“Can you tell me anything about the Physicians Drug Syndicate.... They are pushing the sale of Thymozene and offering One Hundred Dollars’ worth of stock fully paid and non-assessable, free to those sending in their order, and also a copy of Dr. Loffler’s Lectures on the Blood.”
And from another physician:
“What do you know of Charles Loffler, M.D., and his Intravenous Compound? A few evenings ago a man who appeared to be about 40 years old came to my office and tried to interest me in the above-mentioned article; he claimed to be Dr. Charles Loffler of Chicago. With him was a young lady whom he introduced as Miss B——. Miss B—— said that she had been with Dr. X—— And this also: “Charles Loffler, M.D., or his agent was traveling around inducing one M.D. in each town to take up his methods of blood examination and treatment and with a little advertising of blood examinations free the doctor selected gets quite a run of patronage.” Another physician writes: “My attention has been called by another physician to Loffler’s Intra-Venous Compound. May I trouble you to give me any information that you may have with regard to its composition and its value as a therapeutic agent?” C. L. Loffler does business from Rooms 1101–1102, Venetian Bldg., Chicago, the location of the “Intravenous Chemical Co.,” the “Physicians Drug Syndicate” and the “Ma-Oze Chemical Co.” Of these, more later. The Journal has in its files a large amount of material regarding Loffler. A brief résumé of that part of the material dealing with Loffler’s professional activities will be given for the purpose of allowing physicians to evaluate the scientific status of Loffler’s “Lectures,” “Post-Graduate Courses,” his therapeutic “discoveries” and his products. It seems that Loffler was reared in Yankton, S. D. In 1898–1899, Loffler was a senior student at John Creighton Medical College, but, for reasons that need not be gone into here, he was never graduated. He received a diploma from Barnes Medical College in 1900, and in the same year was licensed to practice in South Dakota. In 1902 he was at Le Mars, Iowa; in 1904 his name appears in the medical directory, under Sioux Falls, S. D., as “Specialist in Chronic Troubles.”
