Source-derived summary

Kaj Ulrik Linderstrøm-Lang (29 November 1896 – 25 May 1959) was a Danish protein scientist, who was the director of the Carlsberg Laboratory from 1939 until his death.

His most notable scientific contributions were the development of sundry physical techniques to study protein structure and function (especially hydrogen–deuterium exchange), and his definitions of protein primary, secondary,

tertiary and quaternary structure.

Linderstrøm-Lang devoted himself to protein science and trained a generation of eminent protein scientists. He maintained a fun atmosphere in his laboratory with Christmas parties and trips to the Tivoli amusement park in Copenhagen. Linderstrøm-Lang was also a writer, musician and story-teller, and active in the resistance movement against the Nazi occupation of Denmark.

Research and career

Early work

Linderstrøm-Lang began as a physicist. Only a year after the publication of the Debye–Hückel theory, Linderstrøm-Lang applied it to proteins and contributed in defining the term isoionic point. In particular, he formally considered the ensemble of protonation states. Linderstrøm-Lang began in the Carlsberg laboratory under its second director S. P. L. Sørensen (who invented the pH scale). 1949 volumetric studies showing that the interior of proteins has very few charges and, hence, is likely to be hydrophobic.

Editorial analysis

Why this record matters

“Kaj Ulrik Linderstrøm-Lang” is worth following because a concise public description often conceals a longer documentary argument. Here, Ulrik, Linderstrøm-Lang and Danish provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 31, 2026. The linked authority identifier is Q6348816. VIAF identifies the subject as 23611908. The Library of Congress control number is n85830912. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1896, 1959, 1939 and 1949.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
