Note 9 — Chapter III · DEVELOPMENT OF THE CHEMICAL WARFARE SERVICE

Underhill, in charge of Therapeutic Research; Major M. C. Winternitz, in c of Pathological Research and Captain E. K. Marshall in charge of Pharmacological Research. About May 1, 1918, Pharmacological Research became so extensive that the Section was made into two, with Marshall and Loevenhart in charge, while Dr. Hunt was appointed special adviser on pharmacological problems. When the transfer to the War Department was made, Henderson, Underhill, Winternitz and Marshall were transferred to the Medical Division.
