first edition. 'American celestial mechanician Wallace Eckert pioneered the application of punch-card computing machines to problems of astronomical orbit determinations . . . In the late 1950s and early 1960s, Eckert worked on developing precise positions of the Moon based on the formulas developed by the astronomer and mathematician Ernest Brown . . . Without the pioneering computer work done by Eckert, his staff, and students in determining the exact position of the Moon at any given time, the manned landings on the Moon might not have been possible by the end of the 1960s'—BEA, pages 323-24.
