(AP) — Jonathan Bush, the younger brother of the late President George H.W. Bush and uncle of former President George W. Bush, has died. He was 89.

A spokesman for the Texas-based George & Barbara Bush Foundation says Jonathan Bush died Wednesday at his home in Jupiter, Florida.

He would have turned 90 on Thursday. In a post on Twitter, the foundation said he was “a fine gentleman and a noble soul.” Jonathan Bush worked in finance.

He was the last surviving of the family’s five siblings. Their father was Prescott Sheldon Bush, a U.S. senator from Connecticut from 1952 to 1963.
