Jackie, who spoke multiple languages fluently, wrote the personal letters in English and French and gave insight on her and her husband’s quirky eating habits.

"Mr. K," as Jacqueline called her spouse, "can eat nothing fried," she wrote.

"He likes all these creamed foods, so just give me a salad and raw fruit in place of his desserts and vegetables," the future first lady instructed Herbst in a note.

Another letter reveals the future-first lady's concern over the high expenses for food, urging Herbst to economize and stick to a budget of $75 per month while the family was away.

"After the gentleman has left watch out for the expenses for food, the 'bills' feel way too high—you have to economize," Jacqueline instructed Herbst. "I want to do a rerun of $75 a month—while we're away—it'll start with August…I'll make up the difference when I get home."
