life

Grote Reber was born in DuPage County, Illinois, Wheaton (near Chicago). He graduated from the Armor Institute of Technology (later the Illinois Institute of Technology) in 1933, and received a degree in radio engineering. Grote Reber later became an amateur radio correspondent, and from 1933 and 1947 worked at many radio manufacturing company. He learned that in 1933 Karl Jansky's study, and decided to enter the field to study, and then tried to enter the Bell Labs where Jansky. However, when faced with just the peak of the Great Depression, so they can not get jobs.

So Grote Reber decided to build a private radio telescope in Wheaton backyard, its design is considered more advanced than Jansky's design, including 9-meter parabolic metal mirror, the radio signals gathered on the receiver mirror 8 meters distance. Reber Radio Telescope was completed later in 1937.

Grote Reber first use 3300 MHz frequencies to experiment, but did not receive any signals from outer space. Later, he successfully used 160 MHz confirmed the discovery Jansky in 1938. He completed surveys map the radio frequency in 1941, and open his important research results, and in between World War II became one of the pioneers of radio astronomy.

Later, he sold the radio telescope US National Institute of Standards and Technology (National Institute of Standards and Technology), the US National Radio Astronomy Observatory by Virginia Green Bank used. Grote Reber is also reconstruction of Jansky's original radio telescope. Grote Reber again actively study of radio astronomy in the 1950s, but at that time there have been many advanced research equipment occurs. Compared to the time he first entered this area has a huge change. Because the frequencies below 30 MHz signal is reflected by the Earth's ionosphere, so he decided to move to Australia, Tasmania, because here was severely affected solar radiation, better research environment. Here he built a new radio telescope in the Southern Hemisphere and radio sky survey in 1960, with this radio telescope.

he does not believe the big bang theory, because he believed red displacement celestial repeated absorption and re-emits the light signal interference or low density material resulting dark. Grote Reber also published an article "Endless, Boundless, Stable Universe" to illustrate his idea of a stable universe.

He died in 2002 in Tasmania Hobart, just two days before the 91-year-old birthday. He was later buried in Tasmania Powell Cemetery, the monument also dispersed in many other radio observatory in the world.
