John Glenn Cause of Death: How Did the Astronaut Die?

John Glenn, the iconic astronaut lauded as the last American hero, has died. He was 95.

Ohio State University officials announced Glenn’s death on December 8. He was being treated for a variety of ailments at James Cancer Hospital, where he was hospitalized since last week. When he entered the hospital, officials did not reveal his exact illness, but they said people shouldn’t assume he had cancer because of the hospital’s name. Glenn died with his two children, John and Carolyn, and wife of 73 years at his side, said BBC.

He suffered a stroke two years ago and had heart valve replacement surgery. The Columbus Dispatch said Glenn’s health started to go downhill in 2013 when he had a pacemaker installed and experienced episodes of vertigo. He also had knee replacement surgery, the newspaper said. The Associated Press said Glenn’s eyesight was also failing this year, something he apologized for at a ceremony where an airport was renamed for him.

Ohio Gov. John Kasich announced Glenn’s death on Twitter.

In a statement, NASA called Glenn a “true American hero.”
