| Leopold Löwenheim: Leopold Löwenheim (1878-1957) was a German mathematician who worked on mathematical logic. He is best known for the Löwenheim-Skolem theorem, which states that every first-order theory with an infinite model also has a countable model.

Hartry Field on Loewenheim - Dictionary of Arguments
I 131 Löwenheim-Skolem/downward/Field: says that there must be no uncountable models for 1st order consistent theories. Compactness theorem/Löwenheim-Skolem/upward: says that each 1st order space-time theory, according to which there are infinitely many space-time points, will have models, in which the set of the space-time points is mightier than the set of real numbers. Problem: then the representation theorem does not apply. >Representation theorem._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
