(1750) Eckert

Reference work entry

1950 NA1. Discovered 1950 July 15 by K. Reinmuth at Heidelberg.

Named in memory of Wallace J. Eckert (1902–1971), Director of the U.S. Nautical Almanac Office from 1940 to 1945 and a pioneer in the use of automatic computing machines. On two occasions he dedicated the most powerful computing machine ever built (SSEC in 1948 and the NORC {see planet  (1625)} in 1954). With Brouwer and Clemence {see planets  (1746) and  (1919)} he produced the integration of the orbits of the five outer planets. By use of sophisticated computing techniques he was able to check and extend Brown’s {see planet  (1643)} lunar theory. He was president of the IAU Commission 7 from 1967 to 1970. (M 3934)
