JANEWAY, THEODORE CALDWELL

(Nov. 2, i872-Dec. 27, 1917), physician, the
son of Edward Gamaliel Janeway [q.v.'] and
Frances Strong- Rogers, was born in New York
City. After leaving the Cutler School the son
entered the Sheffield Scientific School of Yale
College, taking the special premedical course.
Having received the degree of B.Ph. from Yale
in 1892, he at once began the study of medicine
at the College of Physicians and Surgeons in
New York City and after receiving his medical
degree in 1895 he entered his father's office in
preference to taking the usual post-graduate
study abroad. Here he received an intimate
training and always remained in perfect accord
with his father. At this period (1895-96) he
served as instructor in bacteriology at his alma
mater. In 1898 he was appointed an instructor
and later lecturer on medical diagnosis at Belle-
vue Hospital Medical College which about this
time merged with the medical department of
New York University and became the Univer-
sity and Bellevue Hospital Medical College. He
resigned in 1907 to become associate professor
of clinical medicine at the College of Physicians
and Surgeons and two years later he succeeded
Walter B. James as Bard Professor of Medicine.
His first hospital appointment was at the City
Hospital, Welfare Island, the status of which
was at the time very low. With Horst Oertel he
reorganized the staff and also introduced the
clinico-pathological conference, an innovation
which was widely copied. He became interested
in the problem of the worker incapacitated by
disease or accident and was active in the work
of the Charity Organization Society. He was
for years visiting physician to the Presbyterian
and St. Luke's hospitals and much of the credit
for the merger of the former with the College
of Physicians and Surgeons is assigned to him,
this consolidation forming the nucleus for the
medical center on Washington Heights in New
York City. In 1907 he was made secretary of
the Russell Sage Pathological Institute and in
1911, following the death of Christian Archi-
bald Herter [g,v.], he was made one of the sci-
entific directors of the Rockefeller Institute for
Medical Research. During his career in New
York he wrote little, but a work on the blood
pressure published in 1904 calls attention to the
fact that he was perhaps the first American phy-
sician to make routine use of this resource in
the clinic, while he is also credited with the in-
troduction of the first practicable apparatus for
this purpose.

Janin

In 1914 Janeway was called to Johns Hopkins
Hospital and School of Medicine to become the
first of the full-time professors of medicine un-
der the Welch Endowment Fund. At the same
time he was placed at the head of the hospital.
As the income from such positions was far short
of what he might have earned as a private prac-
titioner he was allowed to do a certain amount
of consultation work and is reputed to have
charged very high fees. He took part in estab-
lishing the post-graduate school for the study of
tuberculosis at Saranac Lake and was for three
years president of the Laennec Society of Johns
Hopkins Hospital for the study of tuberculosis.
When the United States entered the World War
he promptly volunteered his services and at the
request of General Gorgas, then surgeon-gen-
eral of the army, he took charge of the section
of cardio-vascular diseases of the Division of
Internal Medicine, with the rank of major of
the United States Reserve Corps. This work in
addition to his regular duties threw a heavy
burden of labor upon him and is believed to have
been indirectly responsible for his premature
death. His military duties included the plan-
ning of special hospitals both at home and over-
seas, the selection of internes and assistants for
medical service in hospitals and cantonments,
the selection of a corps of experts in the diag-
nosis of cardiac diseases, and the inspection of
camps and cantonments. He worked in collab-
oration with Maj. W. T. Longcope who was to
become his successor. His death took place af-
ter a week's illness with pneumonia. In addi-
tion to his book, The Clinical Study of Blood
Pressure (1904), he wrote an unpublished vol-
ume on diseases of the heart and bloodvessels.
He was survived by his wife, Eleanor C. Alder-
son, and five children.

JANIN, LOUIS (Nov. 7, i837-Mar. 6, 1914),
mining engineer, was a notable influence in the
development of western metal mining. He was
born in New Orleans, the son of Louis and Juliet
(Covington) Janin. His grandfather had been
an officer in the French army. The father came
to America in 1833 and became a successful
lawyer in New Orleans. Young Louis was the
oldest of six sons, of whom three became mining
engineers, perhaps because of their father's con-
nection with litigation over the New Almaden
quicksilver mines in California. The two oldest
sons, Louis and Henry, after several terms at
