VON BRAUN, WERNHER
Original drawing, “3-Stage Satellite Vehicle (pitch plane)” signed and dated 1952. [Huntsville, Alabama, 1952.]
his 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.
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.

Autograph Letter Signed [to Henry Denny]. Down, Kent, June 1, 
VERY EARLY DARWIN INVESTIGATION OF THE RACES OF MAN. In 1834 Darwin heard that head lice vary among the races of man while on the voyage of the Beagle. In his Beagle zoological diary he wrote, “Mr Martial, a surgeon of an English Whaler assures me that the Lice of the Sandwich Islanders … if they strayed to the bodies of the English in 3 or 4 days died … If these facts were verified their interest would be great.— Man springing from one stock according his varieties having different species of parasites.— It leads one into many reflections.” Intrigued by the implications of this observation, Darwin began collecting specimens for further research.
