	Cornelius Lanczos
		Cornelius Lanczos (LÃ¡nczos KornÃ©l), born KornÃ©l LÃ¶wy (February 2, 1893â“June 25, 1974), was a Hungarian mathematician and physicist.
		Lanczos served as assistant to Albert Einstein during the period 1928â“29.
		In 1962, Lanczos showed that the Weyl tensor, which plays a fundamental role in general relativity, can be obtained from a tensor potential which is now called the Lanczos potential.

	Lanczos biography
		Cornelius Lanczos was born Kornél Löwy but when there was a reaction in Hungary against German names he, along with large numbers of his countrymen, changed his name from the German form and became Kornél Lánczos (or rather, Lánczos Kornél since Hungarians put the family name first).
		Lanczos continued to work on his first love of relativity and corresponded with Einstein both on a scientific level and as a friend.
		Lanczos was therefore delighted to receive an offer from Schrödinger to head the Theoretical Physics Department at the Dublin Institute for Advance Study in Ireland.

		Lanczos, a physicist and applied mathematician, had already been very successful at devising algorithms for analyzing a variety of mathematical models, and he was well acquainted with the challenges of computation on desk calculators.
		Lanczos, too, discussed the solution of linear systems using the recurrence of his minimized iterations [4], and recognized that it was mathematically equivalent to the method of conjugate gradients [5], another noteworthy NBS discovery discussed elsewhere in this volume.
		Lanczos, too, came under investigation for allegedly being a communist sympathizer, and this may have contributed to his decision to begin a third exile, in 1952, and then permanently in 1954, to the Dublin Institute for Advanced Studies.

		This may correspond to applications where one is interested in the smallest eigenvalue(s) of a selfadjoint elliptic differential operator L of order s, in which case one would choose K to be the inverse of L on its range.
		For this example the precise asymptotic behaviour of the approximation error after k Lanczos steps is determined by using the connection between the Lanczos iteration and orthogonal polynomials.
		After these preliminaries the strong asymptotic behavior of the error of the Lanczos approximation to the smallest eigenvalue of L can be determined.

	NBS-Developed Method Named `Algorithm of the Century'
		The algorithm, actually a class of methods, known today as Krylov subspace iteration, saw its genesis in work done by Magnus Hestenes, Eduard Stiefel, and Cornelius Lanczos of the Institute for Numerical Analysis operated by NBS at UCLA in the late 1940s and early 1950s.
		Hestenes and Lanczos were NBS staff members, while Stiefel was a visitor from the ETH in Zurich.
		Early Krylov methods were proposed by Lanczos and then by Hestenes and Stiefel, who called their technique the conjugate gradient method.

	Applied Analysis
		Comment: Lanczos' work is a fine, thorough text that covers most areas of advanced analysis in a readable style.
		Consequently, the book is not "one-shop stopping" for all the mathematical techniques that an electrical engineer or physicist might require in his bag of tricks....
		He knew it all, and was one of the inventors of the fast Fourier transform.

		Lanczos is more literate and much more humble.

		We examine a curious approximate differentiation rule of Cornelius Lanczos.
		Lanczos' rule is shown to be a generalized derivative with convergence properties that are reminiscent of the convergence of Fourier partial sums.
		The effect of data errors on the rule is examined both numerically and analytically and a best possible order of approximation is established.

		However, it is noted by Lanczos that "it is exactly this apparent triviality which makes d'Alembert's principle such an ingenious invention and at the same time so open to distortion and misunderstanding.".
		One of these consequences, related to gait analysis, is to allow the use of "kinematical variables", that is, velocities that are not the derivatives of actual position coordinates.
		The example cited by Lanczos is the spin of a top about its axis of symmetry, however one could extend this to think of the angular velocities of Euler angles.

		The Lanczos derivative is attributed to Cornelius Lanczos and is an integral-based, proper extension of the usual derivative.
		We show how this derivative may be expressed in probability terms using the uniform random variable.
		We also show how the Lanczos derivative and its higher-order analogs may be viewed as limits of integrals involving Legendre polynomials.
