The inspiring story of the man who doggedly sought the secrets hidden within dinosaur eggs. From Siberian Prisoner to Dinosaur Egg Detective explores the fascinating story of Karl Franz Hirsch (1921–1996). After serving in the German army in WWII, being wounded and captured by the Soviets in Danzig and then sent to a prisoner of war camp in Siberia, Hirsch went on to become one of the world's leading experts on fossil eggs. After starting a new life in Colorado, Hirsch became an avid fossil hunter and one day discovered by accident a dinosaur egg. Armed with curiosity and a microscope, he began to study it. In 1979, at the age of 58, Hirsch published his first scientific paper on fossil eggs. Hirsch went on to write dozens of influential technical papers and collaborate with professional paleontologists at the University of Colorado Boulder and elsewhere. At his death, his immense research collection consisted of 35,000 photographs, 20,000 pages of notes, and 3000 fossil egg specimens.
