The volume dedicated to Albert Einstein, is the only book written by Dr. Frank Back, "The Father of the Zoom Lens" and creator of the first widely used zoom lenses for film and television. Dr. Back a close friend of Albert Einstein was persuaded by Einstein to take the trip commemorated in this beautifully produced volume in order to capture the total eclipse of the sun, which occurred on June 20, 1955. Dr. Back intended to provide conclusive evidence for Einstein's theory of relativity by calculating the optical distortion, if any, of starlight caused by the sun's gravity. In 1919, Einstein's general relativity principles were supported by observations of a solar eclipse. The two scientists conferred on the project for over a year. Armed with a special Zoomar designed and built, wide-angle, solar-eclipse, spectrograph, Dr. Back was off to the Philippine Islands to board a military jet and chase the eclipse. Einstein however died while Back was on his way to Manila. Unable to report the excursion to his friend, Dr. Back dedicated this book to his memory. In a TBCL dark green cloth slipcase. Size: 8vo - over 7¾" - 9¾" tall.
