POST 19 FACT-CHECK REVIEW
Post: 2026-04-18-The-women-they-wrote-out-of-the-photo.md
Reviewed: 2026-04-16
Reviewer: Research agent + WebSearch verification
SUMMARY
The post is overwhelmingly accurate. Most biographical data, dates, and narrative claims match primary and secondary sources. Six specific issues require correction; one further ambiguity should be clarified; and two minor wording choices should be updated for precision.
CORRECTIONS REQUIRED
1. Kay McNulty – college is Chestnut Hill College, NOT Bryn Mawr
Post says: (implicit in the text – the post correctly names Chestnut Hill College) Status: CORRECT. The post states “Chestnut Hill College” and that is right. No correction needed here.
However, the task asked to verify “Bryn Mawr” – the post does NOT claim Bryn Mawr. This claim does not appear in the post. CONFIRMED CORRECT as written.
2. Jean Bartik – “one of only two women” math majors is WRONG
Post says (line 60): “one of only two women math majors at the college”
What sources say: Every source consulted – Wikipedia, MacTutor, Northwest Missouri State University’s own museum page – states that Bartik was the only student to major in mathematics that year, not merely “one of only two women.” She was the sole mathematics graduate, full stop. The research file (ENIAC_programmers.md, line 78) correctly states “the only female mathematics graduate that year,” and the web search confirms she was “the only student to major in mathematics.” Special courses (Modern Geometry, Theory of Numbers) were put on just for her.
CORRECTION: Change “one of only two women math majors at the college” to “the only mathematics graduate – male or female – in her graduating year.”
3. Betty Holberton – computer color is “gray-beige,” not just “beige”
Post says (line 75): “changed the computer’s exterior color from black to beige”
What sources say: Multiple authoritative sources (Wikipedia, AWIS, Betty Holberton obituaries, the Women_of_computing_research.md research file) consistently use the phrase “gray-beige” or “grey-beige.” The research file (line 60) also says “black to gray-beige.” The post simplifies this to just “beige,” which is technically imprecise – the specific tone is gray-beige.
CORRECTION: Change “from black to beige” to “from black to gray-beige.”
4. Arianna Rosenbluth – age at PhD is ambiguous: 21 or 22
Post says (line 221): “her PhD in physics from Harvard in 1949 – at age 22”
What sources say: This is a genuine ambiguity. Rosenbluth was born September 15, 1927. Her PhD was awarded in 1949. If the degree was conferred before September 15, 1949, she was 21; if after, she was 22. Sources are split: the IMS obituary and Radcliffe Institute both say age 22; other sources (X/Twitter citation of Xihong Lin) say age 21. The research file says “age 22.” The post says “age 22.”
Status: The post’s claim of “age 22” is consistent with the research file and the Radcliffe/IMS sources, which are the most authoritative. However, since the degree year is 1949 and her birthday is in September, the claim cannot be stated with certainty. This is a minor ambiguity; no correction is strictly required, but the wording “at age 22” is reasonable and supported by primary sources. Consider adding a note: “she turned 22 in September of that year.”
5. Klara von Neumann – age at death
Post says (line 163): “She was 52 years old.”
Verification: Born 18 August 1911, died 10 November 1963. Age at death: 52 years, 2 months, 23 days. CORRECT.
6. WITI Hall of Fame – the post says “Women in Technology International Hall of Fame,” but the official name is “Women in Technology International (WITI) Hall of Fame”
Post says (line 283): “inducted into the Women in Technology International Hall of Fame”
Status: This is the correct name. CONFIRMED CORRECT. No change needed.
7. “Grasshopper” memoir chapters: post says 8 chapters/6 drafts
Post says (line 156-157): “The memoir was to be divided into eight chapters and a postscript. She completed drafts for six of them”
What sources say: The research file (Women_of_computing_research.md, line 82) states exactly: “was to be divided into 8 chapters and a postscript. Drafts exist for 6 of them.” Web searches could not locate a source contradicting this from the original archive, and the Lost Women of Science podcast/Library of Congress records support the structure. CORRECT as written.
The specific phrase “not marketable” (used in the post) does not appear in web-accessible sources verbatim, but the rejection and the general fact of non-publication are widely confirmed. The Lost Women of Science podcast (Season 2, Ep. 1) discusses the rejection. The research file also records this as the reason. No correction required, but the exact quote “not marketable” should ideally be footnoted as paraphrased from oral history / podcast sources rather than a direct archival quote.
8. Klara von Neumann – “sand in dress” wording
Post says (line 165): “Her dress had been weighed down with 15 pounds of wet sand.”
What sources say: Wikipedia (Klara Dan von Neumann article) and the research file confirm “15 pounds of wet sand.” BAC 0.18% also confirmed by multiple sources. CORRECT.
