known as the Father of Modern Rocketry in
the United States
inspired by H.G. Wells' book, "War of
the Worlds" for developing his rockets
wrote a paper during his college years that
was published by the Smithsonian Institute in 1920 that suggested a liquid-fueled
rocket could be sent to the moon
in 1926, he launched the 1st liquid-fueled
rocket to a height of 41 feet and total flight distance of 184 feet in 2.5
seconds
in 1930, launched the 1st rocket propelled
with liquid nitrogen and with gyroscopic controls that rose to a height of
4800 feet, traveled a total distance of 13000 feet at 550 miles per hour
holds 250 patents in rocketry which are still
producing royalties for his estate

known as the Father of Cosmonautics in Russia
he never actually built rockets but worked
out many of the principles of astronautics and designed many suitable rockets
in the form of drawings
he drew the above picture in 1883, showing
cosmonauts in weightlessness, gyroscopes for altitude control, and an airlock
for exit into free space
he wrote a book in 1929, "The Space
Rocket Trains", about his original idea of a multi-stage rocket which
consisted of several separate rockets, proving that this type of rocket could
attain escape velocity and fly into Earth's orbit

known as the Father of Space Travel
famous for his writings which helped create
rocket societies eventually assisting with the development of the V-2 rockets
used in World War II
by the age of 14, he had already envisioned
a "recoil rocket" that could propel itself through space by expelling
exhause gases
in 1923, he became the first to prove that
rockets could put a man into space
