LARRY SPRUCH 1923-2006

 

INTRODUCTION

 This is a website in honor of Larry Spruch, to recognize his many years of contributions to theoretical physics and other important areas of our civilization.   Some of his close associates have prepared short articles describing specific aspects of his work, and, in most cases, the work with which each of these colleagues was most closely associated. Larry has himself prepared a number of specialized articles for this collection. Both kinds of works can be accessed by clicking either on the author's name or on Spruch 1 through 10 below. Other linked material includes selections from a book of science quizzes by Larry and his wife Grace, an article by Leonard Rosenberg written on the occasion of Larry's 70th birthday, and some personal appreciations by several other of his friends and colleagues. as well as a short personal note by Larry himself. His complete bibliography appears on this page, and his resume can be accessed as well.

Some original articles can be accessed through hyperlinks in the  bibliography, principally those appearing in APS journals, through its PROLA archive. This archive goes back to the first issue of Physical Review in 1893. Some hyperlinks in the pdf versions of the guest articles have also been established, mainly through PROLA, and these can be reached by clicking on boxed references in the guest articles. You are permitted to access the original articles provided you are using your institution’s website and provided that it subscribes to the electronic versions of the cited journals; otherwise you can still obtain the abstract and references. Some of Larry’s works (ones which are not electronically available) are also available from this home page, in scanned html versions.
