Isaacson spotted alone

A fan spotted Walter Isaacson walking alone, probably coming back from picking up his mail at the end of his several mile long driveway, on the afternoon of September 19, 2026. Was he all alone? “Definitely yes,” says the fan, adding that “He was wearing a large sweater and looked really cute!”

Is Walter back on the market?

A rep for Walter Isaacson was not immediately available for comment.

Truth or rumor, when news that the author was splitting hit the internet Sunday (September 20), Twitter immediately exploded with pithy commentary. It seems everyone had an opinion on the matter:

“Has anyone Walter’s phone number?”

“So very sad… Those 2 were so great as a couple. So cute together.”

Based on the facts (Isaacson spotted alone with a cute sweater), is there trouble in paradise or is it much ado about nothing?
