Jan Kurzke was a left-wing artist who fled Nazi Germany in the early 1930s and tramped round the south of Spain, witnessing first-hand the poverty of the rural population.
Many of his fellow volunteers died in the savage battles on the outskirts of Madrid and Jan himself was seriously wounded at.
When the Spanish civil war broke out in 1936, he went back and joined the International Brigade, to defend the democratically elected Republic.
He eventually found his way to London.
