Former U.S. President George H.W. Bush has died at 94.

His death was announced late Friday night by his family on Twitter and in a statement by his office.

Bush served as the 41st president from January 1989 to January 1993. His presidency was marked by the fall of the Berlin Wall and by the first Gulf War.

Bush had an extensive career in public service. Prior to his election to the presidency, he served two terms as vice president under Ronald Reagan. He had previously served as head of the CIA and as U.S. ambassador to China.

His son George W. Bush won the 2000 presidential election after a controversial Supreme Court ruling halting a recount in Florida. George H. W. Bush's son Jeb was governor of Florida at the time.

Tributes to the former president poured in.

The White House issued a statement from President Trump saying "Melania and I join with a grieving Nation to mourn the loss of former President George H.W. Bush.

In a statement former president George W. Bush said "George H. W. Bush was a man of the highest character and the best dad a son or daughter could ask for. The entire Bush family is deeply grateful for 41's life and love, for the compassion of those who have cared and prayed for Dad, and for the condolences of our friends and fellow citizens."

Former President Barack Obama paid tribute to Bush on Twitter Friday night, issuing a statement that said, in part, "America has lost a patriot and humble servant in George Herbert Walker Bush. While our hearts are heavy today, they are also filled with gratitude. Our thoughts are with the entire Bush family tonight - and all who were inspired by George and Barbara's example."

Bush's wife Barbara died in April. Bush was the son of U.S. senator Prescott Bush.

He is survived by five children and numerous grandchildren and great-grandchildren.

Funeral arrangements are pending.
