Robert H. Goddard: "The Dream That Wouldn't Down" 1965 NASA

'The dream of Dr. Robert Goddard, the father of rocketry, is explored and examined through reminiscences of Mrs. Esther Goddard. Included in the film are historic scenes of Dr. Goddard's early experiments and the personal commentary of Mrs. Goddard.'
Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

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. Dr. Goddard successfully launched his rocket on March 16, 1926, ushering in an era of space flight and innovation. He and his team launched 34 rockets between 1926 and 1941, achieving altitudes as high as 2.6 km (1.6 mi) and speeds as fast 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. 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. 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.
Although his work in the field was revolutionary, Goddard received little public support, moral and monetary, for his research and development work. The press and other scientists ridiculed his theories of spaceflight. And he was not a well man (tubercular). As a result, he became protective of his privacy and his work. Years after his death, at the dawn of the Space Age, he came to be recognized as one of the founding fathers of modern rocketry, along with Robert Esnault-Pelterie, Konstantin Tsiolkovsky, and Hermann Oberth. He not only recognized the potential of rockets for atmospheric research, ballistic missiles and space travel but was the first to scientifically study, design and construct the rockets needed to implement those ideas. NASA's Goddard Space Flight Center was named in Goddard's honor in 1959. He was also inducted into the International Aerospace Hall of Fame in 1966, and the International Space Hall of Fame in 1976...
In late 1919, the Smithsonian published Goddard's groundbreaking work, A Method of Reaching Extreme Altitudes. The report describes Goddard's mathematical theories of rocket flight, his experiments with solid-fuel rockets, and the possibilities he saw of exploring Earth's atmosphere and beyond. Along with Konstantin Tsiolkovsky's earlier work, The Exploration of Cosmic Space by Means of Reaction Devices, which was not widely disseminated outside Russia, Goddard's book is regarded as one of the pioneering works of the science of rocketry, and 1750 copies were distributed worldwide.
Goddard described extensive experiments with solid-fuel rocket engines burning high-grade nitrocellulose smokeless powder. A critical breakthrough was the use of the steam turbine nozzle invented by the Swedish inventor Gustaf de Laval. The de Laval nozzle allows the most efficient (isentropic) conversion of the energy of hot gases into forward motion. By means of this nozzle, Goddard increased the efficiency of his rocket engines from two percent to 64 percent and obtained supersonic exhaust velocities of over Mach 7.
Though most of this work dealt with the theoretical and experimental relations between propellant, rocket mass, thrust, and velocity, a final section, entitled "Calculation of minimum mass required to raise one pound to an 'infinite' altitude," discussed the possible uses of rockets, not only to reach the upper atmosphere but to escape from Earth's gravitation altogether. He determined that a rocket with an effective exhaust velocity (see specific impulse) of 7000 feet per second and an initial weight of 602 pounds would be able to send a one-pound payload to an infinite height...
