A warning for Aboriginal and Torres Strait Islander listeners - this programme contains the names and voices of people who have died.

Max Pearson presents a collection of this week’s Witness History episodes from the BBC World Service.

First, the story of Brazil's most wanted, Carlos Lamarca. He was a captain who deserted the army in the 1960s and joined in the armed struggle against the military regime in the country.

Then, Bill Booth - historian of twentieth century Latin America at University College London - joins Max to talk about other revolutionary figures from South America.

Next, the story of Australia's first Aboriginal MP and how he fought for indigenous rights.

Plus, the 90th anniversary of the first ever quintuplets, the 1984 Apple commercial that changed advertising and the 2014 Flint, Michigan water contamination crisis.
