Roger Casement (1864–1916) is best remembered as one of Ireland's most significant historical figures, but before his execution for his role in the 1916 Easter Rising, he earned an international reputation as a humanitarian and diplomat. Serving as a British consul in Africa and South America, Casement exposed the brutal exploitation and abuse of indigenous peoples in the Congo Free State and the Peruvian Amazon. His reports helped bring global attention to these atrocities and established him as one of the leading human rights campaigners of his time.



What is less well-known to the general public is that Casement also had a lifelong fascination with the natural world. During his extensive travels, he took every opportunity to observe and collect plants and animals, carefully documenting the wildlife he encountered in some of the world's most remote regions.

In celebration of this aspect of Roger Casement’s life, and to commemorate the 110th anniversary of his execution, on Bank Holiday Monday 3rd August, as part of our Nature on One series, we broadcast a special documentary, presented by Eric Dempsey, about Casement’s life as a naturalist. In case you missed it, we will be repeating this programme next Monday, August 24th , in our regular Mooney Goes Wild slot at 22:00 on RTÉ Radio One.
