Alexander McDonnell

Country Ireland / United Kingdom
Born 1798
Belfast, Ireland
World Champion 1835 (unofficial)

Alexander McDonnell (1798-1835) was an Irish chess master, who contested a series of six matches with the world’s leading player Louis-Charles Mahé de La Bourdonnais in the summer of 1834.

Early life

The son of a surgeon, Alexander McDonnell was born in Belfast in 1798. He was trained as a merchant and worked for some time in the West Indies. In 1820 he settled in London, where he became the secretary of the Committee of West Indian Merchants. It was a lucrative post that made him a wealthy man and left him with plenty of time to indulge his passion for chess.

Chess career

In 1825 he became a pupil of William Lewis, who was then the leading player in Britain. But soon McDonnell had become so good that Lewis, fearing for his reputation, simply refused to play him anymore.

Around 1825-1826, McDonnell played Captain Evans, while the latter was on shore leave in London. McDonnell was beaten with what is now regarded in chess circles as the creation of the Evans Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4).

La Bourdonnais matches

At that time the world's strongest player was the French aristocrat Louis-Charles Mahé de La Bourdonnais. Between June and October 1834 La Bourdonnais and McDonnell played a series of six matches, a total of eighty-five games, at the Westminster Chess Club in London. McDonnell won the second match (and is thus considered to have briefly been World Champion), while La Bourdonnais won first, third, fourth and fifth. The sixth match was unfinished.


McDonnell was suffering from Bright's disease, a historical classification of nephritis, which affects the kidneys. In the summer of 1835 his condition worsened and he died in London on 15 September 1835 before his match with La Bourdonnais could be resumed.

When La Bourdonnais died penniless in 1840, George Walker arranged to have him buried in London's Kensal Green Cemetery, near where his old rival McDonnell is buried.
