Charles George Alexander Winnecke (18 November 1857 – 10 September 1902)[1] was an Australian explorer and botanist best known for leading the Horn Expedition to Central Australia in 1894.

[3][4] A decade later, he led the Horn Expedition to Central Australia from May to August 1894, a scientific exploration of the region's geology, zoology, botany and Indigenous people.

It resulted in the publication of the Report on the work of the Horn Scientific Expedition to Central Australia in four volumes from 1896 to 1897.

The objects were subsequently interpreted with the assistance of another guide, the sometime police tracker and Aboriginal resistance identity Arrarbi.

When removing the objects he left 'a number of tomahawks, large knives and other things in their place, sufficient commercially to make the transaction an equitable exchange'.
