National Geographic : 1957 Oct
p~ NO WONDER the natural science articles of Dr. Paul A. Zahl, distinguished biologist and physiologist, are so popular with all members of the 2,175,000 National Geographic families. All members of his family share his adventures in the world of nature. When Dr. Zahl explores a tidal pool, a cathedral lighted rain forest, or a wild-flower-strewn mountain top, it's a family affair. Mrs. Zahl and her eight-year old namesake Eda, as well as young Paul, shown here with his scientist-writer-photographer father, accom pany him on most of his world-ranging expeditions. Their questions give him plenty of practice in ex plaining nature's wonders in easily understood terms. Dr. Zahl's warm, human, and brilliantly illustrated articles are eloquent of their author's extraordinary range of interest and knowledge. His subjects have ranged from the Gulf Stream to the tides of Fundy, from the "wilds" of his pet-filled city parlor to Olym pic National Park, and from the scarlet ibis of Vene zuela to the honey-eating lorikeet of Australia. Versatile Dr. Zahl has just made for The Magazine a color record of dwarf sea horses in Florida waters. Now, with a National Geographic grant, he is off to the Amazon in quest of giant ants. Thus Dr. Zahl and other talented members of the National Geographic family contribute to knowledge of natural history in the best traditions of such predeces sors as George Shiras 3d, whose 1906 flashlight pic tures of wild animals in their natural habitat were the first ever published.
