1954 American engineer James H. Trexler first transmitted the sound of a human voice beyond the ionosphere and back to Earth after reflecting off the moon. This “Communication Moon Relay” was designed to develop a secure and reliable method of wireless communication by using the Moon as a natural communications satellite.
1950 The first successful rocket launch from Cape Canaveral took place. “Bumper” No. 8 was a captured German V-2 rocket with the payload replaced by another rocket, the 700-pound Army-JPL Wac Corporal.
1847 Richard M. Hoe of New York City patented the rotary type printing press. He created a revolution in printing by rolling a cylinder over stationary plates of inked type and using the cylinder to make an impression on paper. This eliminated the need for making impressions directly from the type plates themselves, which were heavy and difficult to maneuver.
1844 American mechanical engineer Henry Rossiter Worthington patented the independent single direct-acting steam power pump, an invention which laid the foundation of the entire pump industry. This invention solved the major steam-engine problem of supplying water to the boiler – even when the engine was shut down – and replaced hand-pumping to keep the boiler filled.
