Hempel studied mathematics, physics, and philosophy at the Universitiy of Göttingen, Heidelberg and Berlin.

 Carl Gustav Hempel [Internet Encyclopedia of Philosophy]
Hempel studied at the Realgymnasium at Berlin and, in 1923, he was admitted at the University of Gottingen where he studied mathematics with David Hilbert and Edmund Landau and symbolic logic with Heinrich Behmann.
Hempel was very impressed with Hilbert's program of proving the consistency of mathematics by means of elementary methods; he also studied philosophy, but he found mathematical logic more interesting than traditional logic.
Hempel and Oppenheim's essay 'Studies in the logic of explanation', published in volume 15 of the journal Philosophy of science, gave an account of the deductive-nomological explanation.

 Princeton - News - Philosopher of Science Carl G. Hempel Dies
PRINCETON, N.J. Carl G. Hempel, a philosopher of science who refined and defended the approach known as logical positivism or logical empiricism, died Sunday, November 9, of pneumonia at the Windrows at Forrestal care facility.
While Professor Hempel remained a logical empiricist throughout his career, he was substantially influenced by a colleague at Princeton, the historian of science Thomas Kuhn, who urged that the formalist perspective of logical empiricism be replaced by a pragmatic view of the history, sociology and psychology of science.
Professor Hempel held Guggenheim and Fulbright fellowships and served as a fellow at the Center for Advanced Study in the Behavioral Sciences and as an honorary research fellow in philosophy at the University College, London.

Such a speaker asserts the Russellian singular proposition that Hempel lived on Lake Lane in Princeton; the sole constituents of this proposition are Hempel himself and the property of having lived on Lake Lane in Princeton.
For instance, he leaves open the possibility that the semantic content of 'Carl Hempel' is (roughly) the same as that of 'the thing that is sentient and is identical with z', under an assignment of Hempel to the variable 'z'.
Jill believes that (3) is false because she confuses the singular, Russellian proposition that (3) semantically expresses with the various descriptive propositions that she could use (3) to assert and convey, or that would be conveyed to her by assertive utterances of (3), for instance, the proposition semantically expressed by (11).

 Raven paradox - Wikipedia, the free encyclopedia

Carl G. Hempel, 92, University Professor of Philosophy at Pitt from 1976 until his retirement in 1985, died Nov. 9, 1997, at a nursing facility near his home in Princeton Township, New Jersey.
It disagrees with Hempel's model, but, as Salmon himself has emphasized, Hempel's work was his own point of departure." With Paul Oppenheim, Hempel in 1948 developed a logically precise theory known as the Deductive-Nomological, or Covering Law, Model of Explanation, which sees scientific laws and theories as systematizing otherwise unwieldy bodies of particular empirical claims.
Hempel was the author of the books "Aspects of Scientific Explanation and Other Essays in the Philosophy of Science" and "Philosophy of Natural Science," which has been translated into 10 languages.

 Theories of Explanation [Internet Encyclopedia of Philosophy]
Hempel accepted IS arguments as explanatory just to the extent that they approximated DN explanations by conferring a high probability on the event to be explained.
Hempel's dissatisfaction with statistical explanation was at odds with modern science, for which the explanatory use of statistics had become indispensable.
Hempel's view might be defended here by claiming that when our theories do not allow us to predict a phenomenon with a high degree of accuracy, it is because we have incomplete knowledge of the initial conditions.

 The St. Petersburg Paradox   (Site not responding. Last check: 2007-10-09)
Professor Carl Hempel, who invented this paradox, believes that a purple cow actually does slightly increase the probability that all crows are fl.
Hempel's belief is that observing a non-fl object actually does confirm the "all crows are fl" law, but only to an infinitesimal degree.
The reason the procedure seems strange, Hempel says, is that the class of objects on earth that are not crows is so enormously large compared to the number of crows that the degree to which a non-raven that is not fl confirms the hypothesis is negligible.

 Scientific Explanation
Hempel's response (1965, 360ff) is that the occurrence of “caused” in (2.4.1) should not be left unanalyzed or taken as explanatory just as it stands.
According to Hempel, it is the implicit claim that some such law holds that “distinguishes” (2.4.1) from “a mere sequential narrative” in which the spilling is said to follow the impact but without any claim of causal connection — a narrative that (Hempel thinks) would clearly not be explanatory.
As we have seen, both Hempel and Salmon, as well as most subsequent contributors to the literature on statistical explanation, have tended to assume that statistical theories that assign a probability to some outcome strictly between 0 and 1 should nonetheless be interpreted as explaining that outcome.

 Carl Hempel and A. J. Ayer
CARL HEMPEL AND A. The verification theory of meaning put forward by Moritz Schlick in 1932 lost its appeal in the following years.
The fundamental Positivist tenet of meaning, Hempel said, is that non-analytic knowledge is based on experience.
Through a similar logical argument Hempel showed that The theory of falsifiability in principle can be shown to have the same kinds of problems and therefore also must be set aside.

Hempel's clarifications pave the way: A scientific theory might be likened to a complex spatial network: Its terms are represented by the knots, while the threads connecting the latter correspond, in part, to the definitions and, in part, to the fundamental and derivative hypotheses included in the theory.
Hempel espouses, says that our operational concepts, as well as higher order concepts, may contain aspects that are invisible, unobservable, not only for today, but for always.
Hempel says that we must be very rigorous, in two senses, when we consider the clarity of our scientific language (evidence or concept): The meaning of a given expression presupposes that the conditions of its application are (1) well determined for every user of the language and are (2) the same for all users.

 FSuppe Abstract   (Site not responding. Last check: 2007-10-09)
Hempel's provisos papers widely are regarded as repudiating his earlier influential work.
I argue that Hempel's provisos views (a) are modest extensions of ideas found in his 1934 dissertation and papers written during his 1935-39 Belgium exile and (b) were fully articulated by 1945.
In his provisos problem, Hempel had his finger on a fundamental philosophical problem how scientific theories connect with observational or experimental results, but his basic positivistic/logical-empiricistic commitments precluded solution of the problem.

Carl Gustav Hempel (1905—1997) was one of the preeminent figures in the philosophical movement of logical empiricism.
He was a member of both the Berlin and Vienna circles, fled Germany in 1934 and finally settled in the US where he taught for many years in New York, Princeton, and Pittsburgh.
The essays in this collection come from the early and late periods of Hempel’s career and chart his intellectual odyssey from a rigorous commitment to logical positivism in the 1930s (when Hempel allied himself closely with Carnap) to a more sociological approach close in spirit to the work of Neurath and Kuhn.

Hempel is lucid and patient, although his observations are sometimes a bit superficial, especially when he frames his mind in 1st order logic and fears to go anywhere beyond.

Construing prediction deductively, Carl G. Hempel developed this notion into influential analyses of testing, confirmation, theories, and explanation.
In his provisos problem, Hempelhad his finger on a fundamental philosophical problem how scientific theories connect with observational or experimental results, but his basic positivistic/logical-empiricistic commitments precluded solution of the problem.
I suggest that Hempel's early work in Germany and Belgium is crucial to interpreting Hempel's later career, that his most famous and influential work may be somewhat plodding development of his juvenilia, and that his intellectual debts to Paul Oppenheim may be underestimated.
