|Carl Friedrich Gauss|
The great mathematician would have been 238 years old today, but there was a time that he did not know the date of his birth. Gauss was born to poor, working-class parents, and his mother was not quite literate. She did not record the date of Gauss's birth. Years later, she could just recall that Gauss was born on a Wednesday, and it was 8 days before Ascension Day, which lies on the calendar 40 days after Easter Sunday.
