President Obama will mark his 49th birthday today with a dinner celebration with friends in Chicago, while first lady Michelle Obama is vacationing in Spain with daughter Sasha, and older daughter Malia is away at summer camp.

But the president isn’t the only newsworthy person blowing out candles.  August 4 is also the birthday of Elizabeth, The Queen Mother (who would be 110) and famous trumpeter Louis Armstrong (who would be 109). Writer Percy Bysshe, the husband of “Frankenstein” author Mary Shelly, would be 218.
