Dr. Frederick A. Cook, of Brooklyn--physician, anthropologist, Arctic and Antarctic explorer, author and lecturer--has not only made an enviable reputation for himself along each of these varied lines, but is personally one of the most charming of men. He is as modest and unassuming as he is accomplished, although he has succeeded in doing some things which no other man before him ever did. From nearly 80 degrees north latitude to 71 degrees 36 minutes south latitude is a long distance for a north-and-south journey, but Dr. Cook can say, as no other man living can: “I have done it.” [Illustration] He filled the position of surgeon and anthropologist with Peary’s first Arctic expedition in 1891, and during 1893 and 1894 he was engaged in explorations of the west coast of Greenland. Again in 1897 he joined the Belgian expedition which sailed on the _Belgica_ to explore the Antarctic continent and channels, being the only American in the party. For thirteen months their ship drifted in the pack ice, in which she had been caught, and was finally got out only by sawing a channel through the ice nine miles long. This expedition was the first, and Dr. Cook was the only American, that ever camped and sledged on the Antarctic continent. While in these far southern latitudes, Dr. Cook, as anthropologist to the expedition, visited and described a cannibal tribe from whom no previous scientist had escaped alive. His lecture descriptive of his adventures has proven one of the most interesting yet offered to the lyceum. It is illustrated with photographs taken by the doctor himself, and these are as beautiful as they are unlike any others ever shown to the public. Dr. Cook is gifted with a fascination of description and a powerful voice which make his lecture even more interesting, if possible, than to read of his thrilling adventures in his book, recently published. Among polar explorers I do not regard any one as more bold, more to be depended upon for accuracy of statement, or whose scientific training better fits him rightly to appreciate the value of each new fact discovered, than Dr. Frederick A. Cook, our fellow-countryman.
