The Mark Twain House was damaged by someone who threw a stone through a window during a vandalism spree that police say also targeted businesses along the same street.

A four-inch paving stone made it through a large storm window of the kitchen at the historic house sometime Wednesday night or early Thursday, but it did not break through an inside pane, said David Cash, a spokesman for the Mark Twain House and Museum.

“They would have had to walk up the hill to do this,” he said. “It’s not something someone could have done from the sidewalk. They had to specifically plan to go up there and do that.”

Cash says he’s not sure if the window was an original in the home, but said it will “probably not be inexpensive to replace.”

He says nothing else was damaged and tours of the home Thursday would not be affected.

“It was the top half of the window and we normally have the blinds drawn halfway down on the window, so it’s really not even noticeable for someone on a tour,” he said.

Samuel Clemens lived at the house from 1874 to 1891, during the period when he authored some of his most famous works, including “The Adventures of Tom Sawyer” and “The Adventures of Huckleberry Finn.”

It has since become a tourist attraction.

“We’re just very disappointed that someone would choose to target a historical home like this, which offers so much to Hartford and Connecticut, but we’re glad the damage wasn’t worse,” he said.

Police said the Twain House was among at least nine buildings that suffered similar damage along Farmington Avenue.

Deputy Chief Brian Foley said police were reviewing surveillance video from the area and are looking for a 6-foot tall bald man with a beard who was seen in the area.
