Amos Langdown was born on 7 May 1930, in Plettenberg Bay. He was trained as a teacher at the Zonnebloem College in Cape Town and he first taught at a primary school in Oudtshoorn. During his life he maintained a very good balance between his two favourite things; teaching and art, which he taught at Cape Town and Port Elizabeth. Amos was awarded grants by both the Government and the Cape Tercentenary Foundation to study abroad, after his very successful first solo exhibition. During this time he was studying part-time at Michaelis School of Fine Art at the University of Cape Town, where Carl Buchner and Russel Harvey also taught. When looking at Amos`s work, the inspiration of fellow South African artist, Katrine Harries, is evident, especially in his lithographs. He was also greatly influenced by French artist, Honoré Daumier, but his work of the communities on the Cape Flats speaks heavily of sympathy and centiment. This is very evident in his paintings of groups of people.
He was also a poet in his own right and illustrated published writings of Alba Bouwer, Pieter Grobbelaar and P.J. Philander.
Amos passed away on 1 February 2006 in Overbaakens, Port Elizabeth.
