Penicillin Sir Alexander Fleming's 1928 discovery of penicillin in bread mold was a tremendous breakthrough for medical science. Unfortunately, Fleming's process for harvesting the antibiotic took months to generate a small amount. During World War II, as demand for penicillin rose, researchers worked feverishly to synthesize the penicillin molecule. More than a thousand scientists in 39 U.S. labs became involved in the project. But when the war ended and the molecule still had not revealed its structure, the funds for research ended. From 1948 to 1957 only one laboratory of continued the research-John Sheehan's. In March of 1957, while a professor at the . . . .

Helicopter Igor I. Sikorsky designed the world's first successful multimotor airplane and the world's first true production helicopter. From 1925 to 1940 he created a series of increasingly successful aircraft which gained for America numerous world records for speed, range and payload. The famed Sikorsky flying 'Clippers' helped pioneer trans-Atlantic and trans-Pacific commercial passenger services. Despite the success of the flying boats, Sikorsky continued studying the helicopter. His U.S. Patent 1,994,488, filed June 27, 1931, marked the crucial breakthrough.
