In the Name of Medicine (Jesse Lazear, Alexander Bogdonov, Michael Servetus)

Long Forgotten Tracks (Percy Fawcett, O.C. Marsh, Edward Drinker Cope, Vavilov)

Nature is powerful and can snuff out life in an instant, but for three intrepid adventurers, nature holds mysteries just waiting to be discovered.

Against Nature (Tim Samaras, David A. Johnston, George Mallory)

Breaking the glass ceiling is never easy, but for some female inventors, science comes at an added price.

Female Inventors (Marie Curie, Dian Fossey, Elizabeth Fleischmann)

People who defy earthly forces and dream of high-flying adventures.
