The First Lady of the United States is the hostess of the White House.
 The position is traditionally filled by the wife of the President of the United States, but, on occasion, the title has been applied to women who were not presidents’ wives, such as when the president was a bachelor or widower, or when the wife of the president was unable to fulfill the duties of the First Lady herself.
 The First Lady is not an elected position; it carries no official duties and receives no salary.
 Nonetheless, she attends many official ceremonies and functions of state either along with or in place of the president.
 Traditionally, the First Lady does not hold outside employment while occupying the office.
 She has her own staff, including the White House Social Secretary, the Chief of Staff, the Press Secretary, the Chief Floral Designer, and the Executive Chef.
 The Office of the First Lady is also in charge of all social and ceremonial events of the White House, and is a branch of the Executive Office of the President.

Jacques Firmin Beauvarlet, a celebrated engraver, was born at Abbeville in 1731.
 He went to Paris when young, and was instructed in the art by Charles Dupuis and Laurent Cars.
 His first manner was bold and free, and his plates in that style are preferred by some to the more finished and highly-wrought prints that he afterwards produced, although it must be confessed that the latter are executed with great neatness and delicacy.
 Beauvarlet married, in 1761, Catherine Jeanne Françoise Deschamps, a young lady who possessed some skill in engraving, but who died in 1769 at the age of thirty-one.
 He married again in 1770, but became for a second time a widower in 1779.
 Eight years later, in 1787, he married Marie Catherine Riollet, who, like his first wife, was an engraver.
 She was born in Paris in 1755, and is said to have died in 1788.
 Beauvarlet himself died in Paris in 1797.
