Quick Summary

Laurence Leamer’s new book “Ladies’ Man: The Careless Heart of John F. Kennedy” details the extensive extramarital affairs of President Kennedy from his teenage years through his presidency, revealing his promiscuous nature and the lengths to which he concealed these affairs from the public eye. One significant relationship highlighted in the book involves Inga Arvad, a Danish journalist with ties to Nazi Germany whom Kennedy met in 1941; their correspondence shows deep emotional intimacy despite her controversial background. Another affair detailed is Kennedy’s brief romance with Gunilla von Post, a Swedish aristocrat he met while on a solo trip in France before his marriage to Jacqueline Bouvier.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.

🔮 Von Post’s mother blocked Kennedy’s plan to install her in Manhattan’s Carlyle Hotel where he could drop by regularly.
🔮 The author tells their dramatic story while also interweaving a broader one — how the medical understanding of dementia has progressed in fits and starts over the past 150 years and how, in the last decade, scientists have come to recognize that families like the one Kolker profiles may be key to finding a cure for all types of age-related brain impairment.

Narrative

Author Laurence Leamer, who previously penned “Capote’s Women,” and “Hitchcock’s Blondes” inevitably goes over old ground in this new book, but the vast number of women and incidents he includes makes “Ladies’ Man,” if not edifying, certainly astonishing for sheer scope.
