Evelyn B. Baldwin, the well-known arctic explorer, was born in Springfield, Missouri, July 2, 1862. He is the son of Elias Briggs Baldwin, who served with distinction during the Civil war. The subject of this sketch was educated at the public schools in Dupage county, Illinois, and, on graduating from the Northwestern college, Naperville, Illinois, taught in district schools for some time. After an experience as professional pedestrian and bicyclist in Europe, he returned to this country and was appointed principal of high schools and superintendent of city schools in Kansas. Next we hear of him as attached to the United States weather bureau and becoming inspector-at-large of the signal corps of the United States army. In 1883 he was a member of the Peary expedition to North Greenland in the capacity of meteorologist. In 1897 he made a voyage to the Andree balloon station in Spitzbergen, hoping to join that ill-fated scientist, but arrived a few days too late. In 1898 he accompanied Wellman’s polar expedition as meteorologist, and secured valuable data in connection with same. He also organized and commanded the Baldwin-Ziegler polar expedition in 1901. He is the author of several works on arctic exploration and is the member of a number of scientific societies. FREDERICK ALBERT COOK. Dr. Frederick A. Cook, physician by profession and explorer by inclination, was born in Callicoon Depot, Sullivan county, New York, on June 10, 1865. He is the son of Dr. Theodore Albert Cook and was first educated in Brooklyn, graduated from the University of the City of New York in 1890, and received his medical degree from that institution in the same year. His work of exploration has been confined to the arctic regions. He was surgeon of the Peary expedition in 1891 and acted in the like capacity for the Belgium antarctic expedition in 1897. Dr. Cook has a fertile pen, and it is mainly through its efforts that he is as well known to the American people as he is. He has contributed liberally to the leading magazines, writing on the problems of the north and south poles; is the author of a monograph on the Patagonians, and has published a work entitled The First Antarctic Night. He is a member of a number of scientific societies, has been decorated by King Leopold of Belgium and has received medals from foreign geological societies as a recognition of his services in the lines indicated.
