George H.W. Bush makes history as only former President to celebrate 94th birthday

Along with another trip around the sun, he became the oldest living president in US history when he celebrated his birthday.

Former US President George H.W. Bush turned 94 on June 12, and was surrounded by a number of his children and grandchildren in Kennebunkport, Maine, on the special occasion.

With his birthday, he became the first US president to turn 94.

Unlike his 90th birthday, which he celebrated by skydiving, his chief of staff, Jean Becker, explained that he was looking forward to a "low-key" day with no presents.

The former president was released from hospital just 8 days prior to his birthday, where he had to be treated for low blood pressure and extreme fatigue.

On June 8, he also celebrated his late wife Barbara Bush's 93rd birthday, the first since the former first lady passed away in April 2018.

His son, Jeb Bush Jr., took to Twitter to wish his father a wonderful day, sharing a photo of the former president watching a military plane flying over the ocean.

Another of his sons, Neil, wrote a column for USA Today in celebration of the big day.

"In this time of reflection, I think about the values of service my parents instilled in our family. Values that supersede partisan politics. Values that unite us and make our society stronger and kinder," he wrote.

Others outside the family also took to social media to share birthday wishes for the former president, including the CIA, of whom Bush was the director for a number of years.

Other presidents who have reached the 93-year mark include Ronald Reagan and Gerald Ford.

But Bush may not be the only US President to reach 94, as former President Jimmy Carter is also due to hit the 94 mark in 2018. Carter celebrates his birthday on October 1.
