UNDAUNTED: THE FORGOTTEN GIANTS OF THE ALLEGHENY OBSERVATORY tells the true but largely forgotten story of the scientific pioneers behind early aviation and the founding of astrophysics. Samuel Pierpont Langley, John and Phoebe Brashear, and James Keeler embarked on studies of the sun and skies in the 19th century, an era when many dismissed astronomy as "junk science." They endured years of enormous hardships, demoralizing setbacks and humiliating failures to ultimately make world-changing contributions to science and technology. UNDAUNTED features interviews with scientists, academics, historians and observatory archivists, including astrophysicist Dr. Neil deGrasse Tyson of the American Museum of Natural History.
