There are no significant discrepancies between this article and reference 2, and it is more accessible. More details on the numerical work carried out by Walther are given in reference 3. I note that A.S. Householder, R. Sauer, E.L. Stiefel, John Todd, and A. Walther founded the Springer journalNumerische Mathematikin 1959; the 65th volume is now being issued.
2. British Intelligence Objectives Subcommittee, Report No. 79, "Applied Mathematical Research in Germany, with Particular Reference to Naval Applications," London, Her Majesty's Stationery Office, 1945,65 pp. Declassified December 1947. I mislaid or mislent my copy of this report some years ago. A copy was recently located in the British Library, London, by Robert D. Ryan of the European Office of Naval Research. I know of no other original. A copy has been made and is available at Millikan Library of Caltech. [Editor's note: There is at least one other original in existence, at the Linda Hall Library, Kansas City, Mo., which I saw in 1978. - P.E.C.] My "Oberwolfach, 1945" (pp. 19-22 inISNM 64 General Inequalities, Vol. 3, E.F. Beckenbach and W. Walter, eds., 1983, Birkhaeuser, Basel, Switzerland) is an informal account of part of reference 2. It is preceded (pp. 3-18 in the same book) by Irmgard Suess' "The Mathematical Research Institute Oberwolfach Through Critical Times."
3. A. Walther, ed., "Field Information Agencies Technical Review of German Science, 1939-1946,"Applied Mathematics, 5 vols., Dieterich'sche Verlagsbuchhandlung, Wiesbaden, Germany, 1948. A copy of this is also in the Millikan Library of Caltech. However, it was printed on poor paper and is deteriorating.
