He also acted with Trimen as joint Curator of the London Botanical Exchange Club, and they also edited The Journal of Botany. He worked at Kew for many years and from 1890 – 99 was Keeper. He published a Flora of Mauritius and the Seychelles, a Flora of the Lake District and a Flora of Northumberland and Durham (?).
Many of his labels on the specimens at H@H have various annotations such as lacustral medapor. In fact, the latter ‘translates’ to mid-agrarian. It is part of a system of environmental / habitat classifications associated with H C Watson of ‘vice counties fame’. Further detail can be found in his Cybele Brittanica.
