Alexander McDonnell (1798–1835) (1 Jan 1798 Jahr – 14 Sept 1835 Jahr)

Beschreibung:

An Irish chess master, who contested a series of six matches with the world's leading player Louis-Charles Mahé de La Bourdonnais in 1834.

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.

These matches are sometimes seen as having been unofficial World Chess Championship matches, before the title of World Chess Champion existed.
