This is a list of names from Marquis Who's Who, 1926 edition (OCR'd version at archive.org). OCR errors in the source are duplicated here; in some cases, that caused more errors with the automatic parsing. Please consult the original scan here.
This is a somewhat messy list, which I am gradually cleaning. List-cleaning involves two components: making sure that the names in Marquis are the names in Wikipedia (fixing OCR glitches and restoring omitted entries), and making sure that the bluelinked names in Wikipedia represent the same people as in Marquis.
Being in the 1926 Marquis is a very strong (though not definitive) indicator of notability, so feel free to create articles based on redlinks. However, PLEASE DO NOT REMOVE BLUELINKED NAMES; rather, add a checkmark ({{checkmark}}). Do not add checkmarks to bluelinks without first verifying that the Wikipedia page refers to the same person as the original Marquis text. If the bluelink does not lead to the right article, do some searching – maybe the right article exists under a slightly different name. Either way, just add a disambiguation tag. If the bluelink leads to a redirect to a related article, please do not add checkmarks to these; rather, add a note that this is a redirect.
