May 11 links political violence, artistic imagination, and technological change through figures whose stories became larger than their own lifetimes. In 1812, British Prime Minister Spencer Perceval was shot and killed by John Bellingham in the lobby of the House of Commons; Perceval remains the only British prime minister to be assassinated. The date also marks a beginning: Salvador Dalí was born in 1904, later becoming one of the 20th century’s most famous artists through surrealist works such as *The Persistence of Memory*. One event abruptly shook a political institution; the other introduced a singular vision that would reshape popular ideas of art.
Nearly two centuries after Perceval’s death, the contest between human and machine took center stage. In 1997, IBM’s Deep Blue defeated reigning world chess champion Garry Kasparov in the final game of their rematch, a landmark in the history of computing. Across these dates, achievement and influence take sharply different forms: political power can be vulnerable, artistic expression can endure, and machines can challenge skills once seen as distinctly human. In the Northern Hemisphere, May is a season of growth and transition—a fitting backdrop for a list that moves from a violent rupture to a new artistic voice and a technological threshold.
