Clearing a bit of forest for his farm, near Lusaka, Zambia

The world was in turmoil in the late 1960s; it was the apartheid era in South Africa, the time of the Soviet invasion of Czechoslovakia, and of America’s war in Vietnam where war photographers Don McCullin and Larry Barrows made their names. There were civil rights movements about race and equality for women in the USA and, in France, students rioted. This was Structuralism, when society focused on structures and rules. For photography, it meant incorporating the concepts of semiotics, which became the foundation of ‘reading’ photographs. ~ Peter Langmead in Postcards from Zambia.
