Turn a Blind Eye: Did Nelson Really Start the Phrase?

Every word has a story. Some are stranger than others.

You know the scene: a naval battle, a commander’s signal to retreat, and Admiral Horatio Nelson raising a telescope to the eye that could not see. “I really do not see the signal,” he supposedly declares—and carries on fighting.

It is a wonderfully neat explanation for turn a blind eye, meaning to deliberately ignore something you know is happening. It gives us a hero, a clever act of defiance and a memorable visual joke. Unfortunately for the story, the phrase appears to have a history older than Nelson’s famous moment.

Copenhagen, 1801: the story everyone remembers

During the Battle of Copenhagen on 2 April 1801, Nelson’s fleet was engaged against Danish-Norwegian forces. Nelson’s superior, Admiral Sir Hyde Parker, sent a flag signal indicating that the attack should be discontinued. Nelson, convinced he could still win, continued.

Nelson had lost the sight of one eye earlier in his career. The familiar anecdote says he put his telescope to that blind eye and claimed he could not see Parker’s signal. A biography published in 1809 by Clarke and M’Arthur attributed words to Nelson along the lines of having “a right to be blind sometimes.”

The incident is plausible as a story about Nelson’s defiant personality, and the episode helped cement the association between him and the expression. But there is an important distinction between a famous anecdote and the origin of a phrase. Even if Nelson really did make the quip, that would not prove he invented the wording.

The phrase was already out there

Here is where the timeline spoils the tidy tale. The phrase researcher Gary Martin, writing for Phrase Finder, points to Francis Lathom’s novel Men and Manners, published in 1800—a year before Copenhagen. It uses the image of having “a blind eye to turn” in a comic exchange about a rumoured marriage.

There are also older examples of the related wording. A citation from John Norris’s A Discourse of Walking by Faith (1698) refers to turning “the blind Eye” away from the world’s vanities. That is not necessarily the exact modern idiom in its settled form, but it shows the metaphor was available long before Nelson’s battle.

A letter written by Martha Wilmot in 1823 contains the familiar form “turn a blind eye and a deaf ear.” By then, the expression was clearly understandable without a naval explanation attached.

So the careful conclusion is not that Nelson’s story is definitely fake. It is that Nelson did not coin the expression, because related usage predates the battle. His actions may have helped make the anecdote unforgettable and connect it to the phrase in popular memory.

Why do we love the Nelson version?

Origin stories work best when they give a phrase a single dramatic birthplace. Language usually behaves less neatly. Images such as “blind eye” and “deaf ear” are intuitive metaphors: people can pretend not to notice something by acting as though they cannot see or hear it. Such expressions can develop naturally, and a striking public incident can later become attached to wording that already exists.

Nelson also makes a compelling character in the story. He was a celebrated commander, the battle was real, and his decision to continue fighting fits the image of a bold officer who trusted his own judgement. Once a tale like that becomes familiar, it can overshadow the less cinematic evidence in novels and old texts.

That is how a story can be culturally true in one sense—it captures a reputation—without being the literal origin of a phrase.

Verdict: great story, wrong inventor

What we know: Nelson continued the attack at Copenhagen despite a signal to disengage, and the famous telescope anecdote was recorded soon afterward.

What the evidence complicates: Wording related to “turning a blind eye” appears before 1801, including in print in 1800 and in an earlier, related metaphor from 1698.

What we should avoid claiming: That Nelson definitely invented the exact phrase, or that the entire expression sprang into English from one moment on a ship.

Next time someone says they’re turning a blind eye, you can tell them the admiral may deserve a cameo—but not sole credit in the dictionary. Sometimes the best word story is the one that teaches us to be suspicious of a perfect story.