9. Dauxois article – journal issue month
Post says (line 188-189): “In January 2008, physicist Thierry Dauxois published an article in Physics Today titled ‘Fermi, Pasta, Ulam, and a Mysterious Lady.’”
What sources say: The arXiv preprint was posted January 2008. The published reference in the blog (and in the research file) gives “Physics Today 61(1), pp. 55-57” – volume 61, issue 1, which is the January 2008 issue. The full title is “Fermi, Pasta, Ulam, and a mysterious lady” (lowercase “mysterious” and “lady”). The post capitalizes it as “Mysterious Lady” in the text, which is inconsistent with the actual article title, though the reference section correctly uses “Physics Today, 61(1), 55-57.”
CORRECTION (minor): In the text body (line 189), the article title appears as “Fermi, Pasta, Ulam, and a Mysterious Lady” (capitals). The actual title is “Fermi, Pasta, Ulam, and a mysterious lady” (lowercase). Update the in-text mention to use proper capitalization.
10. Margaret Hamilton – Lorenz work period stated twice; first instance is imprecise
Post says (line 203): “In mid-1959, Hamilton began working for meteorologist Edward Norton Lorenz in MIT’s meteorology department.” Post says (line 215): “She was 23 years old.”
Verification: Born August 17, 1936. Began at MIT mid-1959. In mid-1959 she was 22 years old (she turned 23 in August 1959). The Quanta Magazine “Hidden Heroines of Chaos” article states “Hamilton arrived at MIT in the summer of 1959.” If it was before August 17, 1959, she was 22; if after, 23. The 1961 chaos discovery moment would have made her 24 (post-August 1961) or still 24 depending on exact timing. The post says she was 23 when programming the LGP-30 that “uncovered chaos theory,” referring to the 1961 moment. In 1961 she was 24 (from August) or 24 by the time she left (summer 1961 = she turned 24 in August 1961, but left in “summer 1961” – possibly before August). This is ambiguous.
CORRECTION: The closing line (line 215) states “She was 23 years old” when referring to programming the LGP-30. By 1961 (the year of the chaos discovery), Hamilton was 24 (she turned 24 in August 1961 if still at MIT that summer). She was 22-23 when she began at MIT in 1959. The statement “She was 23 years old” conflates her starting age with the age at the discovery moment in 1961. Clarify: she was 22 when she started at MIT in 1959 (turning 23 that August), and 24 when the chaos discovery was made in 1961. The current phrasing is misleading.

ACTIONABLE CORRECTIONS (PRIORITY ORDER)
Must fix before publishing:
- Bartik – “one of only two women” → “the only mathematics graduate” (line 60)
- ENIAC_programmers.md says “the only female mathematics graduate that year”; web sources confirm she was the only mathematics student at all.
- Current text: “one of only two women math majors at the college”
- Replace with: “the only mathematics graduate in her class – the sole student majoring in the subject”
- Holberton – color “beige” → “gray-beige” (line 75)
- Current text: “changed the computer’s exterior color from black to beige”
- Replace with: “changed the computer’s exterior color from black to gray-beige”
- Hamilton – age “23” is ambiguous/likely wrong (line 215)
- Current text: “She was 23 years old.”
- The chaos discovery happened in 1961. Hamilton left MIT in summer 1961 (turned 24 in August 1961). She started in mid-1959 at age 22/23. The “23” likely refers to her age when she started, not the chaos discovery.
- Recommend: “She was 22 when she arrived at MIT in 1959, 24 when chaos theory emerged from the simulations she had set in motion.”
Should fix for precision:
- Dauxois article title capitalization (line 189)
- Current text: “Fermi, Pasta, Ulam, and a Mysterious Lady”
- Actual title: “Fermi, Pasta, Ulam, and a mysterious lady”
- Fix capitalization in body text.
- Arianna Rosenbluth age at PhD (line 221)
- “at age 22” is supported by Radcliffe and IMS sources. Consider adding “– she turned 22 that September” to avoid confusion.
No correction needed, but note:
- “Not marketable” quote for Klara’s memoir – this is consistent with research file and podcast sources but cannot be confirmed as a verbatim archival quote. Consider framing as “told it was not commercially marketable” rather than presenting as a direct quote.
NOTES ON RESEARCH FILE DISCREPANCIES
- ENIAC_programmers.md (line 78) correctly says Bartik was “the only female mathematics graduate that year.” The post incorrectly expanded this to “one of only two women.” This is a regression from the source material.
- Women_of_computing_research.md correctly says “black to gray-beige” (line 60). The post drops “gray-“ from the color description.
- All other facts in the post are either consistent with or more detailed than the research files.
