He was a pioneer and pathfinder in the transitional period to a century of specialized research. No other single person illuminated and represented unknown territories more extensively than he.

The discipline of geography, at least in Germany, has so far only concerned itself with his popularized reports. The consistent inclusion of the enormous, still unmined treasures in his scientific work are yet to be incorporated in the regional geography of Asia.
