Amos Langdown, who was born at Plettenberg Bay in 1930, initially studied privately under the guidance of Katherine Harries. In 1961 a solo exhibition in Cape Town earned him a bursary from the Cape Three-Century Foundation, and during 1963-64 he furthered his studies at the Rijks Academy in Amsterdam, especially with regard to a large number of painting techniques. In 1988 he completed a BA degree at the University of Port Elizabeth.
He worked in various media, but showed a preference for oil painting. His paintings show a deep understanding of and sympathy for the people and events in the world surrounding him. The artist participated in various international exhibitions, for example Munich, Germany, The Venice Biennale in Italy and the Sub-Saharan African Exhibition that toured USA for a year. All the works in the latter exhibition were eventually sold and can be seen at the Smithsonian Institute in Washington. His works also forms part of several overseas and local collections, and his many solo exhibitions included one at the University of Port Elizabeth in 1988.
