Jacques Laffitte
Mlle Guimard uniquely sold her hotel by holding a lottery, selling 2,500 tickets at 120 francs each. On 25 May 1785, the Countess of Lau won the hotel with only one ticket. Lau then sold the hotel for 500,000 francs to the banker Jean-Frédéric Perregaux. It was here that Jacques Laffitte began his career as a banker, under the tutelage of Perregaux.
