Samuel Holker Haslam FLS (1797–1856), gentleman naturalist.

Samuel Holker Haslam (1797–1856) was an English naturalist whose plant and insect specimens are extant in several museum collections. Born into a family of cotton manufacturers in Lancashire, Haslam used his inherited wealth to set himself up as a country gentleman, eventually settling near Milnthorpe in Westmorland. He was a bibliophile, subscribing to several important fine colour-plate books on natural history and gardening, a Fellow of the Linnean Society of London and a member of many other societies spanning botany, entomology, palaeontology, agriculture and antiquarianism. He collected primarily in the Lake District (Westmorland, Cumberland and north Lancashire), West Yorkshire, Cheshire, Cambridgeshire, Gloucestershire, Somerset and the Channel Islands, especially Guernsey. His activities exemplify the role played by independent collectors in documenting early nineteenth-century British natural history. [ABSTRACT FROM AUTHOR]
