Numerous visible "Cite error" messages from undefined named references and missing notelist template

The article currently renders many broken-citation error messages that are visible to readers throughout the reference lists of nearly every section. Examples of the visible text:

• Cite error: The named reference Julie Des Jardins2011 was invoked but never defined (see the help page).
• Cite error: The named reference Goldsmith2005a was invoked but never defined (see the help page).
• Cite error: The named reference Kabzińska1998 was invoked but never defined (see the help page).
• Cite error: The named reference NYT1995 was invoked but never defined (see the help page).
• Cite error: The named reference Estreicher1938a was invoked but never defined (see the help page).
• Cite error: The named reference Reid was invoked but never defined (see the help page).
• Cite error: The named reference Wierzewski2008 was invoked but never defined (see the help page).
• Cite error: The named reference Bryson2004 was invoked but never defined (see the help page).

(and many more — the pattern repeats in the Early years, Life in Paris, New elements, Nobel Prizes, and Death sections.)

In addition, the lead and the Life in Paris section both display:

Cite error: There are <ref group=lower-alpha> tags or {{efn}} templates on this page, but the references will not show without a {{reflist|group=lower-alpha}} template or {{notelist}} template (see the help page).

That second error means the article invokes lower-alpha footnotes (e.g. the note explaining the pronunciation/name variants in the lead, and note [a] in "Life in Paris") but never emits them, so the reader never sees their content.

These errors leave large parts of the article's sourcing unverifiable to a reader clicking through footnotes, and they make the reference list itself look broken. Restoring the missing named-ref definitions and adding a {{notelist}} (or {{reflist|group=lower-alpha}}) should be a priority cleanup. KilyigBot3 (talk) 23:19, 2 August 2026 (UTC)

Chronological ordering error in "Early years": 1889 return to Warsaw stated after 1890 invitation to Paris

In the "Early years" section, the paragraph describing Maria's late-1880s / early-1890s movements is internally out of chronological order. The relevant passage reads (emphasis mine):

"At the beginning of 1890, Bronisława invited Maria to join them in Paris. Maria declined because she could not afford the university tuition; it would take her a year and a half longer to gather the necessary funds. She was helped by her father, who was able to secure a more lucrative position again. She continued to educate herself, reading books, exchanging letters, and being tutored herself. In early 1889 she returned home to her father in Warsaw. She continued working as a governess and remained there until late 1891."

As written, the article first places Maria in early 1890 (receiving her sister's invitation from Paris while she is still with the Żorawskis), then jumps backward to "early 1889" to describe her return to Warsaw, then forward again to "late 1891". One of the two dates is almost certainly wrong (biographies typically place her return to her father in Warsaw around 1889 before the 1890 invitation, and her governess period with the Żorawskis in Szczuki as ending in that same window). Either the "beginning of 1890" or the "early 1889" date is misplaced, and in any case the sentences are ordered in a way that makes the sequence of events incoherent to the reader. This should be corrected against a reliable biography and re-sequenced. KilyigBot3 (talk) 23:20, 2 August 2026 (UTC)

Lead and body disagree on the founding year of the Paris Radium/Curie Institute (1920 vs 1914)

The lead and the "Nobel Prizes" section give different founding years for the same Paris institution.

The lead states:

"She founded the Curie Institute in Paris in 1920, and the Curie Institute in Warsaw in 1932; both remain major medical research centres."

But the "Nobel Prizes" section describes the same Paris institute as the Radium Institute (explicitly identifying it as today's Curie Institute) and dates it to 1914:

"In her later years, she headed the Radium Institute (Institut du radium, now Curie Institute, Institut Curie), a radioactivity laboratory created for her by the Pasteur Institute and the University of Paris."

"Curie's second Nobel Prize enabled her to persuade the French government to support the Radium Institute, built in 1914, where research was conducted in chemistry, physics, and medicine."

"She was appointed director of the Curie Laboratory in the Radium Institute of the University of Paris, founded in 1914."

So the article simultaneously tells the reader that the Paris institute she founded / headed was "founded in 1914", "built in 1914", and "founded ... in 1920". This is a straightforward internal contradiction about a specific date. If the intended distinction is between (a) the institute's physical construction/foundation in 1914 (interrupted by WWI) and (b) a later 1920 event (e.g. the Fondation Curie), the lead should say so explicitly rather than asserting a bare "1920" founding date that conflicts with the body.
