Peter MacOwan

From Wikipedia, the free encyclopedia

Peter MacOwan born Hull, England on 14 November 1830 - died Uitenhage, Cape Province 30 November 1909, was a colonial botanist and teacher in South Africa.

He was the son of Peter McOwan, a Wesleyan Minister from Scotland, and changed his name at some stage. After finishing school he taught at Bath, Colchester and Leeds, and in 1857 taught chemistry at the Huddersfield College Laboratory. That same year he graduated in chemistry from London University, becoming Professor of Chemistry at Huddersfield. The year before, he married Amelia Day from Bristol. A severe lung condition, possibly asthma, caused him to move to South Africa and take up the post of principal at the newly established Shaw College in Grahamstown. His health rapidly improved and leaving chemistry behind he resumed studying botany in which he had become interested while still in England, having started a collection of flowers and mosses. This interest was furthered by his association with Dr Willian Guybon Atherstone, Henry Hutton and Mrs. FW Barber. He entered into a fruitful exchange of specimens and correspondence with Asa Gray of the States, Sir William Hooker of Kew and with Harvey and Sonder who were working on the Flora Capensis. Finding it a drain on his own time to supply duplicates to overseas collectors, he formed the South African Botanical Exchange Society, which brought together a large number of amateur botanists. By 1868 roughly 9000 duplicates had been sent abroad, for which in return they received specimens from Europe, North America and Australia. His contributions are acknowledged in the introductions to Flora Capensis. He assisted Atherstone and HG Galpin in confirming in 1867 that the Hopetown or Eureka diamond was indeed a diamond. Eventually he became head of natural sciences at Gill College, Somerset East, South Africa and then later director of the Cape Town Botanical Garden and curator of the Cape Government Herbarium. Peter MacOwan's daughter Flora married Selmar Schonland in 1896.

Plant pathology as a science in South Africa formally began in 1887 with the appointment of Peter MacOwan as the consultant in economic botany to the Cape Government.^[1]
