	Wallace J. Eckert - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-25)
		Wallace John Eckert (June 19, 1902 – August 24, 1971) was a statistician and computational specialist at the Thomas J. Watson Astronomical Computing Bureau at Columbia University.
		The Astronomical Computing Bureau was supported by Dr. Thomas J. Watson, President of IBM, including customer service and hardware circuit modifications needed to tabulate numbers, create mathematical tables, add, subtract, multiply, reproduce, verify, crossfoot, create tables of differences, create tables of logarithms and perform Lagrangian interpolation, all to solve differential equations for astronomical applications.
		Eckert understood the significance of his laboratory, keenly aware of the advantage of scientific calculations performed without human interventions for long stretches of computation.

	Computer programming (Site not responding. Last check: 2007-10-25)
		One early programmer known to have completed all the steps for unaided computation, including compiling and testing, is Wallace J. Eckert.
		One difference between Eckert and today's programmers is that the example of his work influenced the Manhattan project.
		His work was recognized by astronomers from Yale University Observatory, Princeton University Observatory, U.S. Naval Observatory, Harvard College Observatory, Student's Observatory of the University of California, Ladd Observatory of Brown University and Sproul Observatory of Swarthmore College.

		For small enough differences, this linear operation was accurate enough for use in navigation and astronomy in the Age of Exploration.
		The uses of interpolation have thrived in the past 500 years: by the twentieth century Leslie Comrie and W.J. Eckert systematized the use of interpolation in tables of numbers for punch card calculation.
		In our time, even a student can simulate the motion of the planets, an N-body differential equation, using the concepts of numerical approximation, a feat which even Isaac Newton could admire, given his struggles with the motion of the Moon.
