Duke Announces Dive Ends Today
Six Promotions
Five Duke physicians have been
promoted to full professor and one to
associate professor.
The new professors, all in the
Department of Psychiatry, are Drs.
Everett Ellinwood Jr., Robert L. Green
Jr., Eric A. Pfeiffer, John B. Reckless and
William W. Zung.
Dr. Charles B. Hammond was
promoted to associate professor of
obstetrics and gynecology.
Ellinwood received his B.S. and M.D.
degrees from the University of North
Carolina at Chapel Hill. He served his
residency in psychiatry at North Carolina
Memorial Hospital in Chapel Hill and
came to Duke in 1965 as a research
fellow in psychiatry.
Prior to his arrival at Duke, he was
chief of the Female Addiction Service at
the United States Public Health Service
Hospital in Lexington, Ky., and a
consultant at the Mental Health Clinic in
Frankfort, Ky. At Duke Ellinwood also
holds an appointment as assistant
professor of pharmacology.
Green, of Fairfield, Ala., came to
Duke in 1958 as an assistant in
psychiatry. He obtained his B.S. degree
from the University of Alabama in
Birmingham and M.D. degree from
Hahnemann Medical College in
Philadelphia, Pa., in 1946.
After having a private practice in
Birmingham, he worked at the Veterans
Administration Kennedy Hospital in
Memphis, Tenn., and the Veterans
Administration Hospital in Durham
where he presently holds the position of
chief of psychiatry.
A native of Rauental, Germany,
Pfeiffer received his A.B. and M.D.
degrees from Washington University in St.
Louis, Mo. He served his internship in
internal medicine at the Bronx Municipal

Welcome Back Up, Boys!
Six men who have been on a long trip,
but have never moved more than a few
feet, are due back today.
They are the six divers who, since
Thursday morning, Jan. 10, have been
locked in Duke's hyperbaric chamber for
a series of deep-pressure dives and tests
that may provide some more answers to
how man can function in the deep sea.
I The project is called "Deep Work 1000."
According to the timetable of the dive,
the men are scheduled to walk out of the
chamber sometime this afternoon.
There will be eight coming out
whereas only six went in initially. That's
KEEPING IT ALL TOGETHER-Dr. L.
Sigfred Linderoth Jr., professor of
mechanical engineering at Duke, checks
some readings from hyperbaric chamber
tests during "Deep Work 1000," which is
scheduled to end today. Linderoth has
served as coordinator and manager of the
dive. Behind him is Dr. Howard Rothman
of the University of Florida. (Photo by

because two other people—Dr. Douglas
Blenkarn, of Duke's departments of
anesthesiology and physiology-pharma-
cology, and Technician "Butch"
Doar—locked into the chamber with the
divers last Sunday to do a series of blood
gas analyses on the divers.
The six divers are Robert J. (Dutch)
Ritter of St. John's, Newfoundland;
Charles H. (Chuck) Meyer Jr. and Richard
C. (Chris) Tietze of Ft. Pierce, Fla.; Navy
LCDR John T. Atwell of Vero Beach,
Fla.; and Pete Maddison and Geoffrey
Baker from England.
Ritter, Maddison and Baker work for
Oceaneering International, Inc., of
Houston, Tex.; Meyer and Tietze and
with the Smithsonian Institution; and
Atwell is with the National Oceanic and
Atmospheric Administration.
In addition to those organizations and
Duke, other sponsors of the dive are the
University of Florida Communication
Sciences Laboratory, Harbor Branch
Foundation and the Naval Medical
Research Institute.
Early in their dive, the men were taken
to pressures equivalent to 870 feet
beneath the sea. From that level, they
made what are called "excursion dives"
of two hours each to the maximum
pressure depth of the chamber, 1,000
feet.
The pressure experienced at 1,000 feet
under the sea is 446 pounds per square
inch of the body's surface.
One tall tale that was told around the
medical center last week related how the
pressure in the chamber squeezed the
divers' bodies into a fraction of their
normal size.
This, of course, is not true. The human
body very quickly becomes equalized to
deep-sea pressures, meaning that, in
