When Joseph Priestley discovered oxygen in 1774, he answered age-old questions of why and how things burn. An Englishman by birth, Priestley was deeply involved in politics and religion, as well as science. When his vocal support for the American and French revolutions made remaining in his homeland dangerous, Priestley left England in 1794 and continued his work in America until his death. His library of some 1,600 volumes and his chemical laboratory, where he first isolated carbon monoxide, were probably the best in the country at that time.

Late in life, the renowned structural engineer Gustave Eiffel (1832-1923) embarked on aeronautical research. Reliable data and repeatable research methods were rare in the early 1900s, but Eiffel brought an engineer's discipline to the field. In the process, he produced the most accurate aeronautical data of the time, confirmed a long-held theory about fluid flow that had never been unequivocally proven, and established a laboratory that became a model for future practice.
