ET and was
Electrothermal AAS ( ET AAS ) using graphite tube atomizers was pioneered by Boris V. L ’ vov at the Saint Petersburg Polytechnical Institute, Russia, since the late 1950s, and further investigated by Hans Massmann at the Institute of Spectrochemistry and Applied Spectroscopy ( ISAS ) in Dortmund, Germany.
ET, in turn, can now be seen ( in light of modern results ) as close to the average mean solar time between 1750 and 1890 ( centered on 1820 ), because that was the period during which the observations on which Newcomb's tables were based were performed.
An impression has sometimes arisen that ephemeris time was in use from 1900: this probably arose because ET, though proposed and adopted in the period 1948 1952, was defined in detail using formulae that made retrospective use of the epoch date of 1900 January 0 and of Newcomb's Tables of the Sun.
Ephemeris time ( ET ), adopted as standard in 1952, was originally designed as an approach to a uniform time scale, to be freed from the effects of irregularity in the rotation of the earth, " for the convenience of astronomers and other scientists ", for example for use in ephemerides of the Sun ( as observed from the Earth ), the Moon, and the planets.

TT shares the original purpose for which ET was designed, to be free of the irregularities of mean solar time.
It was designed for continuity with ET, and it runs at the rate of the SI second, which was itself derived from a calibration using the second of ET ( see, under Ephemeris time, Redefinition of the second and Implementations.

* Ephemeris Time ( ET ) was from 1952 to 1976 an official time scale standard of the International Astronomical Union ; it was a dynamical time scale based on the orbital motion of the Earth around the Sun, from which the ephemeris second was derived as a defined fraction of the tropical year.
For the calculation of ephemerides, TDB was officially recommended to replace ET, but deficiencies were found in the definition of TDB ( though not affecting T < sub > eph </ sub >), and these led to the IAU defining and recommending further time scales, Barycentric Coordinate Time ( TCB ) for use in the solar system as a whole, and Geocentric Coordinate Time ( TCG ) for use in the vicinity of the Earth.
ET, after confirming that Explorer 1 was indeed in orbit, a news conference was held in the Great Hall at the National Academy of Sciences in Washington, DC to announce it to the world.
