La Bourdonnais

Louis-Charles Mahé de La Bourdonnais (1795–1840) was probably the world's best chess player around 1830. Born in Réunion, he followed Deschapelles as the top professional at the "Café de la Régence", Paris. 
La Bourdonnais beat the British player Alexander McDonnell, who was the son of a doctor in Dublin. At this time McDonnell was based in London, and had taken chess lessons from William Lewis, the top London professional at the time. The two matches between La Bourdonnais and McDonnell were played at the "Café de la Régence" in 1834. This series was a total of 85 games.
Both men died soon afterwards, La Bourdonnais of dropsy.
He died penniless in London in December 1840. He was forced to sell his possessions, including his clothes, to pay his creditors. He is buried in Kensal Green Cemetery, London.
