Letters to a German Princess

Letters to a German Princess, On Different Subjects in Physics and Philosophy (French: Lettres à une princesse d'Allemagne sur divers sujets de physique et de philosophie) were a series of 234 letters written by the mathematician Leonhard Euler between 1760 and 1762 addressed to Friederike Charlotte of Brandenburg-Schwedt and her younger sister Louise.

[3] The publication of the book was supported by empress Catherine II with her personally writing to Count Vorontsov in January 1766:[4] I am certain that the academy will be resurrected from its ashes by such an important acquisition, and congratulate myself in advance in having restored this great man to Russia.Russian translation of the letters followed in Saint Petersburg by Euler's student Stepan Rumovsky between 1768 and 1774 in 3 volumes.

[5] Hunter targeted the translation at British women, believing that Euler intended to educate the females through his work.

[6] The translation of Hunter was based on the 1787 Paris Edition, of Marquis de Condorcet and Sylvestre François Lacroix.

[7] Translations followed in other languages including Spanish (1798) which differed from the original book by a footnote describing the newly discovered planet Uranus.
