The author was born Nov. 30, 1897 at West Haverstraw, N. Y. Aftet
graduating from Haverstraw High School in 1915, he studied chemical
engineering for three years at Rensselaer Polytechnic Institute, where he held
New York State and Institute Scholarships. He was the 1918 winner of
the Laflin Prize. In the fall of 1918 he enrolled in the Chemical 'Warfare
Division of the Students' Army Training Corps at Cornell University, ex-
pecting to specialize in organic chemistry, a plan which was frustrated by
the armistice.

In 1919, a year devoted to teaching, a personal experience led him to
enter the field of chiropractic. He was graduated in 1921 from the Palmer
School of Chiropractic with the degree of D.C. After a sojourn in Mexico,
he accepted a post on the faculty of the Texas Chiropractic College at San
Antonio, Texas, but in 1925 he returned to Mexico to enter private practice
at Zamora, in the state of Michoacan. At the height of the church-state
controversy, when Mexico was undergoing a severe economic crisis, he came
to New York to practice and joined the faculty of the Eastern Chiropractic
Institute, where, since 1928, he has been professor of physiology and bio-
chemistry.

The Mexican experiences having aroused a keen interest in Mexico's
Indian background, he began, in 1934, to devote his spare time to the
formal study of anthropology at Columbia University. In 1935 he made a
brief ethnological field trip to the Tarascan area. In 1937 he was the first
student to take the B.S. degree at Columbia offering anthropology as major.
Continuing as a graduate student, he received archaeological field training
on the 1938 Columbia University-North Dakota State Historical Society
Expedition, worked for a time under Dr. Alfonso Caso in Mexico, and finally
received the appointment to assist Dr. M. W. Stirling at Tres Zapotes, thus
initiating the work which culminated in the present report.

He is at present a lecturer in anthropology at Hunter College in the
City of New York and serves the National Chiropractic Association as
Director of Research. In the latter capacity he is cooperating with the
Baruch Committee on Physical Medicine.

He is founder and first editor of Science Sidelights, author of The Chal-
lenge of Human Engineering (a pamphlet), co-author (with Dr. J. R. Verner
) of Rational Bacteriology, and a contributor to Boy's World, Mex-
ican Magazine, Mexican Life, Pan-American Traveler, American Anthropol-
ogist, Journal of American Folklore, National Chiropractic Journal, Journal
of the New York State Chiropractic Society, etc.
