The Emperor of All Maladies: A Biography of Cancer

by Siddhartha Mukherjee

Penicillin, that precious chemical that had to be milked to its last droplet during World War II (in 1939, the drug was reextracted from the urine of patients who had been treated with it to conserve every last molecule), was by the early fifties being produced in thousand-gallon vats. In 1942, when Merck had shipped out its first batch of penicillin—a mere five and a half grams of the drug—that amount had represented half of the entire stock of the antibiotic in America. A decade later, penicillin was being mass-produced so effectively that its price had sunk to four cents for a dose, one-eighth the cost of a half gallon of milk. New antibiotics followed in the footsteps of penicillin: chloramphenicol in 1947, tetracycline in 1948. In the winter of 1949, when yet another miraculous antibiotic, streptomycin, was purified out of a clod of mold from a chicken farmer’s barnyard, Time magazine splashed the phrase “The remedies are in our own backyard,” prominently across its cover. In a brick building on the far corner of Children’s Hospital, in Farber’s own backyard, a microbiologist named John Enders was culturing poliovirus in rolling plastic flasks, the first step that culminated in the development of the Sabin and Salk polio vaccines. New drugs appeared at an astonishing rate: by 1950, more than half the medicines in common medical use had been unknown merely a decade earlier.
