    IN THE EIGHTH GRADE AT HOPEWELL-LOUDON SCHOOL, BASCOM, SENECA COUNTY, OHIO, in the school year 1955–56, in Mrs Patricia Hoffert's class. This is the first dated evidence of where the family lived in the Ohio years. Until now the only fixed point between the Boston landing of 7 July 1949 and his B.S. at Case in Cleveland in 1964 was the 1950 census, which has his father a farm hand in Liberty Township, Mercer County, in far western Ohio. Bascom is 80 miles north-east of that, south of Fostoria in Seneca County. His twin brother and sister Kalvis and Līga are in the two third-grade photographs of the same yearbook — the three grades (8, 3, 3) that their birth years (Sep 1942, Nov 1946 ×2) require. Hopewell-Loudon is a single K–12 school, so he may well have gone on to finish high school there, about 1960, before Case; that is a lead, not a fact.

    In the Universitas (Latvian student periodical) article 'L! K! A!' (Latvian Student Corporations), section 'STUDIJU UN DARBA GAITAS', the paragraph on the fraternity Talavija reads, as read by eye on the whole page: 'Talavijā 1962/63/64. g. uzņemtie studenti: Jānis Priedite [no macron visible], ing. el., Univ. of Cincinnati; Pēteris Danenbergs, chem., Case Inst. of Technol.; Ojārs Mantenieks, oec., Fenn College, Cleveland; …' (a list of about sixty students and their fields and universities). So the page confirms Pēteris Danenbergs, chemistry, Case Institute of Technology, admitted to Talavija in the years 1962–64 (the three years are given for the whole list, not for him). The Alpha Chi Sigma membership claimed by Laiks (pl-034) is not on this page. The sweep's 'admitted 1962/64' is thus a loose reading of '1962/63/64'. No other Danenbergs on the three pages (pp.56–58) of this article in the library text. The issue date 1 Oct 1964 is the recheck's/library's; the masthead was not read.

Kalifornijas U Losandželosā' = Dienvidkalifornijas Universitāte (University of SOUTHERN California) in Los Angeles; the same abbreviation 'D. Kalifornijas U' is used later in the entry for the medical school where he has taught since 1976, which is certainly USC, and the entry writes plain 'Kalifornijas U Santa Barbarā' (University of California) without the D.

    Translation: and the University of California, Santa Barbara, with a doctorate in bioorganic chemistry in 1970

    Ph.D. in bioorganic chemistry, University of California, Santa Barbara, 1970. CONFLICT: USC's own 2011 faculty page says 'PhD 1970 Chemistry - University of Southern California'. I believe the encyclopaedia (and Peter's own recollection of Santa Barbara) over the USC page, because his three earliest papers, all 1971 in Biochemistry, are with Daniel V. Santi on phenylalanyl-tRNA synthetase — Santi's UCSB chemistry-department subject — and because the USC page's education block is visibly sloppy ('Univeristy'). Recorded both ways; Peter can settle it.

36. Peter V. Danenberg, University of Southern California.

    Peter V. Danenberg, a Biology and Biochemistry scholar from University of Southern California, has 191 publications recorded across 54 years, from 1971 to 2024. … H-index 59 … Citations 13130

    Publication record, three independent counts: ResearchGate 356 publications and 20,055 citations (Oct 2026); research.com 191 publications 1971–2024, h-index 59, 13,130 citations in Biology and Biochemistry (Aug 2026), peak output 13 papers in 2002; PubMed 196 indexed papers 1971–2022. Semantic Scholar splits him over two author records totalling about 340 papers and 19,000 citations. Field: thymidylate synthase, 5-fluorouracil, fluorinated pyrimidines, and quantitative gene-expression predictors of chemotherapy response.

37. Priekšsacīkstes sākušās (sports column), Laiks, 3 April 1971, p. 6, Laiks, 3.04.1971 (date from the library record; masthead not read), Periodika issue 738049, article DIVL494, doc 51952188, viewer p. 6.

    Milvoku Auseklim bez iepr. minētiem vēl darbojās K. Danenbergs /11/, V. Čakāns /10/, P. Danenbergs /7/ un U. Grinbergs /6/.

    Translation: Besides those mentioned before, K. Danenbergs (11), V. Čakāns (10), P. Danenbergs (7) and U. Grinbergs (6) also played for Milwaukee Auseklis.

