Offprint from Utr. Prov. en Sted. Dagblad, 1881, 20pp., original wrappers, Pieter Harting (27 February 1812 – 3 December 1885) was a Dutch biologist and naturalist, born in Rotterdam. He made contributions in a number of scientific disciplines, and is remembered for his work in the fields of microscopy, hydrology, botany, and biostratigraphy.Throughout his career he maintained an avid interest in the historical development of the microscope and in the manufacture of lenses. He is credited with making design improvements to the microscope, and was the author of a landmark book on microscopy that was translated into several languages, including German (Das Mikroskop, 1859 by Friedrich Wilhelm Theile).[3] At Utrecht he established a popular microscopy laboratory for students.In the field of hydrology he conducted extensive scientific groundwater research in an effort to improve the quality of water for public health. In collaboration with other scientists he formed the first committee for creation of a geological map of the Netherlands. The settlement of Hartingsburg in the Transvaal was named in his honor (later renamed Warmbad), as is a species of squid, Architeuthis hartingii.
