[2] Affected by phobias and hypochondria as a youth, Marie spent much of her time in seclusion, reading literature and writing the personal journals which reveal her inquisitive spirit and early commitment to the scientific method reflected in her father's scholarship.

[4] He admitted that, contrary to what he knew were her hopes, he could not commit to living permanently in France since he was obligated to undertake royal duties in Greece or on its behalf if summoned to do so.

When George brought his bride to Denmark for the first visit with his uncle, Prince Valdemar's wife, Marie d'Orléans, was at pains to explain to Marie Bonaparte the intimacy which united uncle and nephew, so deep that at the end of each of George's several yearly visits to Bernstorff he would weep, Valdemar would fall sick, and the women learned the patience not to intrude upon their husbands' private moments.

[2] During the first of these visits, Marie Bonaparte and Valdemar found themselves engaging in the kind of passionate intimacies she had looked forward to with her husband who, however, only seemed to enjoy them vicariously, sitting or lying beside his wife and uncle.

[2] Although Marie occasionally joined her husband in Greece or elsewhere for national holidays and dynastic ceremonies, their life together was spent mostly on her estates in the French countryside.

[1] From 1913 to early 1916, Marie carried on an intense flirtation with French prime minister Aristide Briand, but went no further because she did not want to share him with his mistress, the actress Berthe Cerny.

[2] When the prince and princess returned in July 1915 to France following a visit to the ailing King Constantine I in Greece, her affair with Briand had become notorious and George expressed a restrained jealousy.

[2] Despite what she described as sexual dysfunction, Marie Bonaparte conducted affairs with Sigmund Freud's disciple Rudolph Loewenstein as well as Aristide Briand, her husband's aide-de-camp Lembessiss, a prominent married French physician, and possibly others.

[9] In 1924, she published her results under the pseudonym A. E. Narjani and presented her theory of frigidity in the medical journal Bruxelles-Médical, having measured the distance between the vagina and the clitoral glans in 200 women.

[15] Although Prince George maintained friendly relations with Freud, in 1925 he asked Marie to give up her work in psychoanalytical studies and treatment to devote herself to their family life, but she declined.

[2] Robed in the diplomatic immunity of a member of a reigning European royal family and possessed of great wealth, Marie was often able to help those threatened or despoiled by World War II.

She was instrumental in delaying the search of Freud's apartment in Vienna by the Gestapo in early 1938, and helped him obtain an exit visa to depart Austria.

She also smuggled out some of his savings in a Greek diplomatic pouch, provided him with additional funding to leave the country, and arranged for the transport to London of some of his possessions, including his analytic couch.

Freud refused to take what he called her "colonial plans" seriously, but Bonaparte nonetheless authored letters to William Christian Bullitt Jr. and Franklin D. Roosevelt to advocate for the idea.

Bored with the pageantry, Marie offered a sampling of the psychoanalytic method to the gentleman seated next to her, the future French president François Mitterrand.

Bonaparte's translation of a sentence in Freud's thirty-first Vorlesung ('lecture'), Wo Es war, soll Ich werden, generated some controversy.
