Researching my novel-in-progress, One Person’s Loss, set during World War Two in New York City, I learned that the first penicillin factory in the world was opened by Charles Pfizer and Company in Brooklyn in 1943. The factory made 90 percent of the antibiotics carried by Allied forces on D-Day. Are you curious about what else was manufactured in New York City to support the war effort? See BEHIND THE STORY.
