Discorsi e Dimostrazioni Matematiche, Intorno a Due Nuoue Scienze attenenti alla mecanica & movimenti locali …. Leiden: Elzevir, 1638
First edition, the rare first issue, of the Two New Sciences, Galileo’s greatest work. Galileo’s “Mathematical Discourses and Demonstrations … is now considered by most scientists as Galileo’s greatest work. … It was upon his foundations that Huygens, Newton and others were able to erect the frame of the science of dynamics, and to extend its range (with the concept of universal gravitation) to the heavenly bodies” (PMM).
Euclid’s Elements “has exercised an influence upon the human mind greater than any other work except the Bible”EUCLID
Elementa Geometriae [translated by Adelard of Bath, edited by Campanus of Novara].. Venice: Erhard Ratdolt, 1482
First edition of the most important book in the history of mathematics. Euclid’s Elements is “the oldest mathematical textbook still in common use today” and “a model for subsequent mathematical books” (PMM). The book’s use of hundreds of complex geometrical diagrams makes this an “outstandingly fine piece of printing” (PMM), a landmark from the dawn of printing.

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.]
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.
