Max Demarest: Encyclopedia Arctica 15: Biographies

Max (Harrison) Demarest (1910-1942). Scientist and Greenland Explorer. Specialist in structure of glacial ice.

Max Demarest was born at Flint, Michigan, February 18, 1910, the son of Harry and Mabel Slayton Demarest. His father was official stenographer of the Seventh Judicial Circuit Court at Michigan. Max, after graduation from the Flint Junior College, entered the University of Michigan in 1929, where he specialized in geology. He was graduated from that University in 1934 with the degree of Bachelor of Arts. While still an undergraduate he was appointed an assistant in the Geological Department of the University. In the year 1930-1931 (summer to summer) he went to Greenland as meteorolo– gist of the Northern Party of the Third University of Michigan Greenland Expedition, which was led by William S. Carlson. This party was based at Angparlartok near Upernivik in about latitude 73° N. Their experiences there have been described in a book by the leader ( Greenland Lies North , New York, Macmillan, p. 306, illus., 1940). Demarest was next in Greenland in 1932-33 as meteorologist of the University of Michigan-Pan American Airways Expedition under the leadership of Dr. Ralph L. Belknap. The base (Peary Lodge) was on the Upper Nugsuak Peninsula of Northwest Greenland. In both this and the earlier expedition Demarest had charge of the aerological work, daily pilot-baloon ascents for study of the upper air currents. On the

later of these expeditions he was navigator of the sledge party in the difficult journey which accomplished the relief of Belknap from a seven weeks' vigil at Camp Watkins, which was about three hundred miles to the east on the inland ice.

After his graduation in 1934 Demarest took up graduate study in geology at the University of Cincinnati and was given the degree of Master of Science in 1936. In 1934 he had married, at Cincinnati, Rebecca Humphreys. He continued his graduate studies at Princeton University, where he held the position of Assistant Instructor, and where he received the degree of Doctor of Philosophy in 1938. He was then appointed Assistant Professor of Geology at the University of North Dakota. Here he began his studies of the structure of glacial ice and the nature of its motion, studies which with interruptions he continued until his death in 1942.

On a Guggonheim Fellowship this research was vigorously pursued at Yale University as Sterling Fellow of the University and National Research Fellow in geology. After two years of research at Yale University, Demarest was called to Wesleyan University at Middletown, Ct., as Acting Chairman of the Department of Geology.

In 1942 Demarest was commissioned First Lieutenant in the United States Air Force, and by air transport he left for Greenland in July on a secret mission. In the following December news of his death in Greenland was given out by the War Department. It was later to be learned that he had been killed, together with Staff Sergeant Don T. Tetley, when, in an attempt to rescue the crew of a Flying Fortress which had crashed on the inland ice of East Greenland, their motor sled had broken through the snow bridge over a crevasse, precipitating them to the bottom far below. When, much later, a rescue party had reached the scene of the accident, the tail

of the wrecked tractor could be seen, but the bodies of the two officers were never recovered. Demarest left a widow and a five-year old daughter. Mrs. Demarest had been able to assist her husband in his research on ice.

Demarest was regarded as one of the outstanding scientists in his field of glacial research. He was a Fellow of the Geological Society of America, member of the American Geophysical Union, the International Committee on Snow, and the Explorer's Club. His portrait, painted by Mrs. Patricia H. Stratton, hangs in the Geological Department of the University of Michigan.
