Wiliam Burchell, 19 June 1811. The white rhino was originally known as "Burchell's rhino". The quagga was known as "Burchell's zebra".

The book - Safari: A Chronicle Of Adventure - records all the early hunters. It was compiled by Bartle Bull, son of Bartle Brennen Bull - a famous White Hunter. Printed in 1988.

I might part with my copy, but it will be expensive (price not established yet.).

Another book is African Hunter II. Boddington & Peter Flack. Printed 2004.
Same story for my copy.
