Montaigne
Short and pithy, I too shall retreat to my tower. Great read, highly recommended.
Biography
Balzac: le roman de sa vie
Another great biography by Zweig, this was particularly beautifully written (at least the french version) translated by Fernand Delmas
La Confusion des Sentiments by Stefan Zweig
A great look into the educated of the first few years of the 20th century.
Notes on Le Monde D'Hier Book by Stefan Zweig
Le Monde D’Hier is an excellent read by Stefan Zweig. I highly recommend it. It will provide you with a good feel for the first half of the 20th century.
Notes on Napoleon A Life by Andrew Roberts
Excellent overview of Napoleon’s life. It’s not an academic book yet not romanticized; it hits an excellent balance between both of those.
