John Gossweiler Explained

Johannes Gossweiler (24 December 1873,[1] [2] in Regensdorf  - 19 February 1952, in Lisbon[3]) aka John Gossweiler or João Gossweiler, was state botanist to the Government of Angola from 1899 until his death. He made important collections in every district of Angola and created the first phytogeographic map of that country. His collections of African plant specimens were sent regularly to Lisbon (Jardim Colonial[4] and Jardim Botânico da Universidade[5]), the British Museum,[6] the Royal Botanic Gardens, Kew,and the University of Coimbra.[7] Duplicates were also kept at the Herbarium of the Instituto de Investigação Agronómica[8] in Angola. Today, many herbaria contain specimens he collected (see

Biography

Gossweiler studied horticulture in Zurich, Stuttgart and Dresden, later spending four years in London at the Royal College of Science in South Kensington, and 1897-98 at the Royal Botanic Gardens, Kew. He was inspired by William Turner Thiselton-Dyer while at Kew, and went on to work for the government of Angola in the country's botanical garden in Luanda, where he remained until his death in 1952.

Arriving in Angola, Gossweiler found the garden far from complete, and started collecting in the coastal area around Luanda and the Malanje Plateau. In 1905 he studied the indigenous plant sources of rubber of the Cuando-Cubango[9] and Bié Plateau regions and collected many novel plants along the Okavango River.

The 'Cazengo Colonial Garden', the botanical garden of which Gossweiler would be director, was finally ready by 1907. Located on the site of an abandoned plantation, Gossweiler stocked it with indigenous species and plants from Sri Lanka, Goa, Malaysia and Tropical America. His collection of pressed specimens steadily grew. In 1915/16 he worked in Subliali, Pango Munga, the rainforest region of Mayombe, and near the source of the Zanza River, where he was accompanied by his wife Martha.

Following World War I Gossweiler worked for the 'Fomento Geral de Angola' from 1919 to 1926, during which time he made substantial collections along the southern bank of the Congo River, in the Dembos region and at Quiçama. In 1927 Gossweiler rejoined the government service and worked at starting an experimental cotton station in Catete, travelling to Amboim in 1932 to investigate coffee plant diseases. His collections grew with plants from the mist forest south of Cazengo. He then spent some time in Portugal at the University of Coimbra and the Colonial Garden in Lisbon, working on his collections.

Gossweiler embarked on two more collecting expeditions in Angola. In 1937-8 he joined a pair of Portuguese botanists, Luis Carrisso and F.A. Mendonça of Coimbra University, and Arthur Wallis Exell of the British Museum, on an extensive expedition covering some 13,000 km. On this expedition Carrisso suffered a fatal heart attack. Despite his death, work carried on, the results adding considerably to the 'Conspectus Florae Angolensis' of which the first volume, consisting of 55 parts, was published between 1937 and 1951.[10] The other expedition was in 1947 when he collected in the forests of Dundo in the far north-east of Angola.

Gossweiler's collections amounted to some 14,000 specimens, and are housed at some of the world's important herbaria. "J. Gossweiler 14685 (BM)", a specimen of Anticharis aschersoniana, may be the last he collected (July 1950) that is preserved.[11]

In 1936 Gossweiler's services were recognised by the Portuguese government, which awarded him the 'Comenda da Ordem do Imperio Colonial'. In 1950 he was elected a Foreign Member of the Linnean Society of London for his contributions to systematic botany.[12] [13]

Gossweiler died 1952 in Lisbon. In 1960, the Portuguese government granted his widow Marthe Gossweiler a life pension in recognition of his service to the country and for ceding his works to the country.[14]

A statue of Gossweiler is located in the park next to the regional museum of Dundo.[15] Two portraits of him were published in the 1950s.[16] [17]
