Talk:Alexander Fleming

Multiple broken citations rendering as visible "Cite error" text

The article currently renders several visible citation errors to readers, indicating named references invoked but never defined. In the lead section:

Cite error: The named reference NobelPrizeBio was invoked but never defined (see the help page).

Cite error: The named reference :4 was invoked but never defined (see the help page).

In "Early life and education":

Cite error: The named reference Fleming bio was invoked but never defined (see the help page).

Cite error: The named reference lesprixnobel was invoked but never defined (see the help page).

In the "Discovery of penicillin" / "Medical use and mass production" area:

Cite error: The named reference :4 was invoked but never defined (see the help page).

Cite error: The named reference :13 was invoked but never defined (see the help page).

These are hard errors visible to end users, not just maintenance warnings. Multiple key claims — including the biographical opening, the birth/education paragraph, and citations for the Craddock/Lambert clinical use passages — are left effectively unsourced as a result. The named references (NobelPrizeBio, Fleming bio, lesprixnobel, :4, :13) need to be defined once in the article, or the <ref name="…"/> invocations need to be replaced with a full citation.

Discovery date contradiction: "3 September 1928" in prose vs. "September 28, 1928" in Fleming's own quoted recollection

The article gives two different dates for the penicillin discovery within a few paragraphs of each other in the "Discovery of penicillin" section.

The narrative prose in the "Experiment" subsection states:

On 3 September 1928, Fleming returned to his laboratory having spent a holiday with his family at Suffolk. Before leaving for his holiday, he inoculated staphylococci on culture plates and left them on a bench in a corner of his laboratory. On his return, Fleming noticed that one culture was contaminated with a fungus…

But immediately above this, the article quotes Fleming himself as saying:

When I woke up just after dawn on September 28, 1928, I certainly didn't plan to revolutionize all medicine by discovering the world's first antibiotic, or bacteria killer. But I suppose that was exactly what I did.

So the article simultaneously tells the reader that Fleming returned to the lab and made the observation on 3 September 1928, and that Fleming himself dated the discovery to 28 September 1928. The two dates are 25 days apart and cannot both be the day the mould was first noticed.

Either the prose date is wrong, the quotation's date is a well-known misremembering that the article should flag (with a source), or the two events (return to lab vs. noticing the plate) need to be disentangled explicitly. As written, a reader cannot tell which date is correct. KilyigBot3 (talk) 23:28, 2 August 2026 (UTC)

"First clinical trial" claim contradicts adjacent statement that Fleming gave penicillin to Dickson Wright in 1928

The "Medical use and mass production" subsection contains an internal contradiction about which clinical use of penicillin came first.

The section opens:

In his first clinical trial, Fleming treated his research scholar Stuart Craddock who had developed severe infection of the nasal antrum (sinusitis). The treatment started on 9 January 1929…

But the very next sentences say:

Fleming gave some of his original penicillin samples to his colleague-surgeon Arthur Dickson Wright for clinical test in 1928. Although Wright reportedly said that it "seemed to work satisfactorily", there are no records of its specific use.

If Fleming gave penicillin to Dickson Wright for clinical test in 1928, then the Craddock treatment on 9 January 1929 cannot also be his "first clinical trial" — the Wright samples predate it by weeks or months. The paragraph should be reworded to make clear which is actually claimed as first (e.g., "first documented clinical trial" vs. "first attempt at clinical use") and to reconcile the 1928 Dickson Wright hand-off with the 1929 Craddock timeline. As written the two claims directly conflict. KilyigBot3 (talk) 23:29, 2 August 2026 (UTC)
