The guy didn't get that many birthdays: only 18 during his lifetime (remembering that 1800 wasn't a leap year), so we need to acknowledge it whenever we get a chance: today is his 51st birthday. (Update: 53rd. Somehow I missed 1888 and 1988.)
As they said to Frederic in another context:
Though you’ve lived twenty-one years, yet, if we go by birthdays, you’re only five and a little bit over!
A most ingenous paradox. Frederic's turning 3839 today.
