First, a picture taken on the occasion of Barbara Bush’s funeral. Note the comments of the writer regarding the prominent absentee:
Former President Jimmy Carter and his wife Rosalyn were not present either, though that is understandable as they are both above 90.
Barbara Bush was not, however, the longest lived First Lady. She lived to be 92 years 10 months. “Lady Bird” Johnson (94/7), Nancy Reagan (93/8) and Betty Ford (93/3) lived longer.
She was one of two First Ladies whose son became President, and the only one to see her son become President (in 2001). Abigail Adams, wife of John Adams (President in 1797-1801) passed away in 1818 before her son John Q Adams became President in 1825.
The marriage of George Bush Sr and Barbara was the longest-lasting marriage of an US President, at 73 years and 3 months. Next in line are the Carters, married in July 1946 and currently on 71 years 9 months. Rosalyn Carter (born August 1927) is now on 90 years 8 months.
George Bush senior (born June 1924) is the longest-living President at 93 years and 10 months. Next in line is Jimmy Carter (born October 1924), presently on 93 years 7 months.
Bush reached this record only in November 2017 when he crossed the record of Gerald Ford (93 years 5 months, 1913-2006). He is also the last President to have served in World War 2, in a long line going back to JFK and Eisenhower.
An odd coincidence is that 4 successive Presidents (Ford, 1974-1977; Carter, 1977-81, Reagan, 1981-89 and Bush Sr, 1989-93) all celebrated their 93rd birthdays.
Carter has lived longest after his presidential term, which ended in January 1981. He is thus holding the record at 37 years 3 months. Next was Herbert Hoover (President in 1929-33) who survived 31 years and 8 months until his death in October 1964.
