I want to know the answer to the following question:
Who did Chopin know that became rich in Paris?
All the background I'm provided with is that "His fellow student at the Warsaw Conservatory, Julian Fontana, had originally tried unsuccessfully to establish himself in England; Albert Grzymała, who in Paris became a wealthy financier and society figure, often acted as Chopin's adviser and "gradually began to fill the role of elder brother in [his] life."". Is that enough to answer the question?
