Morgan Ward (1901-1963) Was An American Mathematician, A Professor Of Mathematics At The California Institute Of Technology. Ward Received His Ph.D. From Caltech In 1928, With A Dissertation Entitled The Foundations Of General Arithmetic; His Advisor Was Eric Temple Bell. He Became A Research Fellow At Caltech, And Then In 1929 A Member Of The Faculty; He Remained At Caltech Until His Death In 1963. Among His Doctoral Students Was Robert P. Dilworth, Who Also Became A Caltech Professor. Ward Is The Academic Ancestor Of Over 450 Mathematicians And Computer Scientists Through Dilworth And Another Of His Students, Donald Darling. Ward's Research Interests Included The Study Of Recurrence Relations And The Divisibility Properties Of Their Solutions, Diophantine Equations Including Euler's Sum Of Powers Conjecture And Equations Between Monomials, Abstract Algebra, Lattice Theory And Residuated Lattices, Functional Equations And Functional Iteration, And Numerical Analysis.He Also Worked With The National Science Foundation On The Reform Of The Elementary School Mathematics Curriculum, And With Clarence Ethel Hardgrove He Wrote The Textbook Modern Elementary Mathematics (Addison-Wesley, 1962). Ward's Works Are Collected In The Caltech Library. A Symposium In His Memory Was Held At Caltech On November 21-22, 1963. Signed by Author(s).

Hardcover. Condition: Near Fine. No Jacket. 2 volumes. Volume 1 appears to be a second edition, but has been signed by Ibragimov on the front end page. Volume two - first edition. Ibragimov died in November of 2018. The boards are the slightest touch edge rubbed, but remain otherwise strong and sturdy. Internally, there is a previous owner's signature under the front board (the same owner to whom Ibragimov inscribed the book to) of Volume 1 and on the front end page of Volume 2. There are no other markings or inscriptions, and the pages throughout both books are pristine, crisp and complete. The bindings are secure. JK.

Wilkes, Maurice Vincent (1913- ). A method of solving second order simultaneous linear differential equations using the Mallock machine. Offprint from Proceedings of the Cambridge Philosophical Society 36, part II (April 1940). Original buff printed wrappers. Signed by Wilkes on the front wrapper. [1], 204-208 [2]pp. 257 x 184 mm. Provenance: Maurice Wilkes. First edition, offprint issue. Wilkes directed the design and construction of EDSAC, the first readily usable, full-scale stored-program computer. EDSAC was preceded in operation by the Manchester "Baby"prototype stored-program machine which ran for only a short time in 1948; in America, BINAC was probably running programs about the same time, but it too was a very short-lived machine. In addition to developing EDSAC, Wilkes was responsible for a number of programming innovations, such as labels, macros, and microprogramming, that became standard in the computer industry. He studied physics at Cambridge University, where he received his Ph.D. in 1936 with a thesis based on work performed in the Cavendish Laboratory on the propagation of very long radio waves in the ionosphere. While engaged in postgraduate research on this topic, he was allowed to use Cambridge University's model differential analyzer to solve a difficult equation. This machine, which Wilkes found "irresistible" (Wilkes 1985, 25), inspired an abiding interest in automatic computing. At the end of 1936, Wilkes was put in charge of Cambridge's model differential analyzer, and the following year he joined the staff of the university's newly founded Mathematical Laboratory, becoming its director after the close of World War II. The Mathematical Laboratory (renamed the Computing Laboratory in the 1960s) played a critical role in the development of the electronic digital computer. One of Wilkes's tasks during 1937 was to gather information about the special-purpose calculating machine invented by R. R. M. Mallock (of Cambridge's Engineering Department), which the Mathematical Laboratory was interested in purchasing. Wilkes described the machine as follows: The Mallock machine was an analogue device and was capable of solving ten simultaneous linear equations in ten unknowns. It was based on the use of tapped transformers with the windings connected to form a network. The accuracy obtainable from such an arrangement might be expected to be very low because of losses in the transformers. What made the Mallock machine give a useful accuracy-one part in 1000 in favourable cases-was the use of a highly ingenious feedback circuit, known as a compensator, associated with each transformer. As a piece of electronics, this was well ahead of its time. . . . In order to solve a set of simultaneous equations, one had first to set the coefficients on an array of digital switches. The roots were then obtained by adjusting another switch until a galvanometer showed zero. This had to be done for each root in turn. When I got to know him, Mallock was experimenting with a device based on the use of telephone relays for performing this operation automatically and printing the result on a paper strip. Although this gear came with the Mallock machine, it was not fully developed and we made no attempt to use it. However, it gave me my first introduction to the use of telephone relays in computing, or rather control, circuits and to some of the tricks one can play with them (Wilkes 1985, 29).

Bound in the original wraps, stamped in black. This volume was among several dozen books from Temple Rice Hollcroft's library that we were lucky enough to purchase at auction in New Jersey. The American mathematician Temple Rice Hollcroft (1889 - 1967) received B.S. in 1912 and A.B. in 1914 from Hanover College and then A.M. in 1915 from the University of Kentucky. He received his Ph.D. in 1917 from Cornell University under Virgil Snyder. Hollcroft was a mathematics professor at Wells College from 1918 to 1954, from which he retired as professor emeritus. Hollcroft served for 14 years as Associate Secretary of the American Mathematical Society. In 1932 in Zurich he was an Invited Speaker of the International Congress of Mathematician (ICM). His subject was THE GENERAL WEB OF SURFACES AND THE SPACE INVOLUTION DEFINED BY IT. Being invited to talk at the ICM has been called "the equivalent of induction to a hall of fame." - from Wikipedia.
