June 12 (UPI) -- Former President George H.W. Bush celebrated a record-setting birthday Tuesday, becoming the first U.S. president to reach 94 years of age.
The 41st president was at his family home in Kennebunkport, Maine, Tuesday -- and was also honored at the George H.W. Bush Presidential Library and Museum in Houston.
Bush family spokesman Jim McGrath said called the birthday a "very low-key day with family."
Son Neil Bush marked the event in a USA TODAY column that encourages Americans to volunteer.
"Dad also understood that government alone cannot solve all of our community challenges and, from his first day as president, he actively supported volunteer-powered service initiatives," he wrote.
"To celebrate my father's birthday, I want to recognize the 62.6 million Americans who volunteer every year and ask the next generation -- and the generation who raised them -- to take a moment to pledge your service."
Bush has been hospitalized twice since Barbara Bush's death and several times in recent years.
