This article lists calendrical coincidences: events such as births and deaths, occurring on the same day in the calendar but otherwise coincidental, and yet of interest.
Calendar
June
June 24
Theme: Four color theorem. June 24.
1880: Mathematician and academic Oswald Veblen born. His work will find application in atomic physics and the theory of relativity. Veblen will publish a paper (1912) on the Four color conjecture.
2008: Mathematician and academic Gerhard Ringel dies. Ringel was a pioneer of graph theory and contributed significantly to the proof of the Heawood conjecture (now the Ringel-Youngs theorem), a mathematical problem closely linked with the Four color theorem.
