Would McCain be the oldest US President? Would Obama be the youngest? Who was the youngest president? Were presidents younger in the past or older? What is the highest number of years a former president lived after leaving office? Who served the longest? Whose term was the shortest?
The chart lets you view presidents lifetimes and terms in office on a regular timeline, aligned by birth, or aligned by start of time in office. When you mouse over a bar, a pop-up displays the president’s name, date of birth and death, and dates in office. Here are a few screenshots.
I found this graphic very interesting, and I even learned a couple things. For example, I knew JFK was the youngest president ever to take office, until this chart showed me that Teddy Roosevelt actually held this honor. If I get ambitious, I may try to replicate this graphic in Excel.
