Robert Hutchings Goddard (October 5, 1882 – August 10, 1945)
was an American engineer, professor, physicist, and inventor who is credited
with creating and building the world's first liquid-fueled rocket, which
he successfully launched on March 16, 1926. Goddard and his team launched 34
rockets between 1926 and 1941, achieving altitudes as high as 2.6 km (1.6
mi) and speeds as high as 885 km/h (550 mph).
Goddard's work as both theorist and engineer anticipated
many of the developments that were to make spaceflight possible.[4] He has been
called the man who ushered in the Space Age. Two of Goddard's 214
patented inventions — a multi-stage rocket (1914), and a liquid-fuel rocket
(1914) — were important milestones toward spaceflight.[6] His 1919 monograph A
Method of Reaching Extreme Altitudes is considered one of the classic texts of
20th-century rocket science. Goddard successfully applied three-axis
control, gyroscopes and steerable thrust to rockets, to effectively control
their flight.
