  • Notes:

    Neugebauer's interests at the Akademisches Gymnasium, Graz, in mathematics, mechanics, and technical drawing foreshadowed his later work, but his interest in the required Greek and Latin was nil, so that when in 1917 His Imperial Majesty's Army offered enlistment to final-year students with consequent exemption from part of their final exams, he promptly accepted. After a year as a POW in Italy he entered the University of Graz to study electrical engineering and physics; upon transfer to Munich he attended lectures by Arnold Sommerfeld and Arthur Rosenthal. After a further move to Göttingen, his major professors became R. Courant, E. Landau, and E. Noether, all mathematicians. Here he learned Egyptian in order to study and eventually write his dissertation on Egyptian mathematics. In 1933 he was forced by the Nazis to leave Göttingen and found a haven in Copenhagen, whence he moved to Brown in his akmi year when conditions for work in Denmark proved impossible. Once in the United States he began writing solely in English, which he preferred, since, as he once said, it improved his style and interpretations—there are no dense musings on theory or method in his English-language works.Mathematics is both an independent universal and in its individual development embedded in its culture. Neugebauer's work from his dissertation to his death was always responsive to this duality. His work on the history of ancient mathematics and astronomy was extremely wide-ranging and influential (not always to the joy of those who believe all ancient wisdom culminates in Greek philosophy); he contributed as well to the bibliography of modern mathematics, founding and editing two international review journals, Zentralblatt flir Mathematik und ihre Grenzgebiete and later Mathematical Reviews. For ancient mathematics he founded and edited the journal Quellen und Studien zur Geschichte der Mathematik, Astronomie und Physik, as well as discovering and writing the history of Babylonian mathematics and astronomy, for which he learned Akkadian. Within classics he always emphasized the connections to other Near Eastern cultures' mathematics and astronomy. He discussed the concepts of roots and of zero known to the Babylonians, and showed that zero was known to Greek mathematicians (Exact Sciences, pp. 11-4, 26, pi. 2); he analyzed the earliest extant determination of longitude by Heron, which also produced one of the three known dates for Heron; and wrote often about fundamental methods and problems in the field. In 1938 he destroyed E. Meyer's "erstes sicheres Datum der Weltgeschichte," as it was based on a misunderstanding of the Egyptian "Sothic" period.He always held that skilled scientific and philological publication and analysis of sources (preferably new) were vastly to be preferred to superficial synthesis. Hence his papers on astronomical fragments in Plutarch and Galen and on many papyri. The last of these, which was his last publication, turned out to be a table of lunar positions known from third- to second-century B.C. cuneiform, but here in Greek from second- to third century A.D.— thus proving the extensive transmission of Babylonian astronomy to the Greeks and its use well after Ptolemy. With W. Kendrick Pritchett he published a very influential book on the Athenian calendars and several articles on ancient scientific instruments. He rightly insisted on the value and importance of astrological texts for establishing astronomical theory and ancient chronology and published the definitive collection of ancient Greek and Roman horoscopes, as well as numerous smaller pieces.His work on Greek astronomy, though not at the center of his interests (only about one quarter to one third of his over 300 publications), remains fundamental and often iconoclastic. From his early work on Apollonios and Heron and his provocative article on the conic sections to his demonstration that the Babylonians never discovered the precession of the equinoxes, contrary to the claims of some modern scholars, one can always see his insistence on a close and informed reading of the texts. His book The Exact Sciences in Antiquity is of permanent value and instructs on every reading (I have used it for a course on the history of ancient science). His analyses even of "standard" texts were always insightful and visual, accompanied by clear diagrams drawn by himself. Among his important contributions are his explanation of the geometrical origin of Eudoxos' "hippopede," his analysis of Apollonios' planetary theory (the "eccentric"), on Hipparchus as observer and collector of Babylonian observations, his studies of the geometry of Ptolemy's map-projection and of the astronomy of Hypsikles (ca. 150 B.C.), and his proof that Heraclides Ponticus had no heliocentric theory. These studies culminated in his Haup-twerk (in a classicist's view), History of Ancient Mathematical Astronomy, which covers Ptolemy and his major antecedents Apollonios and Hipparchus, then Babylonian astronomy, earlier Greek astronomy, and finally Roman and late antique astronomy (short work indeed is made of the trivial Egyptian astronomy; several Greek works, notably Geminus and Cleomedes, are redated). His reviews are often more valuable than the books reviewed, and always of great use—here I note especially the reviews of Mugler in which Neugebauer points out Mugler's unwarranted restriction to a small subset of the available sources; of Stahl, whose work is an example of the superficial handbook tradition he studies; and of the latest and wretched English translation of the earliest complete Greek mathematical text, Autolycus. Not only did he publish widely and often, he produced a corps of notable students and younger colleagues: A. Aaboe, A. Jones, D. Pingree, and G. J. Toomer (in alphabetical order) will be known to classicists (there are many others). Neugebauer had both a broad and deep view and his work as editor, teacher, and scholar profoundly altered our view of antiquity.
