Volkmar Kurt Wentzel (February 8, 1915 – May 10, 2006) was a German American photographer and cinematographer.
He worked for nearly 50 years for the National Geographic Society as a darkroom technician and photographer, and his professional and personal work was highly acclaimed.
He was one of the first people to take photographs of then-little known country of Nepal, and was noted for documenting the final years of many of the traditional tribal kingdoms of Africa.
