Presidents that were alive certain amounts of times ago today

Nice list.

Both 48 years and 87 years ago, only sitting presidents Richard Nixon and Herbert Hoover were alive. However, in 1933, FDR was already president-elect after Calvin Coolidge died on January 5. It's also interesting that both presidents who died before, Johnson and Coolidge, ended their presidency in a year that ended with 9 after roughly one and a half term and died in January four years after leaving office.

Quite true
Adams was also the only living President at one point.

There was a period when Hoover was alive and JFK was dead.

There was a period when Hoover was alive and JFK was dead.

One of the more ridiculous notions that the conspiracy theorists latched onto was citing a dry run funeral procession as proof of advance knowledge of JFK's death. In truth, this was advance preparation in case Hoover passed away since he was in declining health and pushing 90.

JFK had health problems and likely would have died long before the 90’s, let alone the 00’s.
