Signed autograph manuscript drawing of the Apollo 11 Moon landing mission. [Cincinnati], n.d.
ICONIC DRAWING OF AN EPOCHAL MOMENT IN HISTORY.

Typed letter signed to Sam Moskowitz. Princeton: Institute for Advanced Study, April 4, 1951
In this fascinating letter Einstein writes that “According to the special theory of relativity the velocity of light relatively to an inertial system is something clearly defined and this speed of light is a limit for the speed of any object.”

John Jacob Astor, founder of the Astor business dynasty, was the first American multimillionaire. In his time he was “the richest and most powerful of American businessmen.

GODDARD, ROBERT H
Autograph manuscript diagrams and text. [n.p., n.d.],
Goddard (1882-1945), the “father of modern rocket propulsion,” launched the world’s first liquid-propellant rocket on March 16, 1926, at Auburn, Massachusetts, a “feat as epochal in history as that of the Wright brothers at Kitty Hawk” (NASA). Goddard had a rare genius for invention and these notes suggest the endless refinement necessary to create a dependable, operational rocket engine.
VON BRAUN, WERNHER
Original drawing, “3-Stage Satellite Vehicle (pitch plane)” signed and dated 1952. [Huntsville, Alabama, 1952.]
This is an original signed drawing of a space ship by Wernher von Braun, the father of the American space program. He made this drawing for his landmark Colliers series “Man Will Conquer Space Soon” (1952-54), which played a central role in inspiring a generation of rocket scientists and convincing the public of the possibility of space exploration. These essays covered seemingly every aspect of manned space flight and anticipated many developments including the enormous multi-stage vertical launch vehicle (to become Saturn V), a horizontal landing space ferry (the Space Shuttle), an orbiting space station, a lunar landing, the establishment of a base on the moon, and ultimately a manned expedition to Mars.