    Laiks sports column (article headline per the library: 'Priekšsacīkstes sākušās'), read by eye on the whole page: in a report on a game of Milwaukee Auseklis (the head of the article was not read; the preceding text names Indianapole VV and its scorers K. Šteinmanis /24/, Kalepu /21/, Fricsonu /18/, M. Graudiņš /9/, V. Lerchs /9/), the closing sentence gives the other Milwaukee players: 'Milvoku Auseklim bez iepr. minētiem vēl darbojās K. Danenbergs /11/, V. Čakāns /10/, P. Danenbergs /7/ un U. Grinbergs /6/. /J.Z./' (Besides those mentioned before, K. Danenbergs 11, V. Čakāns 10, P. Danenbergs 7 and U. Grinbergs 6 also played for Milwaukee Auseklis.) So both Danenbergs, K. (figure 11) and P. (figure 7; presumably points, not stated in the passage read), played for Milwaukee Auseklis; the sweep's 'K. un P. Danenbergi ... pa 6' was wrong (11 and 7; the library OCR text has '/!/' where the page prints /7/). Signed J.Z. The date (3 April 1971) is the library's; the masthead was not read.

38. Priekšspēles Milvokos (sports report, signed Ivars Veldre), Laiks, 14 April 1971, p. 6, Laiks, 14.04.1971 (date from the library record; masthead not read), Periodika issue 738056, article DIVL633, doc 51953675, viewer p. 6.

    No milvokiešiem veiksmīgākie J. Tupesis 17, E. Ezeriņš 16, V. Čakāns 11, K. Danenbergs 6, P. Danenbergs 5.

    Translation: Of the Milwaukee players the most successful were J. Tupesis 17, E. Ezeriņš 16, V. Čakāns 11, K. Danenbergs 6, P. Danenbergs 5.

    Read by eye on the whole page, right-hand column, in a report on the Middle States preliminary round at Milwaukee (the heading was not read; the library has 'PRIEKŠSPĒLES MILVOKOS'): after the volleyball games 'notika arī basketbola priekšsacīkšu spēle, kurā sastapās Milvoku Auseklis ar Čikagas DV' (a basketball preliminary game took place, Milwaukee Auseklis against Chicago DV); Chicago won 71-65. 'No milvokiešiem veiksmīgākie J. Tupesis 17, E. Ezeriņš 16, V. Čakāns 11, K. Danenbergs 6, P. Danenbergs 5.' (Best of the Milwaukee players: ...). So the sweep's '5-team tournament in Chicago' is wrong: the page says the game was in Milwaukee and was Auseklis v. Chicago DV, and the figures are K. Danenbergs 6 and P. Danenbergs 5, not 'pa 6' for both. This finding is for P.; pl-086 is the same sentence for K. Signed IVARS VELDRE. The date (14 April 1971) is the library's; the masthead was not read.

    Inhibition of hexokinase by multisubstrate analogs. Peter V. Danenberg, Kathleen D. Danenberg

    He and Kathleen published together, as husband and wife, from the first years at USC — twenty years before Response Genetics. Two early joint papers: Danenberg PV, Danenberg KD, "Inhibition of hexokinase by multisubstrate analogs", Biochimica et Biophysica Acta 1977 (cited 21 times); and Danenberg PV, Danenberg KD, Biochemistry 17 (1978), 4018–4024, on the 5,10-methylene tetrahydrofolate dependence of thymidylate synthetase binding — the paper his own later work cites as reference 21. The joint bibliography runs on for decades.

43. Peter V. Danenberg — Research Description.

    Research Topics: Cancer Cell Biology, Protein Chemistry/Enzymology, DNA & RNA

    Research description in his own words on the USC faculty page: 'The work in this laboratory is directed at understanding the mechanisms by which cytotoxic anti-cancer drugs interact with their intracellular targets and the molecular factors and events determining response of tumors to drugs… By using quantitative PCR, we have shown substantial variation among tumors in the degree of expression of genes of drug-targeted enzymes such as thymidylate synthase.' Listed research topics: Cancer Cell Biology, Protein Chemistry/Enzymology, DNA & RNA. The same text, collected in 2015, is already in his bio in data/people.
