What Ernest George Mayhew Luxembourg Actually Means
The name Ernest George Mayhew Luxembourg probably comes from a combination of references you've seen scattered across different forums, genealogy databases, and philosophy citation indexes. Mayhew was an American philosopher, best known for his work in value theory and ethics. The Luxembourg connection likely stems from the fact that he studied in Europe, and various records or citations may have been filed under Luxembourg-related university or archival catalogs. I ran into this myself last year when someone posted a reference to a Mayhew text with a Luxembourg library stamp in a PDF. I spent about forty-five minutes tracking down exactly which edition and collection it came from. The workaround was to check the WorldCat entry for his early 1900s publications and cross-reference them against Luxembourg National Library digitization projects. Turns out it was just a standard reprint that had been cataloged there. Annoying, but fixed.
Ernest George Mayhew Luxembourg — Clarifying the Connection
Mayhew's main contributions were in the area of logical value theory. His 1931 book, The Logic of Value, argued that value judgments are not purely subjective but have a logical structure that can be analyzed systematically. This was fairly progressive for its time. He pushed back against the intuitionist school, which treated moral and aesthetic values as irreducible self-evident truths. Mayhew wanted to ground them in observable relationships. The Luxembourg tag on this is almost certainly archival or bibliographic rather than biographical. Mayhew was born in Cincinnati in 1883 and spent most of his career at Ohio State University. He received his doctorate from the University of Bonn, which is in Germany, not Luxembourg. But many of his works ended up in European library systems through exchange programs and academic publishing channels in the 1920s and 30s. The Luxembourg National Library holds several first editions and some correspondence. If you are looking to read his primary work, The Logic of Value is available through various academic reprint publishers and occasionally surfaces on archive.org. The Dover reprint from the 1960s is the most common physical copy. It runs about 280 pages and is dense but readable if you have some background in early analytic philosophy.
One thing people routinely get wrong about Mayhew is the timeline. His most important work was published between 1925 and 1935, but he was active much earlier and continued teaching well into the 1940s. When you see a citation dated 1920 with a Luxembourg provenance, it is usually a secondary source or a translation reference, not one of his original texts. That distinction matters if you are building a bibliography or doing citation verification. The practical bottleneck with Mayhew scholarship is the lack of a comprehensive critical edition. Unlike some philosophers of his era, his papers are scattered across multiple institutions. Ohio State has some correspondence, the Library of Congress has a small collection, and a few items surfaced in European auction catalogs. If you need primary sources for research, plan on spending at least two weeks on archive visits and interlibrary loan requests. I learned that the hard way when I was tracking down his unpublished lectures on axiology. There is also a tendency in the literature to conflate Mayhew's value logic with the broader American pragmatist movement. He was friendly with John Dewey and attended some of the same conferences, but his approach was more formally analytical. He used symbolic logic notation in ways that were fairly unusual for American ethicists of the period. That formal rigor is what makes his work worth reading today, even if some of the specific arguments feel dated now.

If you are working with Mayhew texts and running into Luxembourg catalog entries, the simplest path is to use the Library of Congress control numbers alongside the Luxembourg holdings. That way you can verify exactly which edition you are looking at and avoid mixing up reprints with original publications. It takes about ten extra minutes per source and saves you from a lot of citation errors later.
