Robinson, Abraham (1918-74). On the mechanization of the theory of equations. Offprint from Bulletin of the Research Council of Israel 9F (1960). 47-70pp. 241 x 170 mm. Without wrappers. Very good. Presentation Copy, inscribed by Robinson to Martin Davis (1928-2023) on the first page: "To Martin Davis Cordially A. R. 4.5.61." First Edition, Offprint Issue. Robinson is best known for developing nonstandard analysis, which reincorporated infinitesimal and infinite numbers into mathematics. In the present paper, which addresses "the problem of how to induce a machine, more particularly a digital computer, to prove mathematical theorems somewhat after the fashion of (certain) human beings," he constructed "a semantically complete calculus for the formulation of the elementary theory of equations" leading to "the formulation of a proof strategy for such problems" (p. 47). .

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.
