It’s hard to imagine America’s great poet, Walt Whitman, as a hard-boiled newspaper editor.

But the Long Island-born bard served as editor in chief of the Brooklyn Daily Eagle from 1846 to 1848. The paper’s former offices were later replaced by a warehouse which, in turn, became luxury co-ops that people inhabit today.

The landmarked Eagle Warehouse building, at 28 Old Fulton St. in Brooklyn Heights, by the harbor, bears a commemorative plaque to Whitman and The Eagle.

It has also served as a furniture and silverware storage warehouse and the Brooklyn Law School headquarters until its co-op conversion in the 1980s.

Now a two-bedroom, two-bathroom, 1,450-square-foot third-floor unit in the Eagle Warehouse building is on the market for $1.42 million. The apartment comes with a large entertaining space, 12-foot beamed ceilings, oversized windows and a master bedroom with a walk-in closet.

There’s also a home office that can morph into a third bedroom. Building amenities include a doorman, live-in super, gym, bike room, storage for rent and laundry rooms on each floor.
