His funding included the expedition by Stanley to Africa, in search of Dr. David Livingstone, and an ill fated attempt to explore the North Pole and Arctic region by G.W. De Long in the years between 1879 and 1881.
The 'Jeanette' expedition, as the Arctic trip was known, failed miserably and led to the subsequent death, via starvation, of De Long and 19 fellow crew members. There are several islands in Siberia that bear Bennett's name.
