Please refer to the Wikipedia entry to learn about John Hanning Speke.
Speke accidentally shot himself, ending his life very early.
The first edition shown at left is Speke's most famous book, published in 1863.
I own a copy just like the one shown at left, except that my copy is not as nice. I also own a copy of the first American edition, which was published in 1864, a year after the first British edition.
Speke also wrote WHAT LED TO THE DISCOVERY OF THE SOURCE OF THE NILE, but I do not own a copy.
